Treating the mother of an infant with C. trachomatis of the eye, which can evolve into a pneumonia, is recommended. The reticulate body divides through binary fission at approximately 2-3 hours per generation. Genome size: 1,230 kilobase pairs (kbs) (C. pneumoniae) Synthesis mechanism of protein present as they have ribosome. Chlamydia trachomatis is one of several species within the genus Chlamydia that cause human disease, but it is the only one that only infects humans. DOI:10.3201/eid1403.071071, Hayes, L. J., Pickett, M. A., Conlan, J. W., Ferris, S., Everson, J. S., Ward, M. E., & Clarke, I. N. (1990). Future trials are working with closer related species to the human.[36]. [] The C.trachomatis cell wall is unique in that it contains an outer lipopolysaccharide membrane, but it lacks peptidoglycan; within the cell wall, cysteine-rich proteins act as the functional peptidoglycan equivalent. Infection is usually not associated with symptoms (Sex Health 2004;1:115) Symptoms, present in 1/3, include mucopurulent … Different types of C. trachomatis cause different diseases. Browse 23 chlamydia trachomatis stock photos and images available, or search for neisseria gonorrhoeae or treponema pallidum to find more great stock photos and pictures. However, it has been difficult to translate these results to the human species due to physiological and anatomical differences. Discovering and Differentiating New and Emerging Clonal Populations of chlamydia trachomatis with a Novel Shotgun Cell Culture Harvest Assay. 2018;29(5):466-73. doi: 10.1177/0956462417735245. About 84 million worldwide suffer C. trachomatis eye infections and 8 million are blinded as a result of the infection. Elementary bodies are generally present in the semen of infected men and vaginal secretions of infected women. [3] 8 to 16 hours after infection, another set of effectors are synthesized, driving acquisition of nutrients from the host cell. First, C. trachomatis attaches to a new host cell as a small spore-like form called the elementary body. Le réservoir de germe de C.trachomatis est l'homme. C. trachomatis exclusively infects humans. You might receive a one-time dose, or you might need to take the medication daily or multiple times a day for five to 10 days. C trachomatis, genital mycoplasmas, and genital urea-plasmas were found to be widespread among infertile male patients in … [PubMed: 29065772]. C. trachomatis in the lungs presents as the chlamydia pneumoniae respiratory infection and can affect all ages. [5] However, in 1966 electron microscopy studies showed C. trachomatis to be a bacterium. Retrieved from. INTRODUCTION. [7], C. trachomatis strains are generally divided into three biovars based on the type of disease they cause. Genitourinary cases can include genital discharge, vaginal bleeding, itchiness (pruritus), painful urination (dysuria), among other symptoms. [3] In addition to the chromosome that contains most of the genome, nearly all C. trachomatis strains carry a 7.5 kilobase plasmid that contains 8 genes. [29] This was a significant milestone because it became possible to preserve these agents which could then be used for future genomic and phylogenetic studies. Prevalence of Chlamydia trachomatis Genital Infection Among Persons Aged 14–39 Years — United States, 2007–2012 – MMWR September 26, 2014. Chlamydia, infection sexuellement transmissible causée par la Chlamydia trachomatis. (1990). Chlamydia trachomatis and Neisseria gonorrhoeae are the most prevalent bacterial sexually transmitted infections (STI) in the world ().The course of these infections is unpredictable and diverse (2 – 7).Most infections in women are asymptomatic and frequently remain unrecognized, which increases the risk for reproductive tract complications (6, 8 – 10). C. pneumoniae is an important human pathogen, while C. psittaci, the cause of psittacosis is common in avian species, but infects humans only as a zoonosis. Due to its significance to human health, C. trachomatis is the subject of research in laboratories around the world. It lacks muramic acid that is found in the cell walls of most other bacteria. It is ovoid in shape and non-motile.

Chlamydia pneumoniae (TWAR) is a recently recognized third species of the genus Chlamydia that causes acute respiratory disease. Chlamydia trachomatis causes at least 50% of common bacterial . [3] Serovars A through C cause trachoma, which is the world's leading cause of preventable infectious blindness. Jolly M, Curran JJ. Within the inclusion, C. trachomatis transforms into a larger, more metabolically active form called the reticulate body. Canadian Medical Association Journal, 170(8), 1225–1225. Refer to Chlamydia trachomatis by Transcription-Medicated Amplification (TMA) (ARUP test code 0060243). Chlamydia trachomatis is a gram negative organism, meaning that when stained in a laboratory, it will appear pink under a microscope. C. trachomatis is classified into three biovars: the trachoma biovar, the lymphogranuloma venereum (LGV) biovar, and the mouse pneumonitis biovar. Chlamydia trachomatis (Ct) infection is the commonest bacterial sexually transmitted infection worldwide (Howie et al., 2011a, 2011b). Within the family are four species: Chlamydia trachomatis, Chlamydophila pneumoniae, Chlamydophila psittaci, and Chlamydophila pecorum. [4], Like other Chlamydia species, C. trachomatis has a life cycle consisting of two morphologically distinct forms. Microbiol 156: 1394-1404. Chlamydia trachomatis is a major pathogen throughout the world, and preventive measures have focused on the production of a vaccine using the major outer membrane protein (MOMP). Chlamydia isn't difficult to treat once you know you have it. However, the bacteria can present in one of three ways: genitourinary (genitals), pulmonary (lungs), and ocular (eyes). Morphology and genome: Chlamydiae are small, round-to-ovoid organisms that vary in size during the different stages of their replicative cycle. It has approximately 894 likely protein coding sequences. It is ovoid in shape and non-motile. Symptoms. Chlamydia trachomatis, an obligate intracellular bacteria, causes significant infection and disease worldwide. It lacks muramic acid that is found in the cell walls of most other bacteria. Elementary bodies are 200 to 400 nanometers across, and are surrounded by a rigid cell wall that allows them to survive outside of a host cell. The closest relative to C. trachomatis is C. muridarum, which infects mice. motility and . Both are common causes of multiple other conditions including pelvic inflammatory disease and urethritis. La transmission d'homme à homme est assurée par contact direct (sexuel, main, linge souillé) ou indirect (mouche • trachome). Chlamydia, a genus of bacterial parasites that cause several different diseases in humans. Coccobacilli rods are so short and wide that they resemble cocci. … The bacteria are non-spore-forming, but the elementary bodies act like spores when released into the host. Chlamydia trachomatis is the more well-known of the two pathogens, and causes the most common STD in the world, chalmydia, and has been linked with blindness and infertility. .mw-parser-output table.clade{border-spacing:0;margin:0;font-size:100%;line-height:100%;border-collapse:separate;width:auto}.mw-parser-output table.clade table.clade{width:100%;line-height:inherit}.mw-parser-output table.clade td.clade-label{width:0.7em;padding:0 0.15em;vertical-align:bottom;text-align:center;border-left:1px solid;border-bottom:1px solid;white-space:nowrap}.mw-parser-output table.clade td.clade-fixed-width{overflow:hidden;text-overflow:ellipsis}.mw-parser-output table.clade td.clade-fixed-width:hover{overflow:visible}.mw-parser-output table.clade td.clade-label.first{border-left:none;border-right:none}.mw-parser-output table.clade td.clade-label.reverse{border-left:none;border-right:1px solid}.mw-parser-output table.clade td.clade-slabel{padding:0 0.15em;vertical-align:top;text-align:center;border-left:1px solid;white-space:nowrap}.mw-parser-output table.clade td.clade-slabel:hover{overflow:visible}.mw-parser-output table.clade td.clade-slabel.last{border-left:none;border-right:none}.mw-parser-output table.clade td.clade-slabel.reverse{border-left:none;border-right:1px solid}.mw-parser-output table.clade td.clade-bar{vertical-align:middle;text-align:left;padding:0 0.5em;position:relative}.mw-parser-output table.clade td.clade-bar.reverse{text-align:right;position:relative}.mw-parser-output table.clade td.clade-leaf{border:0;padding:0;text-align:left}.mw-parser-output table.clade td.clade-leafR{border:0;padding:0;text-align:right}.mw-parser-output table.clade td.clade-leaf.reverse{text-align:right}.mw-parser-output table.clade:hover span.linkA{background-color:yellow}.mw-parser-output table.clade:hover span.linkB{background-color:green}, Strains that cause lymphogranuloma venereum (Serovars L1 to L3), Most prevalent genital strains (Serovars D-F), Less prevalent genital strains (Serovars G-K, and some strains of Serovar D), Clinical signs and symptoms of C. trachomatis infection in the genitalia present as the chlamydia infection, which may be asymptomatic or may resemble a gonorrhea infection. You also can get chlamydial eye infections (conjunctivitis) through contact with infected body fluids. Comparative study in infertile couples with and without Chlamydia trachomatis genital infection. [4], The C. trachomatis genome is substantially smaller than that of many other bacteria at approximately 1.04 megabases, encoding approximately 900 genes. 45. with . Global Network for Neglected Tropical Diseases. [35], Furthermore, there have been over 220 Chlamydia vaccine trials done on mice and other non-human host species to target C. muridarum and C. trachomatis strains. Perinatal infections may result in inclusion conjunctivitis and pneumonia in newborns. In fact, humans are the only known natural host for C. trachomatis. trachomatis. 2004. Chlamydia . [32] In the ancient world, it was known as the blinding disease trachoma. In vitro models of Chlamydia trachomatis growth have long been studied to predict growth in vivo. The Centers for Disease Control and Prevention recommends chlamydia screening for: 1. In most cases, the C. trachomatis infection is then treated on an outpatient basis with azithromycin or doxycycline. Susceptible cell culture sys… "HPV and Chlamydia trachomatis Co-Detection in Young Asymptomatic Women from High Incidence Area for Cervical Cancer". ROS. Chlamydia trachomatis affects mostly young women, but it can occur in both men and women and in all age groups. Chlamydia trachomatis was first described in historical records in Ebers papyrus written between 1553 and 1550 BC. It is an obligate intracellular human pathogens. [3] If several elementary bodies have infected a single cell, their inclusions will fuse at this point to create a single large inclusion in the host cell. Burton, Matthew J. ; Trachoma: an overview, British Medical Bulletin, Volume 84, Issue 1, 1 December 2007, Pages 99–116. See your doctor if you have a discharge from your vagina, penis or rectum, or if you have pain during urination. La chlamydia est le nom couramment utilisé pour désigner la chlamydiose, une infection contagieuse touchant les appareils reproducteurs provoquée par la Chlamydia trachomatis. Pathogenesis of genital tract disease due to Chlamydia trachomatis. Chlamydiae of Medical Importance. Here, in elementary bodies and in preparations of the outer membrane, we identified native trimers of the MOMP. Sperm. Matsumoto, A., 1988, Structural characteristics of chlamydial bodies, in: Microbiology of Chlamydia (A. L. Barron, ed. morphology which are . [9] Person to person transmission is rare. It has a genome that consists of 1,042,519 nucleotide base pairs. Chlamydia trachomatis infections can be treated with antibiotics. Women aged 15–19 have the highest prevalence, followed by women aged 20–24, although the rate of increase of diagnosis is greater for men than for women. Our findings also show a high concordance (81.1%) and a good agreement (k 5 0.79) between the detection of Mycoplasma genitalium in both specimens. [29][31], In the 1990s it was shown that there are several species of Chlamydia. These are further subdivided into several serovars based on the surface antigens recognized by the immune system. Tetracycline is the most preferred antibiotic to treat C.trachomatis and has the highest success rate. Chlamydia trachomatis is an obligate intracellular bacterium and serovars D-K are tropic for the columnar and transitional epithelial cells of the genital tract. Chlamydia trachomatis has been identified as a causative agent for acute urethral syndrome, defined as acute dysuria and frequent urination in women whose voided urine was sterile or contained <10 5 organisms per milliliter. Chlamydia pneumoniae causes atypical pneumonia. CHLAMYDIA TRACHOMATIS AND RECURRENT SPONTANEOUS ABORTION IN IRAQI PREGNANT WOMEN. Chlamydia trachomatis is an obligate intracellular parasite with elementary bodies (infectious but incapable of cell division) and reticulate bodies (multiply within cytoplasm, but not infectious until they transfer back into elementary bodies) Clinical features. [3], Most people infected with C. trachomatis are asymptomatic. Introduction. DOI:10.1111/j.1749-6632.2011.06194.x, Weir, E. (2004).

Chlamydia trachomatis causes eye, respiratory and genital tract infections. [12] Often, symptoms are similar to those of a urinary tract infection. C. trachomatis is the most common infectious cause of blindness and the most common sexually transmitted bacterium.[3]. [33] It is now known that C. trachomatis comprises 19 serovars which are identified by monoclonal antibodies that react to epitopes on the major outer-membrane protein (MOMP). The impact of Chlamydia trachomatis infection on sperm parameters and male fertility: A comprehensive study. Explore {{searchView.params.phrase}} by color family {{familyColorButtonText(colorFamily.name)}} Unlike the cell walls of most other bacteria, Chlamydia lacks muramic acid which hinders staining of the cell wall. As the inclusion bodies possess a glycogen matrix, therefore, they may be stained with iodine solution also. Chlamydia trachomatis is a gram-negative, obligate intracellular pleomorphic bacterium visible by Giemsa stain. There are three other species in the genus. Zhu Y, Yin B, Wu T, Ye L, Chen C, Zeng Y, et al. Even if you've been tested in the … !Chlamydia trachomatis is a Gram-negative coccobacilli bacteria. Chlamydia trachomatis by Real-time PCR (Reflex to azithromycin resistance by Pyrosequencing) ... variant of Chlamydia trachomatis: genome sequence, morphology, cell tropism and phenotypic characterization. [citation needed], Other research has been conducted to try to get a feel for how to create a vaccine against C. trachomatis, finding that it would be very difficult to create a fully effective or even partially effective vaccine since the host’s response to infection involves complex immunological pathways that must first be fully understood to ensure that adverse effects are avoided. It also occasionally infects other parts of the human body such as the lungs and eyes, though this is less common. C. trachomatis may be treated with several antibiotic medications, including azithromycin, erythromycin, ofloxacin,[9] and tetracycline. [3] From 24 to 72 hours after infection, reticulate bodies transition to elementary bodies which are released either by lysis of the host cell or extrusion of the entire inclusion into the host genital tract. Chlamydiae are obligate intracellular bacteria that cannot be cultured on artificial media. [6], C. trachomatis are bacteria in the genus Chlamydia, a group of obligate intracellular parasites of eukaryotic cells. The elementary body enters the host cell, surrounded by a host vacuole, called an inclusion. The reticulate body contains no cell wall and is detected as an inclusion in the cell. The disease may have been closely linked with humans and likely predated civilization. 8. Serovars L1 through L3 cause an invasive infection of the lymph nodes near the genitals, called lymphogranuloma venereum. The bacteria are non-spore-forming, but the elementary bodies act like spores when released into the host. JID 201(S2):S114–S125. [5] C. trachomatis along with C. pneumoniae have been found to infect humans to a greater extent. Chlamydia trachomatis is a major pathogen throughout the world, and preventive measures have focused on the production of a vaccine using the major outer membrane protein (MOMP). in 1957. Early-stage Chlamydia trachomatis infections often cause few or no signs and symptoms. Elementary bodies are spore-like and infectious, whereas reticulate bodies are the replicative stage and are seen only within host cells. Genus: Chlamydia. Alternative or persistent growth modes in vitro have been shown to occur under the influence of numerous stressors but have not been studied in vivo. Trachoma interactive fact sheet.http://old.globalnetwork.org/sites/all/modules/ It cannot survive outside of a eukaryotic host. Bellaminutti, Serena; Seracini, Silva; De Seta, Francesco; Gheit, Tarik; Tommasino, Massimo; Comar, Manola (November 2014). Gdoura R(1), Keskes-Ammar L, Bouzid F, Eb F, Hammami A, Orfila J. [citation needed]. What is the gram stain for Chlamydia trachomatis? Azithromycin is dosed as a 1 gram tablet that is taken by mouth as a single dose, primarily to help with concerns of non-adherence. Because of the chance of other health problems if you contract chlamydia trachomatis, ask your doctor how often you should have chlamydia screening tests if you're at risk. Here you can learn how to find out the symptoms and signs of this venereal disease, the ways of infection, the methods of diagnosis, treatment and prevention. The bacteria are commonly grown in immortalised cell lines such as McCoy cells (see RPMI 1640) and HeLa cells. Chlamydia isn't difficult to treat once you know you have it. It is distinct from the other two chlamydial species that infect humans, C. trachomatis and C. psittaci, in elementary body morphology and shares less than 10% of the DNA homology with those species. General properties: Life Cycle of Chlamydia trachomatis. A major difference is that chlamydiae lack the thin peptidoglycan layer between the two membranes. Chlamydia trachomatis is an obligate intracellular bacterium that undergoes a complex developmental cycle in which the bacterium differentiates between two functionally and morphologically distinct forms, the elementary body (EB) and reticulate body (RB), each of which expresses its own specialized repertoire of proteins. Chlamydia trachomatis can also infect the rectum, either with no signs or symptoms or with rectal pain, discharge or bleeding. [3] Chlamydial cells cannot carry out energy metabolism and they lack biosynthetic pathways. All the isolates are about 7,500 nucleotides long. It is a most common sexually transmitted bacterial pathogen and major cause of pelvic inflammatory disease (PID) in USA. Chlamydia trachomatis infection is associated with a mucopurulent discharge from the cervix visible on speculum examination, and with hypertrophic cervical ectopy that tends to bleed on contact. Specimen must be collected and transported with test-specific kit (ARUP supply #55224). Chlamydia is a common sexually transmitted disease (STD) caused by infection with Chlamydia trachomatis. Prevalence of Chlamydia trachomatis Genital Infection Among Persons Aged 14–39 Years — United States, 2007–2012 – MMWR September 26, 2014. Infection of . However, as of 2018, this is not a major cause of concern as antibiotic resistance is rare in C.trachomatis compared to other infectious bacteria. This bacteria is associated with causing the disease Chlamydia. C. trachomatis are round cells between 0.3 and 1μm in diameter depending on thereplicative stage. Chlamydia trachomatis, like other chlamydiae species, is characterized by its obligate intracellular lifestyle and unique biphasic developmental cycle.Phylogenetically distinct from bacteria, chlamydiae are members of the order chlamydiales. Explore {{searchView.params.phrase}} by color family {{familyColorButtonText(colorFamily.name)}} Self Collected Vaginal Swab The Dry Swab Is Given To The Doctor To Be Analyzed This Test Is Used For … [16] Trachoma is the primary source of infectious blindness in some parts of rural Africa and Asia[17] and is a neglected tropical disease that has been targeted by the World Health Organization for elimination by 2020. Like other Chlamydia species, C. trachomatis has a life cycle consisting of two morphologically distinct forms. A coccobacillus (plural coccobacilli) is a type of rod-shaped bacteria.The word coccobacillus reflects an intermediate shape between coccus (spherical) and bacillus (elongated). Muramic acid is not detectable in Chlamydia psittaci or Chlamydia trachomatis by gas chromatography-mass spectrometry. This genus contains a total of nine species: C. trachomatis, C. muridarum, C. pneumoniae, C. pecorum, C. suis, C. abortus, C. felis, C. caviae, and C. psittaci. It is ovoid in shape and non-motile. Azithromycin is the recommended medication and is taken as a 1 gram tablet taken by mouth as a single dose. First, C. trachomatis attaches to a new host cell as a small spore-like form called the elementary body. [4] The role of this plasmid is unknown, though strains without the plasmid have been isolated, suggesting it is not required for survival of the bacterium. It's not difficult to treat, but if left untreated it can lead to more-serious health problems. Chlamydia trachomatis is a bacterium that infects the columnar epithelial cells of the urethra, cervix and rectum. The majority of infected women has no symptoms. A species of facultatively aerobic, Gram-negative, coccobacilli assigned to the phylum Chlamydiae. Refer to Chlamydia trachomatis by Transcription-Medicated Amplification (TMA) (ARUP test code 0060243). You may not know you have chlamydia because many people never develop the signs or symptoms, such as genital pain and discharge from the vagina or penis.Chlamydia trachomatis affects both men and women and occurs in all age groups, though it's most prevalent among young women. Biochemical Test of Chlamydia trachomatis. Everett et al. Your sexual partner or partners also need treatment even if they have no signs or symptoms. [5] The reticulate body substantially modifies the inclusion, making it a more hospitable environment for rapid replication of the bacteria, which occurs over the following 30 to 72 hours. [3][4] This form can initiate a new infection if it comes into contact with a susceptible host cell. Chlamydia (kluh-MID-e-uh) trachomatis (truh-KOH-muh-tis) is a common sexually transmitted infection (STI) caused by bacteria. 21–45. Tests for Chlamydia can be ordered from a doctor, a lab or online.[21]. The genus is composed of three species: C. psittaci, which causes psittacosis; Chlamydia trachomatis, various strains of which cause chlamydia, trachoma, lymphogranuloma venereum, and conjunctivitis; and C. They exist in two morphological forms: small infectious elementary bodies 300 nm – 400 nm in diameter and larger replicating reticulate bodies 800 nm – 900 nm in size. The most common strains cause disease in the genital tract, while other strains cause disease in the eye or lymph nodes. 46. important factors in men . Although this disease is effectively treated with antibiotics, concerns for development of resistance prompt the need for new low-cost treatments. 14.2.1 Le trachome. Recommendations for the Laboratory-Based Detection of Chlamydia trachomatis and Neisseria gonorrhoeae — 2014 (March 14, 2014) Page last reviewed: January 4, 2017. Here, we report the development of methods for sampling human infections from the endocervix in a manner that permits a multifaceted analysis of … [4] Neither form is motile. In most cases, the infection resolves within one to two weeks. Risk factors for genitourinary infections include unprotected sex with multiple partners, lack of condom use, and low socioeconomic status living in urban areas. CS1 maint: multiple names: authors list (, Clarke, I. N. (2011). TEXT. This chapter is limited to human diseases caused by chlamydiae. Chlamydia trachomatis is one of several species within the genus Chlamydia that cause human disease, but it is the only one that only infects humans. Designed with ❤️ by Sagar Aryal. Key words: male infertility; Chlamydia trachomatis; semen analysis; sperm morphology Submitted 28 July, 2003 Accepted 10 February, 2004 Introduction Given the number of studies on genital chlamy-diosis, there are surprisingly few dealing with the presence of Chlamydiae in the ejaculate and their potential influence on its quality. Microbiology. Specimen must be collected and transported with test-specific kit (ARUP supply #55224). [28] The bacterium is still classified as gram-negative, C. trachomatis agent was first cultured and isolated in the yolk sacs of eggs by Tang Fei-fan et al. It is non-sporing. Chlamydia trachomatis, genital ureaplasmas, and Mycoplasma hominis in semen and corresponding FVU specimens. [4] Recent research has found that a pair of disulfide bond proteins, which are necessary for C. trachomatis to be able to infect host cells, is very similar to a homologous pair of proteins found in Escherichia coli (E. coli), though the reaction’s speed is slower in C. [citation needed] The elementary body is the dispersal form, which is analogous to a spore. They are typically coccoid or rod-shaped and require growing cells to remain viable. [34] Comparison of amino acid sequences reveals that MOMP contains four variable segments: S1,2 ,3 and 4. Lymphogranuloma venereum is caused by Chlamydia trachomatis and begins with a frequently unnoticed bump on the genitals. [3] These effectors include a number of proteins that modify the inclusion membrane, called Inc proteins, as well as proteins that redirect host vesicles to the inclusion. [5] This is essentially due to the fact that they were found to possess DNA, RNA, and ribosomes like other bacteria. Chlamydia is the most common and very dangerous sexually transmitted disease caused by the microorganisms called Chlamydia trachomatis. Darville T, Hiltke TJ. Figure 1 : Cycle de multiplication des Chlamydia. C. trachomatis is the most common cause of sexually transmitted disease in the United States. Chlamydia trachomatis is a gram-negative, obligate intracellular pleomorphic bacterium visible by Giemsa stain. Chlamydia trachomatis is a gram-negative bacterium that can replicate only within a host cell. [19] Tetracycline is not used because some children and even adults can not withstand the drug, causing harm to the mother and fetus. C. trachomatis is gram negative, non-motile and an obligate intracellular pathogen. WebMD Medical Reference Reviewed by Sabrina Felson, MD on April 02, 2019. pour la femme : salpingite, grossesse extra-utérine, stérilité ; Treatment is often done with both partners simultaneously to prevent reinfection. [18], If treatment is necessary during pregnancy, levofloxacin, ofloxacin, tetracycline, and doxycycline are not prescribed. Clinical Description. Made it possible to use Gram Stain to figure out the bacteria’s Morphology ! Fox, A., Rogers, J. C., Gilbart, J., Morgan, S., Davis, C. H., Knight, S., & Wyrick, P. B. Chlamydia pneumoniae (TWAR) is a recently recognized third species of the genus Chlamydia that causes acute respiratory disease. In culture, C. trachomatis forms inclusions containing glycogen, whereas C. psittaci and C. pneumoniae form inclusions that do not contain glycogen. [9], If the infection has progressed, ascending the reproductive tract and pelvic inflammatory disease develops, damage to the fallopian tubes may have already occurred. Dordrecht: Kluwer Academic.
