Chlamydia Chlamydia trachomatis, or simply chlamydia, is an infection caused by pathogen bacterium that can afflict the cervix in women and the urethra and rectum in both men and women. Occasionally other parts of the body (lining of the eyelid, throat and rectum) can be affected.

- Chlamydial Genitourinary Infections - Background. 1  Chlamydial infection can cause disease in many organ systems, including the genitourinary tract. Chlamydiae are small gram-negative obligate intracellular microorganisms that preferentially infect squamocolumnar epithelial cells. They include the genera Chlamydia (of which the type species is Chlamydia trachomatis) and Chlamydophila (eg, Chlamydophila pneumoniae and Chlamydophila psittaci). C trachomatis can be differentiated into 18 serovars (serologically variant strains) on the basis of monoclonal antibody–based typing assays.

Chlamydia Trachomatis Chlamydia is difficult to eradicate because it is an intracellular parasite, which means that any administered antibiotic must cross the host cell membrane and kill the bacterium without damaging the host cell. The drugs of choice are tetracyclines, erythromycin and sulfonamides.

Significance of Chlamydia Infections Ocular infection is caused by the distinct serovar of Chlamydia trachomatis that causes Trachoma (the most common preventable blinding tropical disease). In males Chlamydia trachomatis is the number one cause of non-specific urethritis (NSU), prostatitis and epidydimitis. Chlamydia pneumoniae was long known to cause mild respiratory infections but has recently emerged as an important pathogen associated with atherosclerosis, adult-onset asthma and certain other chronic diseases.

Chlamydia The infection is carried in semen (cum), pre-cum, and vaginal fluids. Chlamydia can infect the penis, vagina, cervix, anus, urethra, eyes, and throat. Most people with chlamydia don't have any symptoms and feel totally fine, so they might not even know they're infected.

Glossary A-F Chlamydia trachomatis was once thought to be viruses due to their reliance on the biosynthetic machinery; however they are now classified as bacteria due to the presence of a cell wall, DNA, RNA, and ribosomes (4). The organism encompasses two forms, elementary bodies and reticulate bodies.

- Doctors suspect these infections based on symptoms, such as a discharge from the penis or cervix. In most cases, doctors diagnose chlamydial infections by doing tests that detect the bacteria’s unique genetic material (DNA). Usually, a sample of the discharge from the penis or cervix is used.

- The pathophysiologic mechanisms of chlamydial infection are poorly understood at best. Chlamydia infects columnar epithelial cells, which places the adolescent female at particular risk because of the presence of the squamocolumnar junction on the ectocervix until early adulthood. The initial response of epithelial cells to infection is a neutrophilic infiltration, followed by lymphocytes, macrophages, plasma cells, and eosinophilic invasion.

Basic Questions and Answers About Chlamydia Chlamydia is a common STD that can infect both men and women. It can cause serious, permanent damage to a woman's reproductive system, making it difficult or impossible for her to get pregnant later on.Chlamydia can also cause a potentially fatal ectopic pregnancy (pregnancy that occurs outside the womb).he only way to avoid STDs is to not have vaginal, anal, or oral sex. If you are sexually active, you can do the following things to lower your chances of getting chlamydia: 1  Being in a long-term mutually monogamous relationship with a partner who has been tested and has negative STD test results;

Fertilization The sperm first burrow through the cells of the corona radiata. Then, upon contact with the zona pellucida, the sperm bind to receptors in the zona pellucida. This initiates a process called the acrosomal reaction in which the enzyme-filled “cap” of the sperm, called the acrosome, releases its stored digestive enzymes. These enzymes clear a path through the zona pellucida that allows sperm to reach the oocyte.

How is chlamydia tested, by blood or urine? Chlamydia (pronounced: kluh-MID-ee-uh) is a sexually transmitted disease (STD) caused by bacteria called Chlamydia trachomatis. Although you may not be familiar with its name, chlamydia is one of the most common STDs. Because there often aren't any symptoms, though, lots of people can have chlamydia and not know it. The bacteria can move from one person to another through vaginal, oral, or anal sex.

- Chlamydomonas is surrounded by a rigid cell wall, but unlike plant cells in which the cell wall is made of cellulose (a glucose polymer), the Chlamydomonas wall is made of fibrous glycoproteins (in most algae it consists of carbohydrate polymers) and is triple-layered. The apical papilla is a small hemispherical or flattened projection of

EducationalObjectives The chlamydia, which are incorrectly called the PLT viruses or Bedsonia or basophilic viruses, are bacteria which are obligate intracellular parasites of higher animals (mammals and birds). The members of this group share a unique development cycle, a common morphology and a common family antigen.
