Chlamydia cell culture is a test in which the suspected Chlamydia sample is grown in a vial of cells. The pathogen infects the cells, and after a set incubation time (48 hours), the vials are stained and viewed on a fluorescent light microscope. Cell culture is more expensive and takes longer (two days) than the other tests.
Of various Chlamydiota that cause human disease, the two most important species are Chlamydia pneumoniae, which causes a type of pneumonia, and Chlamydia trachomatis, which causes chlamydia. Chlamydia is the most common bacterial sexually transmitted infection in the United States, and 2.86 million chlamydia infections are reported annually.

Haemophilus influenzae, Gardnerella vaginalis, and Chlamydia trachomatis are coccobacilli. Aggregatibacter actinomycetemcomitans is a Gram-negative coccobacillus prevalent in subgingival plaques. Acinetobacter strains may grow on solid media as coccobacilli. Bordetella pertussis is a Gram-negative coccobacillus responsible for causing whooping ...
Chlamydia may also take the form of a reticulate body, which is in fact an intracytoplasmic form, highly involved in the process of replication and growth of these bacteria. The reticulate body is slightly larger than the elementary body and may reach up to 0.6 μm in diameter with a minimum of 0.5 μm.
Chlamydia, or more specifically a chlamydia infection, is a sexually transmitted infection caused by the bacterium Chlamydia trachomatis. [3] Most people who are infected have no symptoms. [ 1 ] When symptoms do appear, they may occur only several weeks after infection; [ 1 ] the incubation period between exposure and being able to infect ...
Anthony Van Leeuwenhoek was the first to view these organisms using a microscope he created. [14] The temperature and pH of saliva makes it conducive for bacteria to survive in the oral cavity. Bacteria in the oral cavity include Streptococcus mutans , Porphyromonas gingivalis , and Staphylococcus . [ 15 ]
