These Chlamydiota can grow only where their host cells grow, and develop according to a characteristic biphasic developmental cycle. [12] [13] [14] Therefore, clinically relevant Chlamydiota cannot be propagated in bacterial culture media in the clinical laboratory. They are most successfully isolated while still inside their host cells.
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]
The Chlamydiaceae are a family of gram-negative bacteria that belongs to the phylum Chlamydiota, order Chlamydiales. Chlamydiaceae species express the family-specific lipopolysaccharide epitope αKdo-(2→8)-αKdo-(2→4)-αKdo (previously called the genus-specific epitope). Chlamydiaceae ribosomal RNA genes all have at least 90% DNA sequence ...
Chlamydia is a genus of pathogenic Gram-negative bacteria that are obligate intracellular parasites. Chlamydia infections are the most common bacterial sexually transmitted diseases in humans and are the leading cause of infectious blindness worldwide.

Chlamydia trachomatis (/ k l ə ˈ m ɪ d i ə t r ə ˈ k oʊ m ə t ɪ s /) is a Gram-negative, anaerobic bacterium responsible for chlamydia and trachoma. C. trachomatis exists in two forms, an extracellular infectious elementary body (EB) and an intracellular non-infectious reticulate body (RB). [2]
All Chlamydiota are anaerobic bacteria with a biphasic developmental lifecycle that depends on obligately intracellular growth in eukaryotic host cells. Chlamydophila was recognized by a number of scientists in 1999, [ 3 ] with six species in Chlamydophila and three in the original genus, Chlamydia .
Chlamydia pneumoniae [1] is a species of Chlamydia, an obligate intracellular bacterium [2] that infects humans and is a major cause of pneumonia.It was known as the Taiwan acute respiratory agent (TWAR) from the names of the two original isolates – Taiwan (TW-183) and an acute respiratory isolate designated AR-39.
