Chlamydia CrpA

Chlamydia trachomatis, commonly known as chlamydia, is one of four bacterial species in the genus Chlamydia. Chlamydia is a genus of pathogenic bacteria that are obligate intracellular parasites. C. trachomatis is a Gram-negative bacterium. It is ovoid in shape and nonmotile. The bacteria are nonspore-forming, but the elementary bodies act like spores when released into the host. The inclusion bodies of C. trachomatis were first described in 1907 by Stanislaus von Prowazek and Ludwig Halberstädter during research on trachoma. C. trachomatis agent was first cultured in the yolk sacs of eggs by Professor Tang Fei-fan, et al. in 1957. CT442, also known as CrpA, is a 15-kDa protein of undefined function that has previously
been shown to be associated with the Chlamydia inclusion membrane.
