WebNov 22, 2024 · The structure of the cell wall resembles that of Gram-negative bacteria, although there are differences. It does not contain a typical peptidoglycan: it contains completely N-acetylmuramic acid. The cell wall includes an outer membrane that includes LPS and proteins. Despite the absence of peptidoglycan, the cell wall of chlamydia is stiff. Chlamydia may be found in the form of an elementary body and a reticulate body. The elementary body is the nonreplicating infectious particle that is released when infected cells rupture. It is responsible for the bacteria's ability to spread from person to person and is analogous to a spore. The elementary body may be 0.25 to 0.30 μm in diameter. This form is covered by a rigid cell wall (hence the combining form chlamyd- in the genus name). The elementary body induces its own e…
