M. pneumoniae and Chlamydia spp. Removal of several stress factors described above results in the condensation of nuclei, the appearance of late proteins, and the production of viable, infectious elementary bodies (EBs). Since repeated infection can certainly be documented in many clinical settings, persistence is thought to also play a role. The persistence would allow constant presentation to the individual immune response of these potentially deleterious immune targets. Makrolid-Antibiotika.

In general, it is likely that this aberrant developmental step leads to the persistence of viable but nonculturable chlamydiae within infected cells over long periods. Chlamydia pneumoniae, an obligate intracellular human pathogen, causes infections of the respiratory tract.
