Virulence Factors of Chlamydia Spp. Involving Human Infections

Abstract

Chlamydia spp. are the culprit of many human infections with severe complications, especially involving human eye, reproductive system, and lungs. The scope of the project is to delineate the virulence factors of the bacterium that facilitate invasion in human tissues, their mechanism of action, the ability to hide from immune system and the complications of infection. Chlamydia spp. are obligate intracellular pathogens that in their evolution, they use multiple mechanisms to enter host cell, to form the inclusion body, and to promote intracellular replication and survival. The T3SS effectors, the inclusion membrane proteins (Incs), are not only structural components of the membrane but also interfere with the host cell pathways. They also have an atypical mechanism of cell division. Description of the mechanisms of pathogenicity may lead to the development of new ways to face this major pathogen.
