Mycoplasma hominis: An under recognized pathogen.

Mycoplasma hominis, a commensal of the genital tract, is a potential underestimated pathogen causing both genitourinary and extragenital infections including neonatal infections. Septic arthritis, prosthetic joint infection, central nervous system (CNS) infections, infective endocarditis and abscess formation are common extragenital infections associated mainly with immunocompromised patients. Mycoplasma hominis lipoproteins play an important role in pathogenicity and directly interact with the host immune system. Polymerase chain reaction (PCR) is the mainstay of diagnosis. Increasing resistance to tetracyclines and quinolones which are used for treatment, is a matter of global concern. We reviewed PubMed literature and Google search engine on the recent developments of association of Mycoplasma hominis with various diseases, pathogenesis, diagnosis and treatment.
