[Chlamydiosis of urogenitary tract in humans]

Chlamydiae are bacteria commonly found in the environment of human life and they cause many diseases. Chlamydial infections are common among men and women, although they are more often diagnosed in women and they are frequently asymptomatic, due to the biology of chlamydiae. Incorrectly diagnosed and untreated, they cause many complications which can lead to infertility in both, men and women. This work presents the diseases caused by chlamydiae of the urogenitary tract, including environmental chlamydiae, so far in Polish literature rarely presented, which extends the panel responsible for chlamydial genital tract disease, particularly in women. A major problem is that the knowledge of the immune mechanisms that occur in the case of infection with these bacteria, especially in view of prevention of these infection, mainly in the context of creation of the vaccine. Also important fact from the knowledge of immunity in chlamydiosis is base for diagnosis of these infection.
