Diseases of the reproductive system caused by infectious diseases

A typical manifestation of some infectious diseases is damage to the reproductive system of the body, which is accompanied by abortions and their complications, namely: retained placenta, metritis, vulvovaginitis, mastitis, infertility in females; orchitis and balanoposthitis in males, which is associated with the tropism of the pathogens of these infections to the tissues of the reproductive organs. That is, impaired reproductive function in animals is often the result of infectious pathologies. Such diseases as brucellosis, leptospirosis, listeriosis, tularemia, chlamydia, campylobacteriosis are quite often the cause of abortions and other pathologies of the reproductive system in both animals and humans. The main method of their diagnosis and differentiation is laboratory bacteriological, serological, luminescent microscopic and molecular genetic studies. To cure these diseases, anti-epizootic measures and therapeutic and prophylactic agents have been developed and implemented, which allow diagnosing and controlling such infections, conducting effective treatment of sick animals and preventive treatments, including using immunobiological vaccine preparations. Systematic implementation of preventive and health-improving measures has led to the eradication in Ukraine of such an extremely dangerous infectious disease common to animals and humans as brucellosis of cattle and small cattle (causative agents Br. melitensis, Br. abortus). Vaccination plays an important role in the complex of measures for the treatment of brucellosis in animals. Live vaccines are used, made from weakly virulent, attenuated immunogenic strains. Immunization with live vaccines creates non-sterile immunity, which over time turns into sterile immunity. Experience in the use of live vaccines has shown that the drugs are effective when used to combat brucellosis in combination with veterinary-sanitary, economic and administrative-economic measures. At the same time, such diseases as leptospirosis, listeriosis, tularemia, chlamydia, campylobacteriosis, despite the developed effective measures of prevention and control, are occasionally registered and can lead to quite severe epizootic situations and cause significant economic losses. Anti-epizootic preventive and health-improving measures provided for the current instructional materials on these diseases allow controlling the epizootic situation with the prospect of improving the health of disadvantaged herds. Key words: brucellosis, leptospirosis, listeriosis, tularemia, chlamydia, campylobacteriosis.
