Abstract
The article reflects the main results of the study of the veterinary and sanitary well-being of
breeding products based on the use of molecular genetic methods. The possibility of transmission
through the sperm of cattle of a large range of infectious agents of viral and bacterial nature,
as well as protozoa, mycoplasmas and fungi, has been established. It was recorded that in the recommendations
of the OIE regarding the assessment of the quality and safety of bull semen, there
are no requirements, but they are mostly directed at the animal itself and at the zone of its origin.
At the same time, the study of 232 series of bull semen in 47 series found an excess of the normalized
value of non-pathogenic microorganisms by 1,2–1,8 times.
Of particular interest are the results of the detection of Coxiella burnetii, the causative agent of
Ku fever, a zoonotic disease characterized in animals by a long-term persistence of the pathogen in
the chronic form of the disease, in samples of genetic material.
Keywords
semen, pathogens, recommendations, molecular genetic methods, PCR reactions.
