Анализ лабораторной диагностики хламидиоза животных и птицы в Российской Федерации за 2019–2021 гг.

Abstract

Chlamydia infection causes significant economic damage to various branches of animal husbandry and poultry farming. In the system of veterinary and sanitary measures, it is important to detect the pathogen as early and reliably as possible in various forms of the disease. For this purpose, a number of laboratory methods of direct and indirect diagnosis of chlamydia have been developed over the past years. The article analyzes the results of laboratory tests for chlamydia in state veterinary laboratories for 2019–2021, as well as cases of positive results in the study of biological and pathological materials from animals, including birds. During the analyzed period, 2 750 726 samples of material from animals, including birds, were received by state veterinary laboratories for research on chlamydia, of which 2 645 605 (96,7 %) samples were examined by serological methods, specific antibodies were detected in 0,4 % of blood serum from animals (except birds). Positive results of serological tests require mandatory confirmation by methods of direct detection of chlamydia, their antigens, nucleic acids in biological material. The genetic material of chlamydia during polymerase chain reaction studies was detected in 1 % of samples of biological and pathological material from animals, including birds.
