Review of the epizootic situation on chlamydia in animals and birds in the Russian Federation for the period from 2019 to 2021

Abstract

Relevance. Animal chlamydia is widespread throughout the world. Chlamydia infection affects animals, birds, fish, reptiles, as well as humans. Causes significant economic damage to livestock farms. Difficulties in diagnosis are associated with pronounced polymorphism of clinical manifestations. According to the order of the Ministry of Agriculture of the Russian Federation of December 19, 2011 No. 476, chlamydia and enzootic abortion of sheep are included in the list of contagious, including especially dangerous, animal diseases, for which restrictive measures (quarantine) can be established. The purpose of our work is to analyze the epizootic situation for chlamydia in animals and birds on the territory of the Russian Federation for the period from 2019 to 2022.Methods. Based on the data obtained from official reports in the 4-vet (annual) form for 2019–2021, an analysis of the epizootic situation and the prevalence of chlamydia in animals and birds in the Russian Federation was carried out.Results. Epizootological monitoring is carried out in all subjects of the Russian Federation. For the period from 2019 to 2021, the State Veterinary Service examined 2 750 726 different biological and pathological materials. There were 11 970 positive results (0.4%) in all federal districts. The highest percentage of positive results was found among pets (dogs and cats). The most informative biological materials for testing for chlamydia are swabs from the mucous membranes and pathological material. The detection rate of positive results using PCR is higher than that of serological methods
