PREVALENCE OF CHLAMYDIA-RELATED ORGANISMS WITH ZOONOTIC POTENTIAL IN FARMS OF THE POLTAVA REGION

Abstract

The aim of our work was to survey private farms in the Poltava region on the prevalence of Chlamydia-like organisms Waddlia chondrophila and Parachlamydia acanthamoebae. Materials and methods: The PCR research was conducted in 2018-2019 at the Institute of Pig Breeding and Аgro-industrial production of the NAAS. The study materials were 300 vaginal scrapings of cows and 28 samples of clinical material of pigs and boars with a suspicion of a chlamydial infection, which were selected at private farms in the Poltava region. Results: Chlamydia-like bacteria Waddlia chrondophila DNA was detected in 132 (44%) samples taken from cows and 8 (28.6%) samples from pigs and boars. Parachlamydia acanthamoebae DNA was not detected in pig samples. However, 43 (14.3%) clinical samples taken from cows were found to be Parachlamydia acanthamoebae - positive. 9 (3%) cows and 2 (7.14%) pigs turned out to be Chlamydia spp. - positive (the samples contained DNA of bacteria of the family Chlamydiaceae). Сonclusions: Our data indicate a relatively high prevalence of Chlamydia-like bacteria in problematic as to chlamydial infection farms in the Poltava region. Chlamydial infection carry a zoonotic threat, therefore it is necessary to observe safety and personal hygiene measures when working with animals. In addition, it is necessary to carry out periodic screening among the population with reproductive disorders and in occupational risk groups, periodic monitoring in livestock farms, to avoid the consuming the unpasteurized milk, and thermally unprocessed meat.
