Протозоози в’єтнамських вислобрюхих свиней на півдні України

Abstract

Goal. To find out the distribution and diversity of the simplest gastrointestinal tract in Vietnamese potbellied pigs by cage- and cage-exercise systems in the South of Ukraine. Methods. Methods used: clinical observation, coprological research. Cryptosporidia were studied by making a native smear according to the generally accepted method, staining of smears was performed by the method of Kester and Romanovsky-Gimza. Eimeriosis and isosporosis were established by studying faeces using the Fuleborn flotation method, as well as in the Kotelnikov–Khrenov modification. Balantidia was recognized on wet smears with Lugol’s solution (diluted from 1:5 to 1:100). Detection of blastocysts was performed by ethyl acetate-formalin concentration and direct microscopy. Results. In the south of Ukraine, protozoa in Vietnamese potbellied pigs are quite common, the causative agents of which are Isospora suis, Cryptosporidium spp., Eimeria suis, Balantidium coli, and Blastocystis spp. Piglets and weaners (8 months) — balantidiosis (24.1–33.4%) and blastocystosis (13.8–26.2%). Conclusions. Isospora suis (34.2%) and Eimeria suis (25.9%) had the highest number of lesions in Vietnamese potbellied pigs on homestead farms in the South of Ukraine, while at cage-growing affection with Isospora suis and Eimeria suis was less by 8.1 and 7.4%, respectively, and lesions of pigs with Balantidium coli and Blastocystis spp. were higher by 7.4 and 6.0%, respectively.
