The article presents the results of serological monitoring research among domestic pigs in the regions of Ukraine regarding circovirus infection during 2013–2015 years.

The aim was to assess the immune status of domestic pigs in different regions of Ukraine regarding the circovirus infection.

Research has been conducted during the 2013–2015 years. During this time, 1,889 blood serum samples from 109 farms located in areas of 96 administrative districts of regions of Ukraine have been studied. The presence of postinfectious specific antibodies against circovirus type II of blood serum in domestic pigs was determined by ELISA using test kits «Swinecheck® PCV2 IgG» («Biovet», Canada), «Ingezim Circovirus IgG/IgM® 11.PCV.K2» («INGENASA», Spain).

By the results of serological monitoring the mapping analysis to seroprevalence of domestic swine to circovirus type II in regions of Ukraine has been conducted.

The results of research of blood serum from domestic pigs for detecting specific antibodies against circovirus second type of ELISA suggest that the overall rate of seroprevalence is 67.6 %, and in different years the number of positive samples compared to number of all studied samples increases — namely 62.4 %, 67.0% and 83.29% in 2013, 2014 and 2015, respectively.

The highest indices of porcine seroprevalence to circovirus type II have been found in Kherson (95.2 %) and Chernihiv (93.42 %) regions.

The revised data of serological studies suggest that the circovirus pathogen is circulating in swine herd in Ukraine.
