Presence of Antibodies Against Serovar in Serum Samples from Cattle in Ukraine.

The article presents data on serological studies of 573 sera samples of cattle that were collected from the farms affected by leptospirosis in different regions of Ukraine in the period of 2014-2015. Samples were investigated by the microscopic agglutination test (MAT), which was conducted within eight serological groups of and nine serovars: (serovars and ), (serovar ), (serovar ), (serovar ), (serovar ), (serovar ), (serovar ), and (serovar ). The circulation of serovar among cattle has been observed in all 11 regions of Ukraine investigated within 25.8-60.0% of the leptospirosis-positive serum samples in these regions. Antibodies in the cattle sera against serovar (serogroup ) were detected in 139 of the 370 cows reacting positively in MAT. Overall, they were detected in 24.3% animals out of the total of 573 cows investigated. These are the preliminary results, however, in our opinion, they should allow to include the serovar in a standard panel of strains for MAT in Ukraine.
