Abstract
Introduction. Leptospirosis is a dangerous infectious disease of animals and humans caused by bacteria Leptospira. Leptospirosis causes significant economic losses in livestock production, in particular in pig breeding. The article presents the results of the conducted studies on the etiological structure of the detected Leptospira serovars in the studied blood serums of the imported pigs for leptospirosis by microscopic agglutination test (MAT). The goal of the work was to analize the etiological structure of Leptospira serovars in blood sera of imported pigs for leptospirosis. Materials and methods. To achieve this goal, during 2009−2014, 29412 samples of blood sera from pigs imported into Ukrainian farms from Austria, Belgium, the UK, Denmark, Ireland, Latvia, Germany, Poland, Hungary, France, the Czech Republic were examined by microscopic agglutination test (MAT). Results of research and discussion. It was shown that during the study period the results were different. Thus, seropositive animals were discovered during imports from Austria (2011, 2014), Denmark (2009), Latvia (2011−2012), Germany (2013), Poland (2012), the Czech Republic (2014). Such animals did not need restrictions and were suitable for use in farms. In all other cases, the presence of seropositive animals was diagnosed among imported animals: from Belgium (2009), Great Britain (2009−2014), Denmark (2010−2014), Ireland (2009, 2011), Latvia (2013), Germany (2010−2012), Poland (2009, 2010, 2013), Hungary (2009−2013), France (2009, 2010, 2011, 2013), the Czech Republic (2009, 2010, 2012). It is should be noticed that seropositive animals had a diagnostic titer of antibodies to both individual Leptospira serovar and to several of them. Conclusions and prospects for further research. 1. Infection rate of imported pigs during 2009−2014 was 12.2%, which indicates the necessity of continuous serological monitoring. 2. During 2009−2014 the largest number of pigs had diagnostic titers of antibodies to L. icterohaemorrhagiae (71.2%), to L. bratislava (14.3%), and to several leptospira serogroups (12.2%). 3. There is a high risk of leptospirosis pathogen introduction to Ukraine.
