Abstract
During the study of the epizootological situation for swine leptospirosis in Sumska oblast. It was determined that the disease has some extent of spread. Generally, swine of 3-7 month of age are affected. Leptospirosis is being registered all year round but the majority of sick and positive swine were identified in winter-spring period. The acquired data in Sumska oblast suggest that during last 9 years there have been significant variations in epizootological indicators for leptospirosis. Factors that facilitate this situation include unsatisfactory rodent infestation countermeases and inadequate veterinary and sanitary requirements adherence. Quantity of the affected regions is changing yearly. The largest quantity of problematic regions where positive animals were identified has been reported in 2008, and the least has been reported in 2013 (4 regions). On average 13 regions report positive animals yearly. Maximum quantity of households where positive animals were detected has been found in 2008 comprising of 67 households; the minimal quantity has been reported in 2013 with 6 households. The quantity of positive animals changes yearly and reaches maximum of 22.6% in 2016 and a minimum of 5.5% in 2013. In Sumska oblast positive leptospirosis reactions are caused by L. Icterohaemorrigiae – 4,77 %, L.Tarassovi – 3,11 %, L. Bratislava – 7,36 %, L.Sejroe – 1,74 %, L. Grippotyphosa – 0,39 %, L.Canicola – 1,69 %, L.Hebdomadis – 0,25 %, L.Pomona – 1,39 % and also mixed leptospira infections which constitute 15.03% of positive reactions. Mixed positive leptospira antigens reactions have been most often reported in 2008 (510 cases) and most seldom in 2015 (27 cases). We connect the lower quantity of such cases to the decrease of animal monitoring in the region.
