Journal Title: Бюлетень "Ветеринарна біотехнологія" - Year 2018, Vol 32, Issue
Abstract
Introduction. The article concerns a comparative study of epizootic and epidemic situation on salmonellosis in Lviv oblast during the last decade. In Lviv oblast, during 2008–2017, the aggravation of the epidemic situation on salmonellosis was observed. These data do not correlate with the data of annual veterinary reports. One of the reasons can be significant reduction in livestock in this oblast. From the other hand, the lack of coordination and partnership between the Health Centers and veterinary profile services leads to such contradictory results. At the same time, the major epidemic threat as reservoirs of salmonellosis can be found in animal products. The results of the serological screening of Salmonella antibodies in cows’ sera samples displays the process of pathogen circulation in cattle herds of Lviv oblast. The goal of the work was to compare the tension of the epidemic situation regarding salmonellosis of humans and the annual reports of veterinary service on salmonellosis in animals. Another goal was to perform a selective serological screening of the S. typhimurium antibodies circulation in the blood of cows from various dairy farms of the oblast. Materials and method. The statistical data analysis method of state medical and veterinary institutions of Lviv oblast for the last decade was used. Bacteriological detection Salmonella was performed according to protocols ISO 6579, ISO 12824 EN, serological screening was performed by immunological methods - agglutination test (AT) and test of indirect immunofluorescence (TIIF). Results of researches and discussion. The results of serological screening of Salmonella antibodies in serum samples from different cow-farms of the region indicated (in AT and TIIF) the circulation of Salmonella or antigen-related microorganisms in herds of cattle. This can be criteria for assessing the tension of the epizootic situation on salmonellosis. Salmonellosis of humans in Lviv oblast was observed annually in 2008–2017. The average annual number of outbreaks was 307.2 ± 58.6 and has a steady upward trend. The greatest epidemic threat of outbreaks of food toxicoinfection is products of animal origin, which account 66.7% of all identified sources and reservoirs of Salmonella. Conclusions and prospects for further researches. The discrepancy of the epidemic and epizootic situation in Lviv oblast indicates that the results obtained by the veterinary medicine laboratories finally are not reliable. The received results show that epidemic situation regarding salmonellosis in Lviv oblast is relevant and serious.
