Livestock salmonellosis in the Irkutsk region

Abstract

The analysis of the incidence of livestock (cattle and pigs) of salmonellosis in the territory of the Irkutsk region during 2004–2016 was carried out. It was found that the incidence rate of cattle was 5.4±0.62 per 100 thousands livestock, pigs − 4.0±0.04 0/0000. The dynamics of reducing of the incidence of pigs was identified. Negative rates of increase in the incidence of animals were revealed. The epizootic index was 1.0. Salmonella of nine species (Salmonella dublin, S.enteritidis, S.choleraesuis, S.typhimurium, S.london, S.lindi, S.wernigerode and S.othmarschen) in cattle and five species (S.choleraesuis, S.enteritidis, S.typhimurium, S.rochdale and S.arizonae) in pigs were identified as the causative agent of the infection. S.dublin was dominated at the etiology of salmonellosis in cattle (75.1 %) (p≤0.05), S.choleraesuis – in pigs (89.2±2.9 %) (p≤0.01). Salmonellosis in cattle was recorded in 11 districts of the Irkutsk region, in pigs – in nine districts.
