Epidemiological situation of salmonellosis in beekeeping farms of south-east regions of Azerbaijan

The article is devoted to the study of bee salmonellosis in beekeeping farms in the north-eastern regions of Azerbaijan. As a result of studies conducted in 2013-2021. in the beekeeping farms of the north-eastern regions of Azerbaijan, it has been established that salmonellosis is widespread and causes significant economic damage to beekeeping. The studies were carried out in beekeeping farms with bees of the Gonagkend population of the Bozdag Caucasian breed Apis mellifera subsp. caucasica Gorbachev, 1916. 720 bee colonies were subjected to research. Infection in the Gusar district is 62.5%, in Khachmaz district - 37.5%, in Guba district - 75.0%. The seasonal dynamics, the degree of spread of invasion along the altitudinal zones, depending on the strength of bee colonies, were studied. Depending on the strength of the bees, the dynamics of salmonellosis in bee colonies weakens with warming weather, that is, from March to May. So, in May, the average infection in families with poor nutrition is 18.47%, in families with average nutrition - 12.77%, in families with strong nutrition - 10.53%. The spread and development of salmonellosis is inversely proportional to the increase in ambient temperature.
