Abstract

Introduction. Despite not huge efforts to combat brucellosis, in a number of countries, including Azerbaijan, decisive positive results have not yet been achieved. Many households began to keep livestock, which could lead to an increased risk of brucellosis in children. Aim. Assessment the influence of individualization of livestock breeding on the incidence of brucellosis in children. Material and methods. The work was carried out in 14 settlements of the Baku urban agglomeration located on the Absheron Peninsula. An epidemiological survey was carried out on 486 individual farms, selected by a blind method, 331 of them kept livestock. Serological diagnosis was carried out using the Huddleson and Wright tests. A total of 1702 children were examined, of which 533 children lived in households that did not contain livestock, 796 children lived in farms that kept livestock, and 373 children lived in village 2-7-storey buildings. When statistically processing the results of the study, the definition of Student’s t-criterion, χ² and correlation coefficient was used. Results and discussion. Infection of children averaged 15.2±0.9%, as the age of children (≤3>15 years) increases, it increases from 6.0±1.8 to 21.1±2.8%. The infection rate of children living in households with livestock is higher than without them - 10.5±0.7 and 2.8±0.4%. As the number of livestock increases, the infection rate in children increases from 9.1±4.4 to 29.6±2.1%. The seropositivity of children living in individual households that do not keep livestock and in village 2-7-stage buildings is approximately the same and amounts to 2.8±0.4 and 1.9±0.3%, respectively (t= 1.80; P>0.05) and is much inferior to the seropositivity of children living in individual households with livestock: 10.5±0.7% (t=9.63; P<0.001). Conclusion. The epidemiological situation of brucellosis among children has deteriorated in recent years, which is associated with the individualization of livestock breeding. Therefore, the search for new approaches to the prevention of brucellosis in the population should be carried out taking into account these changes.
