The Kyrgyz Republic is a hyper-endemic area leading to a 2–10-fold increase in the brucellosis prevalence infection in the population of Central Asian Region countries. Today more than 99% of the livestock are kept in private small farms and there is a limited by coverage of vaccination and monitoring programs testing. As a consequence there has been an increasing trend in the incidence of brucellosis in small cattle farms.

Aim of the Study:

To modify ring reaction for the assessment of sour cream as a brucellosis transmission factor.

Hygienic, epidemiologic and laboratory methods (ring reaction for detection of Brucella in milk) were used in the study.

High incidence of brucellosis in the human population and in animals with an increasing trend was found–the rate of increase in the human population over a 9 years period of observation was +292,6% (56,5 cases per 100,000 versus 19,3 cases per 100,000). Brucellosis occurs in all regions of the republic, in the present time it has lost its spring-autumn seasonality and occupational character–more than 54% of brucellosis infected persons are unemployed. In adults the highest incidence is in the age group 19–49 years and there is an increasing incidence in children. A direct association between the incidence of the human population and the incidence in oxen and small cattle was found. The main infection transmission factors are milk and milk products (73.3%). Out of 1219 samples 23 milk and sour cream samples were found positive.

The modified method of ring reaction is specific and sensitive in the testing of sour cream produced from ill cows. Results of the study have been used in the practice of Centers for Sanitary-Epidemiologic Surveillance, the Veterinary-Sanitary Evaluation Laboratory of the State Veterinary Department of the Kyrgyz Republic.
