[Detection of leptospirosis infection in certain wild and domestic animals in Mongolia].

AIM
Serological examination for leptospirosis of domestic and certain species of wild animals in Mongolia.


MATERIALS AND METHODS
Collection of material from domestic and wild animals was performed in 2009--2010 in 7 aimags (regions) of Eastern, Central and Southern Mongolia. Serological study of filter paper dried blood samples obtained from 51 specimens of cattle and small cattle, camels, and 545 specimens of rodents of various species was performed in microagglutination reaction (MAR) of leptospirae with 13 reference strains.


RESULTS
There is a presence in certain regions of Mongolia of anthropurgic loci of leptospirosis infection including arid zones where ecological conditions do not favor the development of epizootic process. The results of the study indicate the epizootic significance of Tarassovi serogroup leptospirae in cattle and Sejroe serogroup (probably hardjo serovar) in goats, sheep and camels. Results of serological studies of desert and steppe specimens of wild fauna of Mongolia suggest a possibility of circulation of leptospirae in natural foci.


CONCLUSION
Detection in a significant percent of cases in tarbagan and long tailed ground squirrel blood sera of agglutinins to Pomona (mozdok) leptospirae with negative MAR results for Pomona (pomona) strain suggests a presence of a pathogen of a previously unknown serovar. However final conclusion could be made only after the isolation of cultures of the pathogen and their identification.
