ABSTRACT
Background. Echinococcosis are parasitic zoonoses, remains a public health problem of worldwide, including Mongolia . Differential diagnosis between E.granulosus and E.multilocularis has significant implications for epidemiologic studies, treatment of these diseases, since both species occur in Mongolia. Serodiagnostic tests based on detection of antibodies against genus and species-specific antigens have played an important role in differential diagnosis, confirming clinical diagnosis and in epidemiologic studies.Materials and Methods. A total of 107 volunteer participants’ serum samples and additional 11 serum samples from the persons with hepatic cysts were tested for specific IgG against recombinant AgB and recombinant Em18 antigens in an ELISA .Results.rAgB-specific antibody was detected in 2 (3.33) of 60 individuals from Bayankhongor province and no one had positive response to this antigen in 46 individuals from Ulaanbaatar city while rEm18-specific antibody was present in 7 (11.66) and 3 (6.38) respectively. The one individual with typical lesions of active echinococcosis in a liver revealed by abdominal ultrasonography showed significantly higher IgG antibody response to rAgB. We suggest that people need to be provided information not only about cystic echinococcosis but also alveolar echinococcosisand improvement of sanitation and hygiene and to be careful with corsac and red foxes and their feces to prevent those infections.
ABSTRACT
The first Mongolian-Japanese Joint Conference on "Echinococcosis: diagnosis, treatment and prevention in Mongolia" was held in Ulaanbaatar on June 4th, 2009. It was the first chance for Mongolian experts (clinicians, pathologists, parasitologists, biologists, epidemiologists, veterinarians and others working on echinococcosis) joined together. Increase in the number of cystic echinococcosis (CE) cases year by year was stressed. CE in children may be more than adult cases. Alveolar echinococcosis was suspected chronic malignant hepatic tumors or abscesses. Main discussion was as to how to introduce modern diagnostic tools for pre-surgical diagnosis, how to establish the national system for the data base of echinococcosis with the establishment of a network system by experts from different areas. The importance of molecular identification of the parasites in domestic and wild animals was also stressed.
ABSTRACT
AIM: To study circulation of influenza A viruses in western part of Mongolia. MATERIALS AND METHODS: Isolation and characterization of influenza viruses was performed according to recommendations of WHO. RESULTS: Circulation of influenza A viruses subtypes H3N6, H4N6, H1N1, H13N8 in different wild bird species in western part of Mongolia was documented. CONCLUSION: Taxonomic and ecologic heterogeneity of bird species involved in continuous circulation of influenza A viruses was revealed. Subtype H13N8 was isolated for a first time from herring gull on territory of western Mongolia.
