[The isolation of the herpesvirus from yaks during the epizootic in Mongolia in 1990]. / Vydelenie gerpesvirusa ot iakov vo vremia épizootii v Mongolii v 1990 g.

Strains of virus belonging, according to the results of electron microscopic examinations, to the herpes virus family, were isolated in Vero cell culture from the organs and aphtha secretions in the buccal cavity of yaks developing the disease during an epizootic (more than 500 animals) in Khubsugul aimak (Mongolian village) in Mongolia, 1990. Virus-neutralizing antibodies were detected in the blood sera of the sick animals. The isolated strains differ from herpes viruses affecting man. No infection could be induced by materials of the sick animals in cows and oxen of different breeds in Mongolia. Seroepidemiological surveys are planned because of the mass character of the disease and its repeated occurrence.

Investigations of the antigenic structure and genome of influenza A (H1N1) viruses isolated in the Mongolian People's Republic in 1982, 1983, 1986 and 1987 from children with acute respiratory diseases using monoclonal antibodies and nucleotide sequencing revealed 4 strains identical to the prototype strain A/PR/8/34 (H1N1), variant M. Sinai, and 8 strains closely similar to the epidemic strain A/USSR/90/77 (H1N1) in the antigenic structure and A/Leningrad/54 (H1N1) in the primary structure of HA.

HBsAg has been revealed in the saliva of 5 (20%) out of 25 HBsAg carriers in serum by RIA, but the appearance of HBsAg in the saliva was not correlated with the occult blood in saliva and with the HBsAg titer in the serum.
