    ABSTRACT: A blocking enzyme-linked immunosorbent assay (ELISA) with a baculovirus-expressed structural protein was developed for the detection of antibodies to foot-and-mouth disease virus type A. It exhibited 99% specificity with a cutoff of 53% inhibition. Its sensitivity was comparable to the sensitivities of the virus neutralization test and the liquid-phase blocking ELISA, indicating its potential as an alternative assay.

    ABSTRACT: Mongolia had no reported cases of capripoxvirus disease from 1977 until an outbreak of sheeppox in 2006-2007 and then goatpox in 2008. The two outbreaks occurred in geographically distant areas of Mongolia and, most strikingly, were highly species-specific. The 2006-2007 sheeppox outbreak affected no goats and the 2008 goatpox outbreak affected no sheep despite communal herding. The diseases were diagnosed using the polymerase chain reaction and virus neutralisation test. The P32 gene of the Mongolian sheeppox and goatpox viruses from the recent outbreaks were sequenced and compared with an archived 1967 strain of Goatpox virus from Mongolia. The P32 gene of the 2006-2007 Mongolian Sheeppox virus strain was identical to previously published sheeppox strains. The P32 gene of the 2008 Mongolian Goatpox virus strain was identical to the gene from virus isolated from recent goatpox outbreaks in China and Vietnam. The archived Mongolian Goatpox virus strain was unique.

    ABSTRACT: Phylogenetic analysis of the nucleotide sequence of VP1 revealed that a new isolate of foot-and-mouth disease virus (FMDV) serotype Asia 1 identified in Mongolia in 2005 was related to Chinese and Russian strains isolated during the same year. In this study, these strains were defined as East Asian strains having a common geographical origin, and the complete genomic sequence of the Mongolian strain (As1/MOG/05) was determined and compared to other strains of serotype Asia 1. As1/MOG/05 showed 100% identity with an East Asian strain from China (As1/Qinghai/CHA/05) in terms of its VP1 nucleotide sequence. However, the Mongolian strain has a four-amino acid extension in 3D that is missing from all other strains of serotype Asia 1, and which is not due to an insertion. A full genomic scan revealed that the Mongolian strain is closer to the East Asian strain As1/JS/CHA/05 than to all other strains of serotype Asia 1 in nearly all genomic regions. Within the narrow region of low similarity between the two sequences, As1/JS/CHA/05 was found to have a mosaic structure with a partial 2C fragment supposedly transferred from Hong Kong strain As1/HNK/CHA/05. The genomic mosaicism and extension detected in non-structural protein-coding regions in this study may be used to trace the origins and evolution of problematic strains of serotype Asia 1 that have arisen in East Asia since 2005.
