Abstract
To investigate the distribution of hantaviruses among animals in Southern and Central Highland area of Vietnam, a total of 1311 serum samples were obtained from rats and Asian house shrews (Suncus murinus) captured at 11 locations between 2006 and 2009. A total of 1066 serum samples from rats were examined for IgG antibodies against Hantaan virus, and there were 30 antibody-positive serum samples from rats that had been captured mainly in a port area and urban area in Ho Chi Minh City (HCMC) (2.8%). All of the antibody-positive rats were Rattus norvegicus, and they had Seoul virus (SEOV) genome in their lungs. SEOV sequences detected from rats captured in Southern Vietnam belonged to the same lineage as those from rats captured at Haiphong Port and a market area in Hanoi City. SEOV strain CSG5 was isolated from a rat captured at Saigon Harbor. Strain CSG5 showed a cross-neutralization pattern almost the same as that of a representative strain of SEOV. A total of 245 Asian house shrews were captured in the Central Highland area and near HCMC. Sera were examined for IgG antibodies against Thottapalayam virus (TPMV), and 32 (13.1%) of the antibody-positive shrews were mainly from the Central Highland area and showed a neutralizing antibody against TPMV. These results indicated that SEOV is distributed among R. norvegicus inhabiting harbor and urban areas of Southern Vietnam and that TPMV or an antigenically related virus is distributed among Asian house shrews in Central Highland area.Entities:
