Surveillance of swine influenza viruses (SIVs) in 31 pig farms in northern and southern parts of Vietnam was conducted. Six H3N2 influenza A viruses were isolated from a pig farm in southern Vietnam. They were novel genetic reassortants between a triple-reassortant SIV and a human seasonal H3N2 virus. Their hemagglutinin and neuraminidase genes were derived from a human virus circulating around...

The 'acaecate' Pheretima group from Vietnam is revised, with description of a new species, Polypheretima mekongmontis sp. nov. A total of 18 species of three genera, Metapheretima Michaelsen, 1928, Planapheretima Michaelsen, 1934, and Polypheretima Michaelsen, 1934 has been recorded from Vietnam. Caecate species of Planapheretima are included here as well. Planapheretima arboricola (Rosa, 1890)...

This two-part investigation examined associations between service in Vietnam and indices of long-term general life adjustment using a national sample of male and female members of the Vietnam generation. In Study I , we documented reasonably high levels of satisfaction and attainment among Vietnam veterans, levels that differed minimally, on average, from those who served elsewhere and those wh...

We examined the distribution of genetic mutations associated with resistance to the M2 ion channel-blocking adamantane derivatives, amantadine and rimantadine, among H5N1 viruses isolated in Vietnam, Thailand, Cambodia, Indonesia, Hong Kong, and China. More than 95% of the viruses isolated in Vietnam and Thailand contained resistance mutations, but resistant mutants were less commonly isolated ...

A serosurvey of feline herpesvirus type 1 (FHV-1), feline calicivirus (FCV), and feline parvovirus (FPV) in cats from Ho Chi Minh City area in southern Vietnam was conducted in December 1998, and we compared the results with our previous results in northern Vietnam (Hanoi area). The positive rate of FHV and FCV in domestic cats were 44% and 74%, respectively. They were rather higher than those ...

Extensive research in Vietnam and elsewhere has shown that live bird markets (LBMs) play a significant role in the ecology and zoonotic transmission of avian influenzas (AIs) including H5N1 and H7N9. Vietnam has a large number of LBMs reflecting the consumer preferences for live poultry. Under pressure to mitigate risks for H7N9 and other zoonotic AIs, Vietnam is considering, among other mitiga...

Sesame (Sesamum indicum L.) is known as the king of oil seeds in Vietnam due to the high oil content (50 – 60%) of its seed. The purpose of this study was to evaluate morphology of sesame from different origins. Seventeen sesame varieties originating from El Salvador, Tanzania, Kenya, India, Cambodia and Vietnam were studied. The field experiment was carried out in the Mekong Delta region, Viet...

CONTEXT Premarital sexual activity is thought to be rising in Vietnam. However, there is little evidence documenting such an increase, and it is unknown whether levels of premarital sex differ between northern and southern Vietnam and whether premarital sex occurs primarily with a future spouse. METHODS Surveys conducted in northern Vietnam (Red River Delta) and southern Vietnam (Ho Chi Minh ...

With the increasing economic importance of the Asia-Pacific Region, the economic interdependence among countries in the region has gradually enhanced. With the continuous opening up of the two countries, Sino-Vietnamese economic relations have also been deepened. However, the export trade between Vietnam and China has been competitive. China and Vietnam seek to dominate or join an agreement tha...
