Porcine deltacoronavirus (PDCoV) was detected by RT-PCR in 12 of 97 (12.4%) intestinal samples collected during 2015 from piglets with diarrhoea in Thailand, Vietnam and Lao PDR. Spike, membrane and nucleocapsid genes were characterized, and phylogenetic analyses demonstrated that PDCoV isolates...

This study revised taxonomically some previously misidentified Aristolochia species in Vietnam. As a conclusion, these specimens were previously misidentified as A. heterophylla, A. indica, A. westlandii and A. zollingeriana, are here corrected to A. longgangensis, A. cambodiana, A. fangchi and A....

Mandarin (Citrus reticulata) is a perennial fruit tree of economic value for poor farmers in the northern mountains of Vietnam. Since 2009, powdery mildew has been observed on this host, mainly from February to May in many valleys of Bac Son, Lang Son. The heavily infected trees often became...

The whitefly Bemisia tabaci (Gennadius) is one of the most threatening pests to crop production in tropical and subtropical regions. Severe damage results from its effective transmission of plant viruses; the most serious are members of the genus Begomovirus. B. tabaci is a complex of at least 34,...

Highly pathogenic avian influenza (HPAI) H5N1 viruses are endemic in poultry and cause continued inter-species transmission to human in Asia, such as China and Vietnam, leading to pandemic concerns and socio-economic challenges. Phylogenetic analysis of H5N1 viruses isolated from China and Vietnam...

While swine production is rapidly growing in South-East Asia, the structure of the swine industry and the dynamic of pig movements have not been well-studied. However, this knowledge is a prerequisite for understanding the dynamic of disease transmission in swine populations and designing...

The hemagglutinin ectodomain (HA1 subunit) from highly pathogenic avian influenza (HPAI) isolate (A/chicken/Vietnam/14/2005) was cloned and expressed using a baculovirus expression vector. Biosynthesis, glycosylation and secretion of the HA1 proteins, with natural or a melittin signal peptide at...

Foot-and-mouth disease (FMD) is a major constraint to transboundary trade in animal products, yet much of its natural ecology and epidemiology in endemic regions is still poorly understood. To address this gap, a multidisciplinary, molecular and conventional epidemiological approach was applied to...

Salmonellosis is a public health concern in both the developed and developing countries. Although the majority of human non-typhoidal Salmonella enterica (NTS) cases are the result of foodborne infections or person-to-person transmission, NTS infections may also be acquired by environmental and...
