Influenza virus is not known to affect wild felids. We demonstrate that avian influenza A (H5N1) virus caused severe pneumonia in tigers and leopards that fed on infected poultry carcasses. This finding extends the host range of influenza virus and has implications for influenza virus epidemiology and wildlife conservation.
We investigated influenza interspecies transmission in two commercial swine farms in Thailand. Sera from swine-exposed workers (n=78), age-matched non-swine-exposed healthy people (n=60) and swine populations in both farms (n=85) were studied. Hemagglutination-inhibition (HI) assay was performed on Thai swine H1 viruses (swH1N1 and swH1N2) isolated from(More)
For the purpose of making clear the dynamics of rabies viruses that are prevalent among dogs in Asia, especially Thailand, nucleoprotein (N) genes of isolates derived from Thailand were partially sequenced, and a phylogenetic analysis was performed on the basis of the sequencing data. Firstly, all 27 isolates from Thailand belonged to one group that was(More)
In this report, the genome of the Thai avian influenza virus A (H5N1); A/Chicken/Nakorn-Pathom/Thailand/CU-K2/04, isolated from the Thai avian influenza A (AI) epidemic during the early of 2004 was sequenced. Phylogenetic analyses were performed in comparison to AI viruses from Hong Kong 1997 outbreaks and other AI (H5N1) isolates reported during 2001-2004.(More)
Phylogenetic analysis of partial ORF1 and ORF2 genes of Hepatitis E virus (HEV) strains from pigs in Thailand during 2011–2012 was performed. The result indicated that the current Thai strains belonged to the genotype 3 subgroup 3f, which were similar to the previous HEVs circulating in humans in Thailand.
To determine the seroprevalence of caprine arthritis-encephalitis virus infection (CAEV) in goats in the Western part of Thailand, a cross-sectional serological survey was conducted in three provinces, Ratchaburi, Petchaburi and Kanchanaburi, situated in the western part of the country along the border area. A total of 1,129 serum samples from 74 randomly(More)
Influenza A virus subtype H5N1 causes a rapidly fatal systemic disease in domestic poultry and spreads directly from poultry to humans. The aim of this study was to develop a rapid, cost-saving and effective method for influenza A virus subtype H5N1 detection. The selected primer set was used in single-step RT-PCR for simultaneous detection in multiplex(More)
We sequenced 512 nucleotides in two variable regions of the N gene of 23 rabies isolates from the northeastern part of Thailand by direct sequencing of PCR-amplified products. The sequencing data revealed two new lineages in these rabies isolates. Based on the results of this study together with the findings of our earlier study, the rabies isolates in(More)
Avian influenza (AI) A virus subtypes H5 and H7 cause severe disease in domestic poultry, including chickens and turkeys. Moreover, H5 and H7 AI A viruses can cross the species barrier from poultry to humans. In the present study, we have developed a single-step multiplex reverse transcription-polymerase chain reaction assay (RT-PCR) for detecting H5 and H7(More)
