Nine (10%) out of 90 hepatitis C virus (HCV) isolates from hepatitis patients and commercial blood donors in Thailand were not classifiable into any of genotypes I/1a, II/1b, III/2a, IV/2b, V/3a or VI/3b by RT-PCR with type-specific primers deduced from the HCV core gene. These isolates were sequenced over a 1.6 kb stretch of the 5'-terminal sequence and 1.1 kb of the 3'-terminal sequence cover...
background hepatitis e virus (hev), a zoonotic pathogen, uses several species of animal as reservoirs. swine is considered as the major reservoir for hev infection in humans. genotype 4 hev is the dominant cause of hepatitis e disease in humans in china. objectives although many researches revealed that genotype 4 hev is the main genotype that prevalent in eastern china, few researches have don...

BACKGROUND Evidence suggests that the PfKelch13 mutations that confer artemisinin resistance in falciparum malaria have multiple independent origins across the Greater Mekong subregion, which has motivated a regional malaria elimination agenda. We aimed to use molecular genotyping to assess antimalarial drug resistance selection and spread in the Greater Mekong subregion. METHODS In this obse...
In two short surveys of lignicolous, fruitbody-forming ascomycetes in Thailand and southern China, six species were found, of which five were new to science. Two fungi with affinity to the Dothideomycetes, one from Thailand and one from China, are described here in the new genus ALIQUANDOSTIPITE: and included in the new family Aliquandostipitaceae. Aliquandostipite khaoyaiensis was found in a t...
The human population history in Southeast Asia was shaped by numerous migrations and population expansions. Their reconstruction based on archaeological, linguistic or human genetic data is often hampered by the limited number of informative polymorphisms in classical human genetic markers, such as the hypervariable regions of the mitochondrial DNA. Here, we analyse housekeeping gene sequences ...
The H5N1 avian influenza virus outbreak among zoo tigers in mid-October 2004, with 45 animals dead, indicated that the avian influenza virus could cause lethal infection in a large mammalian species apart from humans. In this outbreak investigation, six H5N1 isolates were identified and two isolates (A/Tiger/Thailand/CU-T3/04 and A/Tiger/Thailand/CU-T7/04) were selected for whole genome analysi...
The purpose of this study was to determine the prevalence and distribution of HCV genotypes among voluntary blood donors in northern Thailand. From 1998 to 2000, 167 serum samples which tested positive for anti-HCV antibodies in the screening of voluntary blood donors from 5 provinces in northern Thailand were selected for genotyping. Viral RNA was extracted from the sera. The core-E1 region of...
The aim of the present study was to genotypically characterize Vibrio cholerae strains isolated from cholera patients in various provinces of Thailand. Two hundred and forty V. cholerae O1 strains, isolated from patients with cholera during two outbreaks, i.e. March 1999-April 2000 and December 2001-February 2002, in Thailand, were genotypically characterized by NotI digestion and pulsed-field ...
mammalian hosts (9). Drug resistance or sensitivity is based on sequences of M2 and NA. Substitution within residues including L26I, V27A/I, A30S, and S31N of the M2 ion channel protein was used to predict amantadine-resistant mutants, and H274Y of the NA was used to predict for oseltamivir resistance (10). The virus observed in 2006 isolates from Phichit was resistant to amantadine but sensiti...
