Antigenic variation of type A foot and mouth disease (FMD) virus in Thailand was examined using a total of 82 field viruses isolated between 1986 and 1989. A two-dimensional serum microneutralisation test was used to compare these isolates to a reference strain, A15 Bangkok 1960 (A BKK/60). Viruses regarded as unrelated to A BKK/60 were compared to another reference strain, A22 Nakhon Pathom 19...

In this present study, the serotype of 40 Streptococcus suis isolates from submaxillary glands of pig carcasses sold in wet markets in Chiang Mai Province, northern Thailand, was investigated. Eleven serotypes, including types 2, 3, 4, 5, 7, 8, 9, 17, 21, 22 and 31, were found in the isolates by a Multiplex PCR combined with serum agglutination. Of the eleven serotypes present, type 3 was the m...

The geographical distribution of 65 clinical isolates of methicillin resistant Staphylococcus aureus (MRSA) recovered from 7 hospitals in Thailand was investigated. The presence of mecA gene in MRSA was determined by specific PCR with the use of primers 5'-GTAGTTGTCGGGTTTGGT-3' and 5'-GGTATCATCTTGTACCCA-3'. Chromosomal DNA restriction analysis with SmaI was resolved by pulsed-field gel electrop...

The cultivation of exotic Penaeus vannamei in Thailand began on a very limited scale in the late 1990s, but a Thai government ban on the cultivation of P. monodon in freshwater areas in 2000 led many Thai shrimp farmers to shift to cultivation of P. vannamei. Alarmed by the possibility of Taura syndrome virus (TSV) introduction, the Thai Department of Fisheries required that imported stocks of ...

Introduction A new contagious disease characterized by severe neurological problems and severe drop in egg production has emerged in broiler and layer duck farms in China, Malaysia and Thailand (1,3,6, 9,). The causative agent of the outbreaks was identified as a duck Tembusu virus (DTMUV), which is a singlestranded RNA virus, belonging to the Ntaya group, a member of mosquito-borne Flavivirus....

The present study was performed to analyze molecularly the phylogenetic positions of human-infecting Trichostrongylus species in Mazandaran Province, Iran, which is an endemic area for trichostrongyliasis. DNA from 7 Trichostrongylus infected stool samples were extracted by using in-house (IH) method. PCR amplification of ITS2-rDNA region was performed, and products were sequenced. Phylogenetic...

The assassin bugs of the genus Acanthaspis Amyot & Serville (Reduviinae) from China are revised. Fourteen species are recognized, described or redescribed and illustrated. Three species, A. fulviconnexa, A. melanota, and A. octoguttata, are described as new to science. Acanthaspis subinermis Hsiao 1976 is synonymized with A. laoensis Distant 1919. A key for the identification of Chinese species...

BACKGROUND Treatment failure of chloroquine for P. vivax infections has reached high levels in the eastern provinces of Indonesia, however, in vitro characterization of chloroquine resistance and its associated molecular profile have yet to be determined. METHODS Using a modified schizont maturation assay we investigated the in vitro chloroquine susceptibility profile and molecular polymorphi...

Among 777 patients transferred to 4 hospitals in Bangkok from southern Thailand after the tsunami of 26 December 2004, there were 515 with skin and soft-tissue infections. The most common organisms isolated were Aeromonas species (145 [22.6%] of 641 isolates from 305 patients). Most isolates were susceptible to aminoglycosides, third- and fourth-generation cephalosporins, quinolones, and imipen...

The genetic heterogeneity of the nitrite reductase gene (nirK and nirS) fragments from denitrifying prokaryotes in a non-agricultural forest soil in Thailand was investigated using soil samples from the Plant Germplasm-Royal Initiation Project area in Kanchanaburi Province, Thailand. Soil bacteria were screened for denitrification activity and 13 (from 211) positive isolates were obtained and f...
