The prevalence of intermediately virulent Rhodococcus equi isolates from pig submaxillary lymph nodes from four slaughterhouses in Nakhonpathom province, Thailand, was investigated. The isolates were tested for the presence of virulence plasmids and the 20-kDa virulence-associated protein antigen (VapB) gene by PCR. Of the 734 submaxillary lymph nodes tested, 19 (2.6%) produced positive culture...

The morphologically diverse leafhopper tribe Hyalojassini is reinstated from synonymy under Iassini based on distinctive features of the male genitalia and a key to the Oriental genera is given. The previously monotypic genera Hyalojassus Evans and Coriojassus Evans are revised and redescribed based on study of the type species. The following new genera and species are described from Thailand a...

Antibiotic resistance trends were examined for Shigella species, nontyphoidal Salmonella species, enterotoxigenic Escherichia coli (ETEC), and Campylobacter species isolates from indigenous persons and travelers in Thailand for up to 15 years. Resistance to trimethoprim-sulfamethoxazole was found in >90% of Shigella and 40% of ETEC and nontyphoidal Salmonella isolates. Resistance to nalidixic a...

Porcine epidemic diarrhea virus (PEDV) has continued to cause sporadic outbreaks in Thailand since 2007. Previously, PEDV in Thailand was a new variant containing an insertion and deletion in the spike gene. Herein, full-length genome sequences are reported for two variants of PEDV isolates from pigs displaying diarrhea in Thailand.

To gain a more detailed picture of cryptococcosis in Thailand, a retrospective study of 498 C. neoformans and C. gattii isolates has been conducted. Among these, 386, 83 and 29 strains were from clinical, environmental and veterinary sources, respectively. A total of 485 C. neoformans and 13 C. gattii strains were studied. The majority of the strains (68.9%) were isolated from males (mean age o...

Among uropathogens, uropathogenic Escherichia coli (UPEC) is the most common cause of urinary tract infection (UTI) worldwide, but clinical aspects due to this bacterial species is not fully understood in southern Thailand. Two hundred fifty-four UPEC isolates from patients admitted to Maharaj Nakhon Si Thammarat Hospital, southern Thailand were examined for crucial virulence genes, showing tha...

 The prevalence of cerebral meningitis caused by Cryptococcus neoformans in HIV-infected patients in Eastern Thailand is high. However, little is known about the occurrence of this pathogenic yeast in the environment of this region.  The aim of our study was to characterize the prevalence of C. neoformans, its serotypes and antifungal drug susceptibilities in environmental isolates from Chon Bu...

We investigated the resistance determinant of 13 clinical isolates of carbapenem-resistant Acinetobacter baumannii collected from a regional hospital in the north of Thailand. All isolates were multidrug resistant and produced the OXA-23 carbapenemase. The bla(OXA-23) gene was found adjacent to ISAba1. Furthermore, two isolates carried the metallo beta-lactamase gene, bla(IMP). The bla(OXA-23) ...

Thirteen field isolates of infectious bronchitis virus (IBV) were isolated from broiler flocks in Thailand between January and June 2008. The 878-bp of the S1 gene covering a hypervariable region was amplified and sequenced. Phylogenetic analysis based on that region revealed that these viruses were separated into two groups (I and II). IBV isolates in group I were not related to other IBV stra...

We surveyed the rate of chlamydial and gonococcal infections among human immunodeficiency virus (HIV)-seropositive patients in Thailand as well as the current status of antimicrobial resistance of Neisseria gonorrhoeae and determined the prevalence of penicillinase-producing N. gonorrhoeae (PPNG) in Thailand. A total of 1,158 endocervical swabs from 824 HIV-seropositive patients were collected ...
