In an evaluation of the API 20NE for the identification of Burkholderia spp., 792/800 (99%) Burkholderia pseudomallei and 17/19 (89%) B. cepacia isolates were correctly identified but 10 B. mallei and 98 B. thailandensis isolates were not correctly identified. A latex agglutination test was positive for 796/800 (99.5%) B. pseudomallei isolates and negative for 120 other oxidase-positive gram-negative bacilli.

Dengue virus (DENV) causes dengue fever, a self‐limiting disease that could be fatal due to serious complications. No specific treatment is currently available and the preventative vaccine is only partially protective. To develop a potential drug target for dengue fever, we need to understand its biology and pathogenesis thoroughly. N‐myristoyltransferase (NMT) is an N‐terminal protein lipidation enzyme that catalyzes the covalent cotranslational attachment of fatty acids to the amino‐terminal glycine residue of a number of proteins, leading to the modulation of various signaling molecules. In this study, we investigated the interaction of dengue viral proteins with host NMT and its subsequent effect on DENV. Our bioinformatics, molecular docking, and far‐western blotting analyses demonstrated the interaction of viral envelope protein (E) with NMT. The gene expression of NMT was strongly elevated in a dependent manner during the viral replication phase in dendritic cells. Moreover, NMT gene silencing significantly inhibited DENV replication in dendritic cells. Further studies investigating the target cell types of other host factors are suggested.

Salmonella infection is the second most common cause of diarrhea in Thailand; however, the data on antimicrobial resistance is limited. There were137 Salmonella strains, isolated from patients and 126 strains isolated from chicken meat, collected from Nonthaburi, Thailand during 2002. The top five serotypes of patients isolates were Enteritidis (22%), Typhimurium (11%), Weltevreden (8.8%), Rissen (8%), and Choleraesuis (6.6%) while the top five serotypes of chicken meat isolates were found as follows: Schwarzengrund (11.91%), Hadar (11.11%), Rissen (8.73%), Amsterdam (7.94%), and Anatum (7.94%). Salmonella strains were most resistance to the class of antibiotics that act as inhibitor to nucleic acid synthesis such as antifolates group (Trimethoprim;SXT) and fluoroquinolones (Nalidixic acid; NA, Ciprofloxacin; CIP),while the β lactam antibiotic was more effective, i.e. the 3rd gen cephalosporin (Ceftazidime; CAZ, Cefotaxime ; CTX), Monobactam (Aztreonam; ATM) and carbapenams group (Imipenem; IMP, Meropenem; MEM). The role of class I integron element in transmission of the resistance gene was revealed by detection the gene cassette associated with a class 1 integron in plasmid preparation among 80% of the isolated strains. The gene cassettes containing resistant genes of dhfrA12 (resistant to trimethoprim) and aadA2 (resistant to streptomycin and spectinomycin), were detected more frequently in the resistant strains. These gene cassettes were likely to be transmitted via plasmid, as it could not be detected in genomic DNA.
