Forty samples each of pork and chicken meat were collected from local retail markets in Khon Kaen, northeast Thailand, for Salmonella isolation and identification during 2003. Fifty-four isolates of Salmonella obtained from diarrheal patients admitted at a hospital located in the same town were serotyped. All isolates were also tested for antimicrobial(More)
Five blaOXA-48-like-carrying Enterobacteriaceae isolates collected from two Thai patients in December 2012 were characterized. Three Klebsiella pneumoniae isolates giving two different pulsed-field gel electrophoresis patterns and sequence types (ST11 and ST37) from patient 1 harbored blaOXA-48 locating on Tn1999.2, whereas two Escherichia coli isolates(More)
Vibrio parahaemolyticus is responsible for seafood-borne gastroenteritis worldwide. Isolates of V. parahaemolyticus from clinical samples (n=74) and cockles (Anadara granosa) (n=74) in Thailand were analyzed by serotyping, determination of virulence and related marker genes present, response to antimicrobial agents, and genetic relatedness. Serological(More)
This study aimed to examine the prevalence and antimicrobial resistance (AMR) of Salmonella isolates from broiler chickens, pigs and their associated meat products in the Thailand-Cambodia border provinces. A total of 941 samples were collected from pigs and broiler chickens at slaughter houses and from carcasses at local fresh markets in Sa Kaeo, Thailand(More)
This paper describes a simplified capacitor voltage balancing scheme for a modular matrix converter operating in two-level switching mode. The proposed scheme is based on the conventional space vector modulation technique. By using two additional space vectors having opposite direction, the proposed controller is able to regulate all nine capacitor voltages(More)
Livestock-associated meticillin-resistant Staphylococcus aureus, clonal complex (CC) 398, has been reported in Europe, whereas CC9 MRSA has mostly been found in Asia. Therefore, we aimed to detect MRSA on pig farms in north-eastern Thailand. A total of 257 nasal swabs (159 samples from pigs and 98 from pig-farm workers) were collected from three pig farms(More)
Streptococcus suis serotype 2 infections occur in many provinces of north-eastern Thailand, knowledge concerning the prevalence of the common S. suis serotypes (1, 1/2, 2, 5, 7, 8, 9, 14 and 16) among healthy and diseased pigs in upper northeastern Thailand remains limited. This study investigated S. suis isolates from pigs (healthy and diseased) and also(More)
Results Salmonella contaminated to dogs feces in winter, summer and rainy seasons were 13.6%, 13.1% and 9.3%, respectively. The identified most found serovars in winter, summer and rainy seasons were S. Give (23.5%), S. Typhimurium (40%) and S. Weltevreden (21.4%), respectively. Highly resistant amplicillin, sulfamethoxazole/trimetroprim and tetracycline(More)
Twelve non-replicate carbapenemase-negative ertapenem-non-susceptible (CNENS) Escherichia coli isolates from a Thai university hospital between 2010 and 2014 were characterized and compared with two carbapenemase-producing E. coli isolates from the same hospital. Eight unique PFGE patterns were obtained. All produced CTX-M-15 β-lactamase and two isolates(More)
