The role of Acinetobacter nosocomialis and Acinetobacter pittii, which belong to the A. calcoaceticus-A. baumannii complex, in hospital-acquired infections is increasingly recognized. Here we describe a retrospective cohort study of hospital-acquired A. calcoaceticus-A. baumannii complex infections at a university hospital in Thailand. A total of 222 unique(More)
Carbapenem-resistant Acinetobacter baumannii (CRAB) infection is one of the most important healthcare associated diseases worldwide. Although antibiotic use is recognized as a risk factor for CRAB infection, the impact of antibiotic class and length of use on CRAB infection is still unclear. A case-control study was conducted in adult intensive care units(More)
Vibrio parahaemolyticus was isolated from shrimp of five farms located in the Pattani and Songkhla provinces of southern Thailand. Using a PCR method targeted to the unique DNA sequences derived from the plasmid (AP2 primers) and the toxin gene (AP3 primers) of V. parahaemolyticus that caused acute hepatopancreatic necrosis disease (AHPND), a total of 33 of(More)
E. coli serotype 0157 is well known to cause serious illnesses in humans. However, there has been no case report to date of this serotype in Thailand. In this study, we report for the first time E. coli 0157 (designated as PSU120) isolated from a stool sample among 228 diarrheal swab samples at Hat Yai Hospital, Songkhla Province, Thailand. This PSU120 was(More)
BACKGROUND Acinetobacter baumannii is a major hospital-acquired pathogen in Thailand that has a negative effect on patient survival. The nature of its transmission is poorly understood. AIM To investigate the genotypic and spatiotemporal pattern of A. baumannii infection at a hospital in Thailand. METHODS The medical records of patients infected with A.(More)
Due to the existence of sporadic cases caused by methicillin-resistant Staphylococcus aureus (MRSA) in Songklanagarind Hospital, Songkhla, southern Thailand where a canteen is located in close vicinity, this study investigated the presence of MRSA, including mecA-carrying S. aureus (MCSA), contamination in 105 ready-to-eat (RTE) food samples sold in this(More)
BACKGROUND Stenotrophomonas maltophilia has emerged as an important opportunistic pathogen, especially in patients who are immunocompromised, suffering from malignancy or have been hospitalized for a prolonged period. Information of this bacterium in Thailand has not been elucidated. AIMS To investigate the phenotype and genotype of environmental and(More)
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(More)
Methicillin-resistant Staphylococcus aureus (MRSA) plays an important role in nosocomial infections including those in communities. MRSA enables colonization in the nares and throats of healthy people. In this study, investigation of MRSA prevalence from the throats of healthy subjects in southern Thailand revealed that among 153 isolates, 2 showed mecA+(More)
