viruses and bacteria in pediatric diarrhea in thailand: a study of multiple antibiotic-resistant enteric pathogens.children with diarrhea admitted to a rehydration ward of a children's hospital in bangkok were investigated to determine the prevalence of enteric pathogens, the extent of children's previous antibiotic therapy, and the frequency of plasmid-mediated antibiotic resistance among infecting bacteria. rotavirus (36%), enterotoxigenic escherichia coli (18%), shigella (9%), salmonella (6%), campylobacter jejuni/coli (4%), and vibrio cholerae (2%) infections were among 105 children with diarrhea. antibi ...19816275727
a longitudinal study of the prevalence of bacterial enteric pathogens among adults with diarrhea in bangkok, thailand.six hundred sixty adults with diarrhea treated at bamrasnaradura hospital, bangkok, thailand were investigated to determine the prevalence, seasonality, and severity of diarrhea associated with bacterial enteric pathogens in 1980 and 1981. shigella were isolated from 27% and vibrio parahaemolyticus from 19% of the patients studied. enterotoxigenic escherichia coli (5%), salmonella (3%), non-01 vibrio cholerae (3%), campylobacter jejuni (1%), and group f vibrio (less than 1%) were isolated from a ...19836370564
cholera-like illness due to aeromonas sobria.a thai woman from bangkok was admitted to a hospital in paris for a cholera-like illness. a culture of her "rice-water" diarrhea was negative for vibrio cholerae and enterotoxigenic escherichia coli but was positive for aeromonas sobria. this strain produced enterotoxin, cytolysin, proteolysin, hemolysin, and a cell-rounding factor. acute -and convalescent-phase sera showed an increase in neutralizing antibodies to enterotoxin, cytolysin, and hemolysin. the enterotoxin, which was labile at 100 c ...19827054327
bacterial contamination of bottle milk in infants under 6 months in children's hospital, bangkok, thailand.the bacterial contamination of bottle milk samples obtained randomly from 500 infants under 6 months of age who came to the out-patient department of children's hospital bangkok was determined by collecting bottle milk samples prepared at home following interview of their caretakers after obtaining their consent. bacterial contamination was found in 91.8% (459/500) of bottle milk samples. among the positive samples, 82.8% (380/459) contained enteric bacteria, another 17.2% were unidentified bact ...199910928374
bacterial enteric pathogens in children with acute dysentery in thailand: increasing importance of quinolone-resistant campylobacter.current data on pathogen prevalence and drug resistance patterns are important for treatment and vaccine-development strategies. an etiologic study of acute bacterial dysentery was conducted in children up to 12 years of age in 2 major hospitals in and around bangkok. stool samples or rectal swabs and clinical data were collected. standard microbiological methods were used to detect salmonella, shigella, campylobacter, vibrio, aeromonas and plesiomonas. pathogenic e. coli (etec, eiec, stec) was ...200212757222
skin and soft-tissue infections among tsunami survivors in southern thailand.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 imipenem but were resistant to amoxicillin-clavulanate and first-generation cephalosporins.200516231248
an acute gastroenteritis outbreak of vibrio parahaemolyticus o4:k55 in nursing college, thailand.a cluster of acute gastroenteritis among nursing students was noticed on 13th september 2005. between 13th and 17th september 2005, a retrospective cohort study was then conducted to identify the most likely cause of gastroenteritis at a nursing college in bangkok, thailand. self-administered questionnaires, interviews, environmental investigations, and rectal swabs from all participants were carried out. in the investigation, 98.9% female nursing students were investigated and had completed the ...201020962724
prevalence and antimicrobial susceptibilities of vibrio, salmonella, and aeromonas isolates from various uncooked seafoods in thailand.uncooked seafood samples were collected from open markets and supermarkets in bangkok, thailand, and were examined for the presence of vibrio, salmonella, and aeromonas species from january to february 2008. from 120 samples, 272 bacterial isolates were identified through biochemical testing. of all sea bass, shrimp, oyster, and blood cockle samples (30 of each) that were processed for culture, 114 (95%) samples had at least one detectable isolate of vibrio, salmonella, or aeromonas, leaving on ...201222221354
