OBJECTIVE To investigate the cause of infective diarrhea in children, special distribution of the infection and the drug sensitivity. PATIENTS AND METHODS We carried out pathogenic detection and drug sensitivity tests for one hundred and twenty-six children with diarrhea, including 67 children in infant group (0-<1 year) and 59 children in child group (1-5 years). RESULTS Fat particles and ...

To characterize the extended-spectrum beta-lactamases (ESBLs) in diarrheagenic Escherichia coli from Korea in 2008-2011, we screened seven enterotoxigenic E. coli (ETEC) and one enteroaggregative E. coli (EAEC) that produce ESBLs from a nationwide survey. All eight isolates produced CTX-M-type ESBLs, including CTX-M-12 (n = 4), CTX-M-14 (n = 2), and CTX-M-15 (n = 2). PCR-based replicon typing i...

We identified different diarrheagenic (DEC) Escherichia coli pathotypes isolated from 1,207 children with and without acute endemic diarrhea in Salvador, Bahia, Brazil collected as part of a case-control study. Since the identification of DEC cannot be based on only biochemical and culture criteria, we used a multiplex polymerase chain reaction developed by combining five specific primer pairs ...

BACKGROUND Diarrheagenic Escherichia coli (DEC) are important bacterial causes of childhood diarrhea in Brazil, but its impact in adults is unknown. This study aimed at investigating DEC among children and adults living in endemic areas. METHODS A total of 327 stools specimens were collected from children (n = 141) and adults (n = 186) with diarrhea attending health centers. Diarrheagenic E. ...

The probability that clinical cholera results from the interaction of a toxin produced by Vibrio cholerae with the intestine was proposed by Koch (59) and by other early investigators of the disease. Many subsequent studies support this conclusion. The nature of this toxin and its mode of action, however, remained obscure until recent years when the development of animal models closely resembli...

Collared peccaries (Pecari tajacu) roam the forests of natural areas in America. Wild collared peccary appears to be a carrier for bacteria associated with infections humans and animals, however, presence diarrheagenic E. coli (DEC) pathotypes has not been studied captive peccary. This study aimed prevalence DEC, susceptibility antibiotics, frequency β-lactamase genes (ESBL) faeces. DEC strain...
