Prevalence of enteropathogenic and enterotoxigenic Escherichia Coli in foods of animal origin in southern Brazil

Abstract

Prevalence of Escherichia coli in foods of animal origin from the city of Pelotas, Brazil, was determined. The ocurrence of enterotoxigenic (ETEC) and classic enteropathogenic (EPEC) serogroups among E. coli isolates was determined. E. coli was isolated from 68% of the food samples surveyed. Of 36 food samples tested, 11(30%) and 24(66%) were positive for EPEC and ETEC strains respectively. However, of 187 E. coli isolates tested, 30(16%) were EPEC compared to 75(40%) which were ETEC. The antibiotic resistance pattern revealed that the isolates were highly sensitive to all antibiotics tested.

Occurrence of Virulence Genes Associated with Diarrheagenic Escherichia coli Isolated from Raw Cow’s Milk from Two Commercial Dairy Farms in the Eastern Cape Province, South Africa

“…The presence of this pathogen in milk proved to be variable in different regions. In Brazil, Aleixo and Aver [ 64 ] reported EPEC in 25% milk samples while 26 (27.7%) from bulk milk were EPEC in Trinidad [ 65 ]. These values were higher than the 3.09% reported by Holko et al [ 66 ] from Slovakia and that of Altalhi and Hussen [ 41 ], Saudi Arabia.…”

Isolation of Enteropathogenic <italic>Escherichia coli</italic> (EPEC) From Raw Milk in Kermanshah by Polymerase Chain Reaction (PCR)

“…We showed that the EPEC prevalence in raw milk samples was 8.25%; however, the presence ofthis pathogene in milk proved to be variable in different regions. In Brazil, Aleixo and Aver (17) reported EPEC in 25% milk samples. In another report, of a total of 175 bulk milk samplesstudied, 83 (47.4%) contained E.coli, and 26 (27.7%) of 94 strains of E.coli isolated from bulkmilk were EPEC (18).…”

Avaliação de métodos para enumeração de microrganismos aeróbios mesófilos e coliformes em leite cru

“…Além da constatação de contaminação fecal, a presença dessa bactéria pode ter um significado particularmente importante, uma vez que existem linhagens enteropatogênicas para o homem e animais (Komacki & Marth, 1982). Alimentos contaminados com E. coli enteropatogênicas são um fator importante na contribuição para a alta incidência de diarréias em países em desenvolvimento (Aleixo & A ver, 1996).…”
