Última Isolation of Shiga toxigenic Escherichia coli from butcheries in Taquaritinga city, State of São Paulo, Brazil BJM Rodolpho,Daniela; Marin,José Moacir. Shiga toxigenic Escherichia coli (STEC) has been implicated as the cause of several human diseases. Samples (ground beef, grinding-machines and human hands) from 23 butcheries were assayed for E. coli using standard microbiological methods, and 287 isolates were submitted to polymerase chain reaction for the detection of stx 1, stx 2 and eae genes. Four STEC isolates were recovered, two from ground beef and two from grinding-machines; all harbored the stx 2 gene and were negative for the eae gene. All E. coli isolates including the four STEC were screened for antibiotic resistance. High levels of resistance against several antimicrobial agents were detected; those most commonly observed were to tetracycline (76.6%), amoxicillin (64.1%) and cephalothin...

Ano: 2007 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1517-83822007000400004 Presence of extraintestinal pathogenic Escherichia coli in butcheries in Taquaritinga, SP, Brazil BJM Santo,Edilene; Rodolpho,Daniela; Marin,José Moacir. The study was conducted in twenty-three butcheries in the city of Taquaritinga, State of São Paulo, Brazil, surveyed during a 10 months period. Among two hundred and eighty-seven Escherichia coli strains isolated from samples of ground beef, meat-grinding-machines and the hands of manipulators, five were recognized as extraintestinal pathogenic E. coli (ExPEC), showing virulence factors (P and S fimbriae, hemolysin and aerobactin) and presenting multidrug resistance. Retail-sold food may constitute an important vehicle for the dissemination of ExPEC in communities, giving rise to reasons for concern.
