Prevalence of diarrheagenic Escherichia coli in children with diarrhea in Salvador, Bahia, Brazil

Detection of diarrheagenic Escherichia coli from children with and without diarrhea in Salvador, Bahia, Brazil

“…The isolation of only one typical EPEC strain confirms a recent trend that has been observed in São Paulo and in other Brazilian states , Franzolin et al 2005, showing a drastic decline in the frequency of typical EPEC with the frequency of atypical EPEC strains on the rise. Up to the 1990s, typical EPEC was the main cause of acute diarrhea in children younger than one year old, of low socio-economic status, in Brazil (Gomes et al 1991, Trabulsi et al 2002, Regua-Mangia et al 2004), but such is currently very rare.…”

“…They only investigated virulence marker genes of ETEC, EPEC, and EIEC, identifying 16%, 8%, and 1% of the children with these pathotypes, respectively. Another epidemiological study conducted by our group examined children with acute endemic diarrhea in Salvador, by colony blot hybridization including other virulence factors (Franzolin et al 2005, Barreto et al 2006. The most frequently isolated was atypical EPEC (10.1%) followed by ETEC (7.5%), and EAEC (4.2%).…”

Epidemiology, Antimicrobial Resistance and &beta;-lactamase Genotypic Features of Enteropathogenic <i>Escherichia coli</i> Isolated from Children with Diarrhea in Southern China

“…The prevalence of EPEC has been reported as 16.3z, 2.7z, and 12.6z in Iran, Singapore, and Thailand, respectively (16)(17)(18). The reported prevalence of EPEC in children in Brazil ranges from 10.1 to 32.7z (19,20). EPEC is rarely reported in China, with only one previous study reporting a prevalence of 0.9z in Beijing (21).…”

Avaliação quantitativa de enteropatógenos em crianças com e sem diarréia na cidade de São Paulo, SP.

“…e E. coli enteroinvasiva (EIEC), o mesmo foi observado em 10% das amostras diarréicas e em 2% das nas diarréicas avaliadas neste estudo. Considerando-se a baixa prevalência das espécies EIEC nos processos diarréicos na população infantil brasileira, os dados deste estudo podem sugerir que espécies de Shigella possam ser os causadores 74 desses processos infecciosos (BUERIS et al, 2007;FRANZOLIN et al, 2005;LEAL et al, 1988;THIEM et al, 2004).…”
