Serotypes, virulence genes and intimin types of verotoxin-producing Escherichia coli and enteropathogenic E. coli isolated from healthy dairy goats in Spain

Distribution Pattern of EcoR Phylogenetic Groups Among Shiga Toxin-Producing and Enteropathogenic Escherichia coli Isolated From Healthy Goats

“…The broad range of detection of STEC was reported in other investigations in Germany (56.1%), Spain (47.7%), Bangladesh (10.0%), and Nigeria (7.5%) (28)(29)(30)(31). In the current study, the genotypic profile stx1 had the most frequency (12%) followed by stx1/stx2 (4%), eae (2.8%), stx1/eae (0.8%), and stx2 (0.4%) which is comparable with other studies carried out by other researchers; Oliveira et al (32) reported the genetic profiles stx1, stx2, and stx1/stx2, with the prevalence rates of 24.1%, 34.7%, and 41.2%, respectively.…”

These rates were 69.8% (stx1), 0.9% (stx2), and 22.5% (stx1 and stx2) in the study by Cortes et al (29). In most of comparative researches, EPEC has been isolated less than STEC.…”

“…Among all of them, geographical variation, age, environmental conditions, seasonal difference, sampling method, detection technique, some farm management practices such as the administration of antibiotics, improper feeding, and use of contaminated food and water have recently emerged as the most important reasons (29,(41)(42)(43).…”

Phenotypic and Genotypic Characterization of Antimicrobial Resistance in Enterohemorrhagic Escherichia Coli and Atypical Enteropathogenic E. Coli Strains from Ruminants

“…The 226 selected strains were isolated from 210 animals (48 from diarrheic animals and 162 from healthy animals) in 73 herds and have been described previously. 4,7,16,17 Antimicrobial testing was performed using the disc diffusion method, according to the recommendations of the Clinical and Laboratory Standards Institute. 5 Measurement of growth inhibition areas allowed the classification of each strain as susceptible, intermediate, or resistant, according to data provided by the Clinical and Laboratory Standards Institute.…”

Caracterização molecular de Escherichia coli enteropatogênica atípica em animais silvestres capturados na Região Amazônica

“…A subclasse γ1 foi identificada concomitantemente em pacientes diarreicos e em suínos; a intimina κ, identificada tanto em alimento (carne crua) como em pacientes diarreicos; e as classes ε2, η2 e ι1, tanto em pacientes diarreicos como em assintomáticos, demonstrando a grande variabilidade e distribuição das aEPEC entre as amostras analisadas. Anteriormente, Moura et al 31 descreveram o subtipo β1 como o mais frequente em isolados de animais e humanos; nesse mesmo sentido, Aidar-Ugrinovich et al 22 já haviam descrito que, no Brasil, o subtipo β1 se apresentava como o mais frequente em EPEC isoladas de bovinos; semelhante ao observado por Cortés et al 32 , que identificaram o subtipo β1 como o mais prevalente nas cepas isoladas de ovinos, seguido do subtipo γ2. No presente estudo, os subtipos mais frequentes foram β1 (amostras 574, 812 e 813), β2 (amostra 630), ζ (amostras 445 e 447) e ε (amostras 611 e 856), presentes em oito aEPEC das 263 E. coli identificadas.…”
