摘要: Twenty-five (27 %) of 92 clinically normal macaques were found to have β-haemolytic Escherichia coli isolated from their faeces. Five six isolates chosen for further characterization had multiple antibiotic resistance and PCR-positive cytotoxic necrotizing factor 1 (cnf1) with a demonstrated cytopathic effect in vitro. By repetitive element sequence-based PCR genotyping, genetic similarity was established selected isolates. We believe this be the first report E. strains producing CNF1 non-human primates.
