| subtypes of intimin among non-toxigenic escherichia coli from diarrheic calves in brazil. | one hundred and five strains of escherichia coli that were isolated from calves with diarrhea in the state of são paulo, brazil, and were negative for enterotoxins and cytotoxins, were examined for the eae gene. four (3.8%) strains were positive by polymerase chain reaction (pcr) and were shown to produce intimin by using western blot with specific antiserum against the conserved n-terminal region of intimin. subtyping of the intimins was done by pcr with specific primers and by western blot wit ... | 2000 | 10680651 |
| molecular typing of antimicrobial-resistant shiga-toxin-producing escherichia coli strains (stec) in brazil. | antimicrobial resistance patterns and molecular characteristics were determined in thirty-two shiga-toxin-producing escherichia coli (stec) strains previously identified in são paulo state associated with human infections (n = 21) and in cattle feces (n = 11). the highest resistance rates were identified for tetracycline (100%), streptomycin (78%) and trimethoprim-sulfamethoxazole (56%). eleven stec strains showed resistance to ampicillin and carried bla(tem) that was confirmed as bla(tem-1) in ... | 2010 | 21126577 |
