| Abstract | ||
| Purpose: To examine the dissemination of blaTEM and blaSHV genes in Escherichia coli isolate from patients with significant bacteriuria. Methods: During the study period, antibiotic susceptibility patterns were studied in a total of 38 isolates of E. coli. The isolates were also examined to determining the presence of blaTEM and blaSHV genes by PCR assay. Conjugation experiments were performed by using rifampicin resistance E. coli MM294 as the recipient. Results: All isolates were resistance to at least five of the antibiotics tested (multidrug resistance, MDR) and sensitive to imipenem. PCR assay revealed that 57.1% and 14.3% of the isolates carried blaTEM and blaSHV genes, respectively, additionally 9.5% of the isolates harbored both genes. Conjugation experiments and PCR trials confirmed that the blaTEM positive E. coli isolates tested were able to transfer thisgene in transconjugants. Conclusions: There was a high occurrence of MDR isolates in patients with significant bacteriuria and the blaTEM gene was common among isolates | ||
