| detection of resistance phenotype and genotype of avian escherichia coli in hebei province. | we investigated the resistance of avian escherichia coli to commonly used clinical antibiotics in hebei province. it is of significance to reveal the extent and mechanism of drug resistance, as well as to prevent and control colibacillosis. we investigated the resistance of 132 e. coli isolates to 5 kinds of antibiotics (including β-lactams, aminoglycosides, tetracyclines, sulfonamides, and chloramphenicol) using the kirby-bauer drug susceptibility test, and resistance genes were detected by pcr ... | 2013 | 23960114 |
| survey on tetracycline resistance and antibiotic-resistant genotype of avian escherichia coli in north china. | the experiment was performed to investigate the tetracycline resistance and antibiotic-resistant genotype of avian escherichia coli in north china and to analyze the correlation of genotype and phenotype. the resistance of 164 e. coli isolates (from beijing, tianjin, inner mongolia, shanxi, and hebei regions of china) to tetracycline, doxycycline, and minocycline was investigated by using a drug susceptibility test. the results show that the rate of resistance to tetracycline antibiotics was 89. ... | 2012 | 23091131 |
