Antibiotic resistance genes are typically isolated by cloning from cultured bacteria or by polymerase chain reaction (PCR) amplification from environmental samples. These methods do not access the potential reservoir of undiscovered antibiotic resistance genes harboured by soil bacteria because most soil bacteria are not cultured readily, and PCR detection of antibiotic resistance genes depends...
The aacA29b gene, which confers an atypical aminoglycoside resistance pattern to Escherichia coli, was identified on a class 1 integron from a multidrug-resistant isolate of Pseudomonas aeruginosa. On the basis of amino acid sequence homology, it was proposed that the gene encoded a 6'-N-acetyltransferase. The resistance gene was cloned into the pET23a(+) vector, and overexpression conferred hi...
The aac(6')-Ib gene is the most prevalent gene that encodes aminoglycoside-modifying enzymes and confers resistance to tobramycin, kanamycin, and amikacin. The aac(6')-Ib-cr variant gene can induce resistance against aminoglycoside and fluoroquinolone simultaneously. Two main methods, sequence analysis and the restriction enzyme method, can detect the aac(6')-Ib-cr variant in clinical strains. ...
