DNA-based PCR Test Accurately Predicts Antibiotic Resistance

According to a study published in Antimicrobial Agents and Chemotherapy, the researchers evaluated more than 7,500 highly antibiotic-resistant clinical isolates of Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis and Pseudomonas aeruginosa for antibiotic-resistance genes and compared them with phenotypic resistance across penicillins, cephalosporins, carbapenems, aminoglycosides, trimethoprim-sulfamethoxazole, fluoroquinolones and macrolides.
