  Co-existence of heavy metals and antibiotics becomes increasingly common in environmental pollution. To investigate the stress of heavy metals on microbial resistance to antibiotics, fifty-six strains of bacteria were initially isolated from some swine water in Guangzhou city, based on their resistance to four antibiotics (cefradine, norfloxacin, amoxicillin, tetracycline) and five heavy metals (Pb2+, Cr(VI), Hg2+, Cu2+, Zn2+), a gram-negative isolate, Pseudomonas putida XX6, was selected to study the detail stress rules of heavy metals on its resistance to antibiotics. The antibiotics incidences of these isolates were in the order of norfloxacin>amoxicillin>cefradine>tetracycline, and that of P. putida XX6 was  cefradine>amoxicillin≈tetracycline>norfloxacin. The addition of heavy metals made all isolates’  resistance to antibiotics decrease,.. Read More»
