Silver-resistant Enterobacteriaceae from hospital patients.

摘要: The inclusion of agar medium containing 0.5 mM AgNO3 in the hospital laboratory replicaplating system for routine antibiotic-susceptibility determinations resulted identification species Enterobacteriaceae (Escherichia coli, Enterobacter cloacae, Klebsiella pneumoniae, Protens mirabilis, and Citrobacter freundii) with silver resistance. Since study began October. 1975, 11 in-hospital patients receiving sulfadiazine burn wound prophylaxis have yielded silver-resistant bacteria from their infected burns. During this treatment burn-site cultures these 230 isolates Enterobacteriaceae, including 211 which were sulfonamide-resistant, 97 also silver-resistant, 38 untested resistance.Seven but sulfonamide-sensitive incidentally recovered respiratory specimens four nonburn tracheostomy tubes, one isolate was recov...
