Plasmid-Mediated β-Lactam Resistance of Escherichia Coli Isolated from Travellers' Diarrhoea in the Far East

Abstract
The transfer of drug resistance and β-lactamase activity of 28 E. coli from travellers' diarrhoea were examined. Plasmid-mediated β-lactam resistance was found in 18 and at least 3 different types of β-lactamases were demonstrated.
