title: Microwave sterilization of enterobacteria.
abstract: A new method is described which makes it possible to treat metal materials with microwaves. In consequence scalpel blades as well as cover glasses contaminated with four species of bacteria (Salmonella typhi, Proteus mirabilis, Escherichia coli and Pseudomonas aeruginosa) were sterilized. With this method sterilization can be achieved quite rapidly (1.5-2 min). Scanning electron microscopy revealed a progressive alteration in the morphology of micro-organisms and this proved proportional to the microwave exposure time. Only in Proteus mirabilis were no modifications found, even after long periods of microwave exposure.
