Phenotypic variants of staphylococci and their underlying population distributions following exposure to stress.

Abstract excerpt

This study investigated whether alterations in environmental conditions would induce the formation of small colony variant phenotypes (SCV) with associated changes in cell morphology and ultra-structure in S. aureus, s. epidermidis, and S. lugdunensis. Wild-type clinical isolates were exposed to low temperature (4 °C), antibiotic stress (penicillin G and vancomycin; 0-10,000 µg mL(-1)), pH stress (pH 3-9) and...
