GENETIC AND MORPHOTYPIC HETEROGENEITY OF SWIMMING POOL BACTERIAL POPULATIONS

Abstract


The populations of resident bacterial species of the swimming pool community such as Pseudomonas aeruginosa, Bacillus sp., Acinetobacter lwoffii and Pseudomonas alcaligenes were analyzed. All these species showed stable in time heterogeneity by spontaneous mutation frequency and biofilm forming ability. There was notably high occurrence of mutators in all investigated populations. Our results show high level of genetic plasticity and adaptivity under conditions of starvation and exposure to biocides.
