Sažetak
Pseudomonas aeruginosa is a Gram-negative aerobic bacterium that is widespread in waters of the environment. It is an opportunistic pathogen easily surviving unfavourable living conditions, such as a lack of nutrients. According to the ordinances in force, this bacterium must not be present in drinking water, finished products or waters for bathing and recreation. The objective of our research was to determine whether there were differences in survival of this bacterium with regard to the water type from which it was isolated. 10 P. aeruginosa isolates were selected from different water samples to test their survival in distilled water during 28 days. All isolates survived during the testing period. The isolate from a ship tank that was multiply disinfected with a chlorine solution had the highest survival rate whereas the isolate from the Cetina River’s brackish water had the lowest survival rate. According to the antibiotic resistance profile, it was determined that exactly this isolate, together with the one from wastewater, had an unusual resistance phenotype that makes these two isolates closer to clinical strains. The new insights into bacterial survival in unfavourable living conditions are invaluable in identifying efficient methods for their suppression.
