    Drug Resistance of Pseudomonas spp. Strains Isolated from Water Reservoirs and Sewage Treatment Plants in Szczecin
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2019) Wrzecińska, Marcjanna; Student Research Group of Microbiology, Department of Immunology, Microbiology and Physiological Chemistry, West Pomeranian University of Technology in Szczecin
    The increasing resistance of bacteria to antibiotics has become a global problem. Among 12 most alarming bacteria, the WHO recognized carbapaneme-resistant Pseudomonas aeruginosa as resistant to carbapenems as a critical threat. These bacteria can cause nosocomial infections and are common in the natural environment, including in water used as bathing beach. For this reason, effective detection is necessary to prevent infections more effectively. The aim of this study was to determine antibiotic resistance of representatives of Pseudomonas genus isolated from the environment. Water from reservoirs located in Szczecin and an one sample of activated sludge were examined. Seven strains were selected for further studies. The basic physiological and biochemical characteristics of the genus Pseudomonas along with antibiotic resistance were examined. Mobility was assessed on Swarm Agar (Caiazza et al. 2005) and confirmed under phase-contrast microscope. Pseudomonas aeruginosa strain resistant to aztreonam was discovered among the isolates. Studies have shown that water reservoirs that are used for recreational purposes and water intake may be a reservoir of antibiotic resistant bacteria, including a carbapenem-resistant P. aeruginosa. Detection of these microorganisms could serve as a marker of water contamination that would prevent Pseudomonas infections and decrease the spreading of this bacteria among people and animals.
