Sažetak

Microorganisms that cause uroinfections are the same ones that constitute the natural periurethral microbiota. These bacteria are classified as primary, secondary and doubtful pathogens, and as natural microbiota that rarely causes infections. Escherichia coli and Staphylococcus saprophyticus are primary pathogens. Secondary pathogens usually cause infections only in the presence of predisposing factors. They include other enterobacteriaceae, enterococci and Pseudomonas aeruginosa, and they are showing increasing resistance to antibiotics. Identification of bacterial species determines the breakpoint concentration of bacteria in urine that deserves further investigations. However, the final interpretation of the bacterial count in urine depends on clinical presentation. Sometimes symptoms of urinary tract infections may overlap with those of vaginitis and bacterial vaginosis. The most frequent causative agents of vaginitis are Candida and Trichomonas. Bacterial vaginosis is a misbalance of natural vaginal microbiota characterized by disappearance of lactobacilli and overgrowth of Gardnerella vaginalis, diverse anaerobic bacteria, Mycoplasma hominis, Ureaplasma urealyticum and Mobiluncus spp.
