Abstract:Uvod: Mikroorganizmi so vseživljensko pomembni in prisotni v našem življenju. Poznamo patogene, komenzalne in oportunistične seve mikroorganizmov. Mnogi sevi mikroorganizmov so tudi probiotiki. Zaradi obširnosti mikroorganizmov smo se osredotočili samo na rodove Enterococcus, Streptococcus, Bacillus, Clostridioides, Escherichia in Klebsiella. Postavili smo si raziskovalna vprašanja, ki so se nam zdela ključna pri raziskovanju patogenih in probiotičnih sevov mikroorganizmov. Metode: S sistematičnim pregledom strokovne domače in tuje literature smo iskali probiotične in patogene mikroorganizme. Uporabili smo metodo PRISMA in v obliki tabel prikazali rezultate. Na podlagi pregleda literature smo po bazah podatkov pridobili 18.260 člankov, odstranili duplikate in članke analizirali glede ustreznosti. V magistrski nalogi smo vključili 62 preglednih in izvirno znanstvenih člankov, ki so vsebinsko ustrezali naši raziskovani temi. Rezultati: Ugotovili smo, da obstajajo iste taksonomsko vrste, ki imajo koristne in škodljive značilnosti. Probiotične seve uporabljajo pri zdravljenju bolezni, ki jih ob okužbah povzročajo patogeni sevi. Probiotični in patogeni sevi se razlikujejo v virulenci, toksičnosti, odpornosti na okolje z ekstremnimi pH vrednostmi, odpornosti proti antibiotikom in metabolitih. Razprava in sklep: Na podlagi rezultatov ugotavljamo, da ne moremo kategorizirat taksonomskih vrst na patogene ali probiotične mikroorganizme, zato je potrebno nujno poznavanje specifičnih lastnosti posameznih sevov mikroorganizma.

Title:Comparison between selected microorganisms: pathogenic and probiotic strains
Abstract:Introduction: Microorganisms have an important presence throughout our entire lives. They are divided into pathogenic, commensal, and opportunistic microorganisms. Many strains are also probiotic strains. In this research we focused only on the genera Enterococcus, Streptococcus, Bacillus, Clostridioides, Escherichia and Klebsiella. We prepared research questions that we thought were crucial in researching pathogenic and probiotic strains of microorganisms. Methods: We searched for probiotic and pathogenic microorganisms through a systematic review of professional and scientific domestic and international literature. We used the PRISMA method and presented the results in the form of tables. Based on the literature review, we obtained 18,260 articles from databases, then removed duplicates and analysed them for relevance. In the master's thesis, we included 62 scientific articles, which in terms of content corresponded to our research topic. Results: Our findings were that there are the same taxonomic species that share beneficial and harmful characteristics. Probiotic strains are used in the treatment of diseases caused by pathogenic strains during infections. Probiotic and pathogenic strains differ in benefits, virulence, toxicity, resistance to the environment with extreme values pH, antibiotic resistance and metabolites. Discussion and conclusion: Based on the results, we conclude that we cannot categorize taxonomic species into pathogenic or probiotic microorganisms, as not all strains within these species are probiotic or pathogenic, so it is essential to know specific characteristics of the individual strain of the microorganism.
