Prisustvo bakterije Plesiomonas shigelloides u površinskim vodama Panonske nizije i izolacija i karakterizacija njenih specifičnih faga / Presence of Plesiomoas shigelloides and its corresponding bacteriophages in surface waters of the Pannonian Plain

Description

<p>U ovom radu vr&scaron;ena je izolacija sojeva<em>&nbsp; P. shigelloides</em>&nbsp; iz uzoraka povr&scaron;inskih voda<br />Panonske nizije i formirana je kolekcija kultura, nakon čega je obavljena karakterizacija<br />faktora virulencije i antibiotske rezistencije&nbsp; izolovanih sojeva. Pored toga vr&scaron;ena je<br />izolacija bakteriofaga specifičnih za vrstu <em>P. shigelloides</em> iz uzoraka povr&scaron;inskih i otpadnih voda kao i njihova karakterizacija. Karakterizacija je podrazumevala sledeće testove: ispitivanje efikasnosti lize, litičkog spektra, uticaja različitih ekolo&scaron;kih faktora,<br />određivanje proteinskog profila i karakterizaciju genoma. Pored toga, vr&scaron;ena je detekcija<br />izolovanih bakteriofaga kori&scaron;ćenjem protočnog citometra. Rezultati ovog rada su potvrdili<br />prisustvo bakterije <em>P. shigelloides</em>&nbsp; i njenih specifičnih bakteriofaga u povr&scaron;inskim&nbsp; vodama Panonske nizije. Budući da su bakteriofagi specifični za vrstu&nbsp;<em> P. shigelloides&nbsp;</em> po prvi put izolovani, rezultati ovog rada mogu predstavljajati prvi&nbsp; korak u ispitivanjima vezanim za regulaciju brojnosti ove bakterije putem primene bakteriofaga.</p> / <p>We analyzed surface waters collected in Panonian plane, for the presence of bacterium&nbsp; <em>P. shigelloides</em>. The bacterial strains were preserved and characterized for virulence factors and antibiotic resistance. In addition, isolation of&nbsp; <em>P. shigelloides</em>&nbsp; specific bacteriophages was performed. Characterization of isolated phages included the following tests: examination of lytic efficacy, lytic spectrum, the influence of various ecological factors, the determination of the protein profile and the characterization of the genome. In addition, isolated bacteriophages were detected using a flow cytometer. The results of this paper demonstrate that the surface waters of Panonian plane contain bacterium&nbsp; <em>P. shigelloides&nbsp;</em> and its specific bacteriophages. Since&nbsp; <em>P. shigelloides</em>&nbsp; &ndash;&nbsp; specific bacteriophages are for the&nbsp;first time isolated, the results of this paper can represent the first step in the studies related to the regulation of the number of this bacterium by the application of bacteriophages.</p>
