dc.description.abstract | Soj Enterococcus faecalis BGPT1-10P je izolovan iz domaćeg polutvrdog sira, poreklom sa Stare Planine. Rezultati pokazuju da soj BGPT1-10P sintetiše termolabilan bakteriocin, enterolizin A, sa širokim spektrom delovanja, uključujući patogene bakterije roda Listeria i Candida. EntL gen, odgovoran za sintezu ovog bakteriocina, je hromozomalno lokalizovan. Analiza nukleotidne sekvence entL gena kod prirodnog izolata En. faecalis BGPT1-10P je identična sa entL genom soja En. faecalis LMG 2333, koji je prethodno okarakterisan. Pokazana je jedinstvena sekvenca entL gena i njegove okoline, koju čine orf1, orf2 i orf3 geni, kao i scpE gen. Prvi put je kod prirodnog izolata okarakterisan scpE gen, koji kodira virulentni faktor stafopain peptidazu. Funkcionalna analiza entL gena je pokazala da je kompletna genetička informacija, neophodna za sintezu i aktivnost enterolizina A, sadržana u entL genu. Soj BGPT1-10P osim enterolizina, sintetiše i želatinazu i citolizin i sadrži set različitih virulentnih faktora. Pored toga, BGPT1-10P nosi ermB i tetM gene, odgovorne za rezistenciju na eritromicin i tetraciklin. | sr |
dc.description.abstract | Strain Enterococcus faecalis BGPT1-10P was isolated from artisanal semi-hard homemade cheese from Stara Planina, Serbia. Results showed that BGPT1-10P synthesized a heat labile bacteriocin with a broad spectrum of activity, including Listeria and Candida species. Further analysis revealed that synthesized bacteriocin is enterolysin A. Moreover, the entL gene encoding enterolysin A was found to be located on the chromosome. The entL gene was cloned and sequenced. Analysis of nucleotide sequence showed that the entL gene in natural isolate En. faecalis BGPT1-10P is identical to that of the entL gene described previously in En. faecalis LMG 2333. Within the cloned DNA fragment containing the entL gene, four ORFs were detected. One of them was identified as the scpE gene, which encodes a virulent factor staphopain peptidase. Functional analysis of the entL gene showed that the complete genetic information necessary for the synthesis of enterolysin A were directly linked solely to it. Strain BGPT1-10P also synthesized gelatinase and citolysin, and contained a set of virulent factors. In addition, BGPT1-10P carries the ermB and tetM genes conferring the resistance to erythromycin and tetracycline, respectively. | en |
