Özet

This study aimed to investigate the presence of resistance genes in multidrug-resistant A. baumannii isolates as well as to determine the antibacterial activity of selected plant extracts against isolates. 41 strains were isolated from various clinical samples. PCR tests were performed using the primers. Methanol was used as solvent for the preparation of the plant extracts. MIC values of the plant extracts were determined by the broth microdilution method. The bla(OXA-)(23), bla(CTX-M-1), bla(CTX-M-2), bla(GES) genes and Class 1 integrons were detected in five isolated strains. The lowest MIC value (2.25 mg/mL) was determined for the Echinacea putpurea extract, while the highest MIC value (50 mg/mL) was determined for the Morus alba extract. Determination of the antibacterial effect of plants extracts used in the study against A. baumannii isolates shows the importance of screening the antibacterial activity of plants in the fight against antibiotic resistance.
Studiul a avut ca scop investigarea genelor de rezisten?? ale izolatelor de A. baumannii multirezistente, precum ?i determinarea activit??ii antibacteriene a unor extracte vegetale supra a 41 specii microbiene izolate din diferite probe clinice. Metanolul a fost folosit ca solvent de extrac?ie. Valorile concentra?iei minime inhibitorii ale extractelor ob?inute au fost determinate prin metoda microdilu?iei. Genele blaOXA-23, blaCTX-M-1 , blaCTX-M2 ?i blaGES, al?turi de integroni din clasa 1 au fost decelate pentru 5 specii izolate. Valoarea MIC cea mai sc?zut? (2,25 mg/mL) a fost ob?inut? pentru extractul din Echinaceea purpurea, în timp ce cea mai mare valoare MIC (50 mg/mL) a fost determinat? pentru extractul de Morus alba. Determinarea efectului antibacterian ale extractelor vegetale împotriva izolatelor de A. baumannii arat? importan?a screeningului activit??ii antibacteriene a plantelor în lupta împotriva rezisten?ei la antibiotice.
