Genotypic Diversity, Antibiotic Resistance and Bacteriocin Production of Enterococci Isolated from Rhizospheres / N. Klibi, N. B. Slimen, I. Fhoula, M. Lopez, K. B. Slama, D. Daffonchio, A. Boudabous, C. Torres, H. Ouzari. - In: MICROBES AND ENVIRONMENTS. - ISSN 1342-6311. - 27:4(2012), pp. 533-537. [10.1264/jsme2.ME12041]
Abstract:
This study aimed to identify and to characterize rhizospheric-derived enterococci. The results showed the prevalence
of Enterococcus faecium species (97%) vs. Enterococcus durans (3%). Susceptibility testing for antibiotics showed a
low percentage of resistance to erythromycin (3.2%) and tetracycline (11.2%), and intermediate resistance to vancomycin
(6.5%). Nevertheless, a high proportion of bacteriocin production was recorded. Furthermore, PCR detection of antibiotic
resistance and bacteriocin production-encoding genes was investigated. Pulsed-field gel electrophoresis typing (PFGE)
showed a great variability of enterococci in the rhizosphere. Moreover, mutilocus-sequence-typing analysis (MLST)
revealed the identification of three new sequence types (STs), which were registered as ST613, ST614 and ST615.
