“…Transfer of antibiotic resistance from animals to humans through food products derived from animals colonized by resistant bacteria is quite possible (Gonzalez-Zorn and Escudero, 2012). However, the role of LAB as reservoir of antibiotic resistance determinants with transmission potential to pathogenic species is now increasingly acknowledged (Marshall et al, 2009;van Reenen and Dicks, 2011).…”

In the present study, a total of 56 isolates were isolated from different root vegetables. Out of these, 17 isolates were identified as Leuconostoc spp. All the 17 isolates were checked for antibiotic sensitivity against different antibiotics. Results revealed that majority of the isolates were resistant to Penicillin G, Vancomycin, Oxacillin and Ceftazidime. Four isolates (S-9, S-13, S-37 and S-42) were resistant to methicillin. However, all the isolates were highly sensitive to Imipenum. Carbenicillin and Amoxicillin sublactam showed antibacterial sensitivity against all the isolates except S-13 and S-B 2 C 2, respectively. Electrophorogram revealed that among the different 17 Leuconostoc isolates, S-B 2 C 2 showed the presence of multiple plasmids (six) corresponding to the molecular weights of 1.5, 1.9, 2.0, 2.6, 3.2 and 10 kb, respectively. Endonuclease restriction analysis study was carried out with purified plasmid using four endonucleases (Alu I, Bam HI, Hae III and Hind III). Treatment with Alu I resulted in the disappearance of all the 6 plasmid bands, indicating complete digestion of the plasmids. Restriction analysis of plasmid DNA of isolate S-B 2 C 2 revealed complete digestion of two plasmids (2.6 and 1.5 kb) when treated with Hind III. However, a new band of molecular weight equivalent to 1.7 kb did appear. Data presented in the paper indicates the multiple plasmid availability in bacteria and their diversity in response to restriction sites available on them.

“…As in the case of meats and Enterobacteriaceae, several fermented foods have recently been suggested as potential vehicles for the exchange of antibiotic resistance genes between acid lactic bacteria and other pathogens in the gastrointestinal tract [29]. As most of the Lactobacillus species isolated in this study presented resistance to both of the drugs, it will be interesting to determine in the course of future studies whether the resistance of these strains results from an intrinsic mechanism or are due to genes encoding possible transferable resistance determinants.…”

Despite increasing interest in the bacterium, the methodology for Clostridium difficile recovery has not yet been standardized. Cycloserine-cefoxitin fructose taurocholate (CCFT) has historically been the most used medium for C. difficile isolation from human, animal, environmental, and food samples, and presumptive identification is usually based on colony morphologies. However, CCFT is not totally selective. This study describes the recovery of 24 bacteria species belonging to 10 different genera other than C. difficile, present in the environment and foods of a retirement establishment that were not inhibited in the C. difficile selective medium. These findings provide insight for further environmental and food studies as well as for the isolation of C. difficile on supplemented CCFT.

“…This interesting result supposes that it could be intrinsic resistance. Contrary to the acquired resistance, the latter represents only a negligible risk of propagation [35].…”

This work aimed to characterize strains of Bacillus with fermenting properties for the production of α-amylases, proteases and pectinases and to evaluate their probiotic abilities. The detection of the fermentative enzymes of the different strains was carried out on solid media containing a specific substrate. Stress resistance of gastrointestinal transit was evaluated in vitro and the diffusion method in agar medium and antibiotic susceptibility of targeted strains was used to assess antibacterial activity. As results, evaluation of the fermentative potential revealed good proteolytic (100 %), pectinolytic (68.42 %) and amylolytic (57.90 %) activities. The evaluation of the probiotic potential also revealed promising results: resistance to gastric acid from two strains with a survival rate above 70 % at pH 2.5; a growth in the presence of 0.3 % biliary salt and an inhibitory capacity against Staphylococcus aureus, Serratia odorifera and Salmonella spp. Intrinsic resistance of the strains was observed with respect to cefoperazone and amoxicillin.
