Plasmid-Mediated Antibiotic-Resistant Pattern of <i>Lactobacillus</i> spp. Isolated From Dairy Products

Background: Microorganisms have potent activity for transferring antibiotic-resistant genes with either chromosomally- or plasmid-mediated characteristics. The purpose of this study was to isolate Lactobacillus from different commercial products and evaluate their potential in development. Chromosomally-or resistant were investigated as well. Methods: In total, strains isolated 20 dairy product samples such cheese yoghurt. isolates phenotypic molecularly identified properties assessed by the disk-diffusion method. Finally, antibiotic characters evaluated plasmid curing via temperatures acridine orange methods. Results: Five paracasei, L. rhamnosus, casei, plantarum, fermentum products. results susceptibility assay indicated that all susceptible amoxicillin imipenem ciprofloxacin vancomycin. Furthermore, responses observed among against streptomycin gentamicin. evaluation resistance revealed gentamicin-resistant type rhamnosus plantarum strains. Conclusions: general, our finding demonstrated some harboured genes. These can be located chromosome group. Hence, frequency pathogenic bacteria might increased after consuming because horizontal transfer antibiotic-resistance bacteria.
