Antibiotic Resistance in Lactobacillus reuteri and Lactobacillus plantarum
Lactic acid bacteria (LAB) may act as reservoirs of antibiotic resistance genes that can be transferred via the food chain or within the gastrointestinal tract to pathogenic bacteria. This thesis provides data required for assessing the potential risk of using antibiotic resistant strains of the LAB species Lactobacillus reuteri and Lactobacillus plantarum as food processing aids or probiotics....
متن کاملProbiotic Properties of Lactobacillus Species Isolated from Local Traditional Fermented Products
The present study aims to isolate Lactobacillus species from locally fermented vegetables and to characterize selected isolates for their probiotic potential. Seventeen Lactobacillus strains (9 Lactobacillus plantarum 1, 3 Lactobacillus pentosus, 2 Lactobacillus brevis 1, 2 Lactobacillus brevis 3 and 1 Lactobacillus salivarius) were isolated and tested for their probiotic potential. This includ...
متن کاملIsolation and study on the technological and probiotic characterization of Lactobacilli in traditional white Lighvan cheese
Background: Probiotics and especially Lactobacilli are among the most important components widely used in food technology. Isolation and characterization of indigenous probiotics should be performed in native populations. OBJECTIVES: In order to isolate lactobacillus spp. from Iranian traditional Lighvan cheese to be used as starters, 15 cheese samples were randomly selected and tested for tech...
متن کاملIncompatibility of Lactobacillus Vectors with Replicons Derived from Small Cryptic Lactobacillus Plasmids and Segregational Instability of the Introduced Vectors.
Three new Lactobacillus vectors based on cryptic Lactobacillus plasmids were constructed. The shuttle vector pLP3537 consists of a 2.3-kb plasmid from Lactobacillus pentosus MD353, an erythromycin resistance gene from Staphylococcus aureus plasmid pE194, and pUC19 as a replicon for Escherichia coli. The vectors pLPE317 and pLPE323, which do not contain E. coli sequences, were generated by intro...
متن کاملPlasmid profiles and transfer of plasmid-encoded antibiotic resistance in Lactobacillus plantarum.
Plasmids were visualized in strains of Lactobacillus plantarum by use of a rapid method. Plasmids pIP501 and pAM beta 1 were transferred by conjugation from Streptococcus strains to Lactobacillus plantarum, and recipient strains were shown to act as donors in crosses to S. lactis. Attempts to transfer these plasmids between strains of L. plantarum were not successful.
