TL;DR: TEM, SHV-, and OXA-type beta-lactamases were studied by PCR with 124 ampicillin-resistant (AMP(r)) Escherichia coli isolates recovered from foods of animal origin and feces of humans and healthy animals as mentioned in this paper.

TL;DR: Sequencing of the MSrAPCR products from either erythromycin-susceptible, low-level-resistant, or highly resistant E. faecium strains showed that the amplicons did not correspond to the msrA gene described for Staphylococcus epidermidis but corresponded to a new putative efflux determinant, which showed 62% identity with themsrA gene at the DNA level and 72% similarity at the amino acid level.

TL;DR: High levels of resistance to trimethoprim-sulphamethoxazole and tetracycline have been found in E. coli isolates from broilers, pigs and foods, which raise important questions about the potential impact of antibiotic use in animals and the possible entry of resistant pathogens into the food chain.

TL;DR: Two new primer sets for specific amplification of bacterial 16S rDNA in wine fermentation samples without amplification of eukaryotic DNA are developed, which effectively distinguished bacterial species in wine containing mixtures of yeast and bacteria.

TL;DR: It is shown that both species are highly tolerant to stress conditions and that similarly to O. oeni strains, L. plantarum strains are of interest in beverage biotechnology.
