ABSTRACT The antibiotic resistances of 45 lactic acid bacteria strains belonging to the genera Lactobacillus , Streptococcus Lactococcus Pediococcus and Leuconostoc were investigated. objective was determine verify these at genetic level, as is currently suggested by European “qualified presumption safety” safety evaluation system for industrial starter strains. In addition, we sought pinpoint possible problems in resistance determinations. Primers used PCR amplify genes involved β-lactam...

ABSTRACT The incidence of virulence factors among 48 Enterococcus faecium and 47 faecalis strains from foods their antibiotic susceptibility were investigated. No strain was resistant to all antibiotics, for some strains, multiple resistances observed. Of E. 10.4% positive one or more determinants, compared 78.7% strains. Strains exhibiting traits not necessarily traits; thus, the may be considered specific.

A taxonomic study was conducted to clarify the relationships of two bacterial populations belonging genus Weissella. total 39 strains originating mainly from Malaysian foods (22 strains) and clinical samples humans (9 animals (6 were analysed using a polyphasic approach. The methods included classical phenotyping, whole-cell protein electrophoresis, 16S 23S rDNA RFLP (ribotyping), determination sequence homologies DNA-DNA reassociation levels. Based on results, considered represent different...
