Antibacterial and antibiofilm effects of essential oil components, EDTA and HLE disinfectant solution on , and sp. multiresistant strains isolated along the meat production chain.

The spread of multidrug resistant (MDR) bacteria and resistance genes along the food chain and the environment has become a global, but silent pandemic. To face this challenge, it is of outmost importance to develop efficient strategies to reduce potential contamination by these agents. In the present study, 30 strains of sp.

Transcriptomic Profile and Probiotic Properties of Pre-adapted to Edible Oils.

In this study, we determined whether pre-adapting strains, isolated from Aloreña green table olives, to vegetable-based edible oils improved their robustness and functionality; this may have great importance on their stress response during fermentation, storage, and digestion. Pre-adapting the strains to the corresponding oils significantly increased their probiotic functionality (e.g.

Insight into Potential Probiotic Markers Predicted in MP-10 Genome Sequence.

MP-10 is a potential probiotic lactic acid bacterium originally isolated from naturally fermented Aloreña green table olives. The entire genome sequence was annotated to analyze the molecular mechanisms involved in the adaptation of MP-10 to the human gastrointestinal tract (GIT), such as carbohydrate metabolism (related with prebiotic utilization) and the proteins involved in bacteria-host interactions. We predicted an arsenal of genes coding for carbohydrate-modifying enzymes to modify oligo- and polysaccharides, such as glycoside hydrolases, glycoside transferases, and isomerases, and other enzymes involved in complex carbohydrate metabolism especially starch, raffinose, and levan.

Fermented Aloreña Table Olives as a Source of Potential Probiotic Strains.

A collection of 31 strains isolated from naturally fermented Aloreña green table olives were screened in depth in the present study for their probiotic potential. Several strains could be considered promising probiotic candidates since they showed good growth capacity and survival under simulated gastro-intestinal conditions (acidic pH of 1.5, up to 4% of bile salts and 5 mM of nitrate), good ability to auto-aggregate which may facilitate their adhesion to host cells as multiple aggregates and the subsequent displacement of pathogens.

APRIL but not BLyS serum levels are increased in chronic lymphocytic leukemia: prognostic relevance of APRIL for survival.

APRIL (a proliferation-inducing ligand) and BLyS (B lymphocyte stimulator) expression have been reported in chronic lymphocytic leukemia (CLL) cells. We examined APRIL and BLyS serum levels in CLL patients and evaluated the prognostic significance of APRIL expression on survival.
