Streptococcus suis, a major porcine pathogen, has been receiving growing attention not only for its role in severe and increasingly reported infections in humans, but also for its involvement in drug resistance. Recent studies and the analysis of sequenced genomes have been providing important insights into the S. suis resistome, and have resulted in the(More)
BACKGROUND An increase in erythromycin resistance rates among group A streptococci has been reported in some European countries. These bacteria, long thought to be extracellular pathogens, can be efficiently internalised by, and survive within, human cells of respiratory-tract origin. Macrolide antibiotics enter eukaryotic cells, whereas beta-lactams are(More)

In the present study, we have evaluated the in vitro antibacterial activity of essential oils from Origanum vulgare, Thymus vulgaris, Lavandula angustifolia, Mentha piperita, and Melaleuca alternifolia against 32 erythromycin-resistant [Mininum Inhibitory Concentration (MIC) ≥1 μg/mL; inducible, constitutive, and efflux-mediated resistance phenotype; erm(TR),(More)
OBJECTIVES The study was undertaken to investigate vancomycin-resistant (vanA) Enterococcus faecalis isolates carrying aggregation substance (AS) gene(s) for their ability to co-transfer vanA and AS genes. METHODS Six vanA clumping-positive E. faecalis isolates (five human and one food sample) carrying one or more AS genes (prgB, asa1, asa373) were(More)
Capsaicin (8-methyl-N-vanillyl-6-nonenamide) is the active component of Capsicum plants (chili peppers), which are grown as food and for medicinal purposes since ancient times, and is responsible for the pungency of their fruit. Besides its multiple pharmacological and physiological properties (pain relief, cancer prevention, and beneficial cardiovascular,(More)
Dental plaque is a complex multispecies biofilm consisting of a dense community of interacting bacteria (*10 10 cells/ mg) embedded in a self-produced polysaccharide matrix [1, 4]. Plaque control is critical for oral health, since plaque bacteria include pathogens involved in both dental caries and periodontal disease—the most prevalent human microbial(More)
T he unprecedented wealth of databases that have become available in the era of next-generation sequencing has considerably increased our knowledge of bacterial genetic elements (GEs). At the same time, the advent of single-cell based approaches has brought realization that unsuspected heterogeneity may occur in the bacterial population from a single(More)
