Newest firstListeria monocytogenes (LM) is a major foodborne pathogen causing illnesses ranging from gastroenteritis to severe systemic infections. The key virulence factors include bacterial motility, hemolysin and lecithinase production, and invasion of host tissues. This study investigated the anti-virulence effects of cannabidiol (CBD), the main non-psychoactive compound in Cannabis sativa, against LM. The minimum inhibit…
Open article record in new tab ↗Background Hemin is a major source of iron for pathogens in infectious niches. The FecIRA-like surface signaling cascade is a common regulatory system for iron acquisition by pathogens. This system consists of a FecA-like TonB-dependent transporter (TBDT), a FecR-like inner membrane anti-sigma factor, and a FecI-like extracytoplasmic function (ECF) sigma factor. Beyond iron acquisition, FecIRA-like systems have be…
Background Bacterial populations communicate through the cell density-dependent mechanism of quorum sensing (QS). Vibrio harveyi, one of the best studied model organisms for QS, was used to explore effects of the synthetic cannabinoid HU-210 on QS and different QS-regulated physiological processes in bacteria. Results Analysis of QS-regulated bioluminescence in wild-type and mutant strains of V. harveyi revealed t…
Open article record in new tab ↗Bacterial populations co-ordinate gene expression collectively through quorum sensing (QS), a cell-to-cell communication mechanism employing diffusible signal molecules. The LysR-type transcriptional regulator (LTTR) protein PqsR (MvfR) is a key component of alkyl-quinolone (AQ)-dependent QS in Pseudomonas aeruginosa. PqsR is activated by 2-alkyl-4-quinolones including the Pseudomonas quinolone signal (PQS; 2-hept…
