BACKGROUND Probiotic bacteria have a beneficial effect on intestinal inflammation. In this study, we have examined the effect of lactic acid and commensal Gram positive (+) bacteria conditioned media (CM) on tumour necrosis factor alpha (TNF-alpha) release and the mechanisms involved. METHODS Lipopolysaccharide (LPS) induced TNF-alpha secretion by peripheral blood mononuclear cells or the THP...

in the last decade, along with the problem of nosocomial infections, multidrug-resistant bacteria in community and hospitals have soared. high frequencies of multidrug-resistant bacteria have been grouped under the acronym eskape: enterococcus faecium, staphylococcus aureus, klebsiella pneumoniae, acinetobacter baumannii, pseudomonas aeruginosa and enterobacter spp. the eskape pathogens are res...

Endophytic bacteria inhabit within plant tissues without causing any evident damage to the host and play crucial roles in plant growth, development, fitness, and protection (Farrar et al., 2014; Truyens et al., 2015). These endophytic bacteria spend a portion of their life cycle inside plants and normally resides on intercellular spaces and gain carbohydrates, amino acids, and inorganic nutrien...
