ZnuA and zinc homeostasis in Pseudomonas aeruginosa
Pseudomonas aeruginosa is a ubiquitous environmental bacterium and a clinically significant opportunistic human pathogen. Central to the ability of P. aeruginosa to colonise both environmental and host niches is the acquisition of zinc. Here we show that P. aeruginosa PAO1 acquires zinc via an ATP-binding cassette (ABC) permease in which ZnuA is the high affinity, zinc-specific binding protein....
متن کاملInteractions between Neutrophils and Pseudomonas aeruginosa in Cystic Fibrosis
Cystic fibrosis (CF) affects 70,000 patients worldwide. Morbidity and mortality in CF is largely caused by lung complications due to the triad of impaired mucociliary clearance, microbial infections and chronic inflammation. Cystic fibrosis airway inflammation is mediated by robust infiltration of polymorphonuclear neutrophil granulocytes (PMNs, neutrophils). Neutrophils are not capable of clea...
متن کاملPossibility of novel therapeutic strategy for multidrug resistant Pseudomonas aeruginosa using bactericidal activity in Streptococcus sanguinis secretion
Multidrug-resistant Pseudomonas aeruginosa (MDRP) infection has become a serious clinical problem in the currently. We reported the bactericidal activity in the filtrated supernatant of Streptococcus (S.) sanguinis against P. aeruginosa. The S. sanguinis, isolated from the sputum of a pulmonary-disease patient, was cultured for overnight, and filtered supernatant was tested for bactericidal eff...
متن کاملInterbacterial adherence between Actinomyces viscosus and strains of Streptococcus pyogenes, Streptococcus agalactiae, and Pseudomonas aeruginosa.
Interbacterial adherence was sought between strains of Actinomyces viscosus indigenous to the human mouth and strains of Streptococcus pyogenes, Streptococcus agalactiae, and Pseudomonas aeruginosa. Six of nine strains of S. pyogenes, three of five strains of S. agalactiae, and two of four strains of P. aeruginosa were found to coaggregate with each of five strains of A. viscosus tested. Some c...
متن کاملCompetition and coexistence between Streptococcus mutans and Streptococcus sanguinis in the dental biofilm.
The human mucosal surface is colonized by the indigenous microflora, which normally maintains an ecological balance among different species. Certain environmental or biological factors, however, may trigger disruption of this balance, leading to microbial diseases. In this study, we used two oral bacterial species, Streptococcus mutans and Streptococcus sanguinis (formerly S. sanguis), as a mod...
