Does Streptococcus mitis, a neonatal oropharyngeal bacterium, influence the pathogenicity of Pseudomonas aeruginosa?

摘要: Microorganisms in a biofilm might promote or suppress each other. We previously found that Pseudomonas aeruginosa (P. aeruginosa) and the normal colonized bacteria oropharynx, Streptococcus mitis (S. mitis), were most common on newborns' endotracheal tubes. Here, we S. enhanced adhesion formation of P. aeruginosa. Furthermore, it alleviated immune response induced by These findings remind us should not ignore role traditionally viewed non-pathogenic biofilms provide new insights into exploring bacterial interaction mechanisms related infections.
