MorphoCol : a powerful tool for the clinical profiling of pathogenic bacteria

Pathogenicity, virulence and resistance of infection-causing bacteria are noteworthy problems in clinical settings, even after disinfection practices and antibiotic courses. Although it is common knowledge that these traits are associated to phenotypic and genetic variations, recent studies indicate that colony morphology variations are a sign of increased bacterial resistance to antimicrobial agents (i.e. anti...

Relevance of porin OprE on adaptive resistance of Pseudomonas aeruginosa biofil...

Biofilm formation is a phenomenon that happens naturally in the environment, representing one of the strategies adopt by microorganisms in attempt to protect themselves from external pressures. In clinical area, the most common practice to eliminate unwanted biofilms is the application of antimicrobial agents. However, current disinfection practices show often inefficacy in the eradication of biofilms, contribu...

Adaptive response of single and binary biofilms formed in the presence of benza...

In actual situations bacteria can live nicely in hostile environments in part due to its ability to live in biofilms and to regulate gene expression as an adaptive response to a variety of stresses. This altered profile, compared to planktonic counterparts, as well as the interactions amongst the several strains existing within the biofilm seems to be responsible for the gradual loss of susceptibility to antimi...
