Synergistic Interactions in Multispecies Biofilms
Multispecies biofilms are predominant in almost all natural environments, where myriads of resident microorganisms interact with each other in both synergistic and antagonistic manners. The interspecies interactions among different bacteria are, despite the ubiquity of these communities, still poorly understood. Here, we report a rapid, reproducible and sensitive approach for quantitative scree...
متن کاملDynamic interactions of neutrophils and biofilms
BACKGROUND The majority of microbial infections in humans are biofilm-associated and difficult to treat, as biofilms are highly resistant to antimicrobial agents and protect themselves from external threats in various ways. Biofilms are tenaciously attached to surfaces and impede the ability of host defense molecules and cells to penetrate them. On the other hand, some biofilms are beneficial f...
متن کاملRecent Advances in Studies of Polymicrobial Interactions in Oral Biofilms
The oral cavity supports a complex and finely balanced consortia of microbial species, many of which co-operate within structured biofilms. These communities develop through multitudinous synergistic and antagonistic inter-species relationships. Changes in the dynamics of oral microbial populations are associated with the transition from healthy teeth and gums to dental caries, gingivitis and p...
متن کاملMicrobial biofilms: from ecology to molecular genetics.
Biofilms are complex communities of microorganisms attached to surfaces or associated with interfaces. Despite the focus of modern microbiology research on pure culture, planktonic (free-swimming) bacteria, it is now widely recognized that most bacteria found in natural, clinical, and industrial settings persist in association with surfaces. Furthermore, these microbial communities are often co...
متن کاملQuorum Sensing and Bacterial Social Interactions in Biofilms
Many bacteria are known to regulate their cooperative activities and physiological processes through a mechanism called quorum sensing (QS), in which bacterial cells communicate with each other by releasing, sensing and responding to small diffusible signal molecules. The ability of bacteria to communicate and behave as a group for social interactions like a multi-cellular organism has provided...
