Bacteria utilise a sophisticated chemical communication system, known as quorum sensing, to assess their population density and coordinate group behaviours, including the formation of biofilms. This ...

BUFFALO, N.Y. -- University at Buffalo scientists have discovered a promising new drug lead that works by inhibiting the sophisticated bacterial communication system called quorum sensing. The new ...

The Lab Report: Every week, the Lab Report takes a deep dive into the (research) lives of students and professors outside the classroom. When a population of bacteria is large enough, individual ...

Bacteria grow on surfaces in complex immobile communities known as biofilms, which are composed of cells embedded in an extracellular matrix. Within biofilms, bacteria often interact with members of ...

Bacteria talk to each other using N-acylhomoserine lactones (AHLs) as quorum sensing (QS) signals. This signaling allows the bacteria to control gene expression of virulence factors and biofilms once ...

ITHACA, N.Y. -- A decade after microbiologists began to suspect that many groups of bacteria can communicate -- by releasing and detecting chemical pheromones to gauge their population density -- the ...

Bacteria produce slimy biofilms to coat and protect themselves and make them less susceptible to antimicrobial drugs and chemical cleaning products. The biofilms have implications for health and ...

It has been reported that the minimum inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC) for biofilm bacteria are 10 to 1000 times higher than the corresponding values for ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 98, No. 5 (Feb. 27, 2001), pp. 2752-2757 (6 pages) The opportunistic pathogenic bacterium Pseudomonas aeruginosa ...

The focus of my research is in mathematical and computational biology with particular applications in ecology, infectious diseases, and agriculture through modeling, analysis, and simulations.

Pseudomonas aeruginosa biofilm development occurs in five stages. 1. Reversible attachment: Cells transiently affix to substratum, and surface induced gene expression results in a protein profile ...
