Many bacteria form complex multicellular communities known as biofilms. While biofilms are a common cause of human infections, they can also have productive roles in ecology and agricultural settings. In contrast to the importance of these communities, less is known ...
Bacterial biofilms are sticky and slimy substances composed of extracellular biopolymers used by bacteria for surface attachment and protection from harsh environments. Depending on the bacterial strain and the growth conditions, the biofilm composition can vary, resulting in a wide range of mechanical an...
In fact, biofilms can withstand doses up to 1,000 times greater than their planktonic counterparts. See: “Inside Versus Out: A New Form of Bacterial Cooperation” Within the biofilm, bacteria take on different responsibilities. Some individuals focus on reproduction to expand the colony, while...
aThe cultural morphology of biofilm-forming bacteria is usually different from those strains which do not form biofilms. It has been observed that biofilm-forming bacteria attach themselves to solid surfaces by using their sticky appendages and employing a rolling motion, which results in their ...
It is interesting to note that thermophilic bacteria adapted to high temperature may be subject to selection favouring smaller cell size. This may aid attachment to biofilms which provide some protection against temperature stress. 4.9. The importance of prior non-specific binding in taking some of ...
Thus, sharing carbohydrate-binding specificities with several enteropathogenic bacteria corroborated the hypothesis that selected probiotic bacteria strains could be able to compete with enteropathogens for the same carbohydrate receptors in the gut. Notably, Lactobacillus and Bifidobacterium species do not ...
on the Staphylococcus aureus (Staph) bacteria. Staph infections have an estimated mortality rate in the US of over 25%, and as much as 40% for drug-resistant strains. The researchers developed two specific tweezers that bind and either disrupt biofilm formation or bre...
Research has shown that some bacteria, includingP. aeruginosa, have evolved different strategies to respond to and cope with the low-oxygen conditions in biofilms. Communities of bacteria can, for example, change the overall structure of the biofilm so that its surface area-to-volume ratio is hi...
How do bacteria sense and interact with micro and nanotopographies? And how can this help future design? • What do preclinical studies of topographic surfaces on implants tell us? • What are the unique biocompatibility considerations for topographic surfaces? • How can laboratory testing bett...
Microbes are better equipped to break down tough plant matter than other types of decomposers. Bacteria form colonies, known as biofilms, with other bacterial species, fungi and algae. Living in a biofilm provides protection and allows sharing of nutrients and genetic material. Biofilms start the ...
