Assessment of environmental factors associated with biofilm formation in shiga toxin producing escherichia coli with their role in colonization

Maroof Malik

Shiga Toxin Producing Escherichia coli (STEC) is grown sky lighted last a few years and researchers concluded that STEC (Shiga Toxin Producing Escherichia coli) are liable for producing biofilms. Biofilms are aggregates of microbial cells at interfaces like Solid-Liquid, Liquid-Liquid, & Liquid-Gaseous. It's almost ubiquitous in nature; however, Most Microorganisms live together in large communities attached to a surface. A biofilm is an assemblage of surface-associated microbial cells that's enclosed in an extracellular polymeric substance matrix which is additionally mentioned as slime. A mature biofilm can contain as many 100 billion bacterial cells per milliliter. STEC (Shiga Toxin Producing Escherichia coli) are capable of forming biofilms on different food or food contact surfaces. Antony Van Leeuwenhoek, using his simple microscopes, first observed microorganisms on tooth surfaces and may be credited with the invention of microbial biofilms. Samples of Microbial species that form Biofilms are Escherichia coli, Staphylococcus aureus, Listeria monocytogenes, Pseudomonas aurogenosa, Campylobacter spp., Salmonella typhimurium, Vibrio cholerae. Biofilm causes numerous chronic infections, like chronic osteo- myelitis, chronic cystitis, chronic prostatitis, and chronic pneumonia in patients with CF.
