Biochemical Detection of N-Acyl Homoserine Lactone from Biofilm-Forming Uropathogenic Escherichia coli Isolated from Urinary Tract Infection Samples
Background: N-Acyl homoserine lactone (AHL) is found to be the main component of quorum sensing (QS) in Gram-negative bacteria and plays an important role in biofilm formation. Little information is available regarding the role of AHL in biofilm formation in Escherichia coli (E. coli). The purpose of this investigation was to biochemically detect and characterize AHL activity in biofilm-forming...
متن کاملEvaluation of biofilm-forming capabilities of urinary Escherichia coli isolates in microtiter plate using two different culture media
The ability of uropathogenic E. coli (UPEC) to cause symptomatic UTI is associated with the expression of a variety of virulence factors. Biofilm formation enables UPEC to resist the flow of urine and increases its tolerance to antimicrobials and the host immune response. The measurement of biofilm formation in vitro is affected by the type of culture medium used. The aim of this study was to e...

متن کاملClonal Relatedness of Enterotoxigenic and Enteropathogenic Escherichia coli Isolates from Diverse Human, Foods and Calf Sources
Background: Foodborne infection caused by EnterotoxigenicEscherichia coli (ETEC) and Enteropathogenic Escherichia coli (EPEC) is one of the major health problems, particularly in the developing countries. Therefore, it is vital to identify the origin of food contamination to plan control strategies efficiently. Method: A tota...
متن کاملEmergence of biofilm-forming subpopulations upon exposure of Escherichia coli to environmental bacteriophages.
Exposure of Escherichia coli MG1655 to environmental bacteriophages results in rapid selection for phage-tolerant subpopulations displaying increased biofilm formation. Analysis of one phage-tolerant strain revealed large amounts of the DNA-binding Dps protein in the outer membrane protein and production of fimbria-like structures. In dps and fimA mutant derivatives of MG1655, no selection of p...
