This study was carried to estimate the bacterial load and the presence of five enterotoxigenic bacterial pathogens included Salmonella spp., Listeria monocytogens, Bacillus cereus, Escherichia coli O157:H7 and Clostridium perfringens using multiplex polymerase chain reaction (M-PCR) on dried spices and herbs retailed in Saudi Arabia. The study further aimed to analyze antibiotic resistance rate...
Antimicrobial Resistance to Ceftazidime and Ceftriaxone, and Detection of TEM Gene in Esherchia Coli
Abstract Background and Objective: In the past, most strains of E. coli were susceptible to a wide range of antimicrobial agents, but this situation is now changed by indiscriminate use of antibiotics. Ceftriaxone and Ceftazidime are the most current antibiotics used for Enterobacteriaceae infections in hospitals. The aim of this study was to determine antimicrobial resistance of Escherichia co...
background and objective: constant use of limited number of lactic acid bacteria species in biopreservation can cause genetic degradation and or rising resistance against food pathogens or antimicrobial substances they produce. for this objective, a newly isolated strain of lactobacillus acidophilus possessing high antimicrobial activity was evaluated as a candidate for use in biopreservation. ...
Background & Objectives: Escherichia coli is the most common agent of urinary tract infections, with P fimbriae as the most important virulence factor. Uropathogenic Escherichia coli expresses various types of adhesive genes such as P fimbriae and pyelonephritis-associated pili (PAP), which mediate the binding to the surface of epithelial cells in the urinary tract. This study aimed to iden...
escheric hia coli o157:h7 lives in the intestines of healthy cattle, and can contaminate meat during slaughtering pr actices . detection of the low infectious dosage of bacterium requires a sensitive method. we developed polymerase chain reaction (pcr) assays to detect the gene stx2 irrespective of the bacterial serotype. in this study, the detection limit of the pcr protocol in detecting stx2 ...
Enterohemorrhagic Escherichia coli (EHEC) with serotype O157:H7 is a major foodborne pathogen. Here, we report the draft genome sequence of EHEC O157:H7 strain MC2 isolated from cattle in France. The assembly contains 5,400,376 bp that encoded 5,914 predicted genes (5,805 protein-encoding genes and 109 RNA genes).
A population-based study combining (i) antimicrobial, (ii) genetic, and (iii) virulence analyses with molecular evolutionary analyses revealed segregative characteristics distinguishing human clinical and bovine Escherichia coli O157 strains from western Canada. Human (n = 50) and bovine (n = 50) strains of E. coli O157 were collected from Saskatchewan and Manitoba in 2006 and were analyzed by ...
Escherichia coli O157:H7 (E. coli O157:H7) is one of the top pathogens of interest for the development of rapid diagnostic systems for food and water samples. The objective of this research is to develop a rapid, novel electrochemical biosensor based on the use of polypropylene microfiber membranes coated with a conductive polypyrrole and antibody functionalized for the biological capture and d...
