enterohemorrhagic escherichia coli (ehec), such as e. coli o157:h7, are emerging food-borne pathogens worldwide. this micro-organism can damage the epithelial tissue of the large intestine. the cytotoxic effects can be neutralized by probiotics such as bifidobacterium bifidum. probiotics are viable cells that have beneficial effects on the health of the host. the preventing activity of b. bifid...

Resistance to oxyimino cephalosporins antibiotics in Enterobacteriaceae is primarily done by the extended spectrum β-lactamases (ESBLs). Clear identification of risk factors for ESBL-producing infections is necessary. Therefore, efficient strategies can be developed to decrease outbreak of these infections. The aim of this study was to determine the antibacterial susceptibility and ESBLs patter...

Background and purpose: Escherichia coli is the most prevalent etiologic agent of urinary tract infection. Enzymatic inactivation of aminoglycosides by aminoglycoside-modifying enzymes is the main mechanism of resistance to these antibiotics in E. coli. The aim of this study was detecting the ant(2′′)-Ia gene among aminoglycoside resistant clinical isolates of E. coli using PCR method. Materia...

  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 Stx...

penicillin acylase (ec 3.5.1.11) has been a target of study for a long time because of its pivotal role in the deacylation of the penicillin into the 6- aminopenicillanic acid (6-apa) and the side-chain organic acids. this property of penicillin acylase has been exploited commercially for large scale production of 6-apa, which is the key intermediate in the manufacture of semi-synthetic penicil...

patients and methods in this cross-sectional study, a total of 250 isolates (134 e. coli and 116 k. pneumoniae) were collected and antimicrobial resistances to ampicillin, amoxicillin-clavulanic acid, amikacin, gentamycin, ceftriaxone, ceftazidime, ciprofloxacin and imipenem were evaluated by disc diffusion method and confirmed by e-test. moreover, risk factors for mdr e. coli and k. pneumoniae...

Background: Pseudomonas protein expression in E. coli is known to be a setback due to signifi cant genetic variation and absence of several genetic elements in E. coli for regulation and activation of Pseudomonas proteins. Modifi cations in promoter/repressor system and shuttle plasmid maintenance have made the expression of stable and active Pseudomonas protein possible in bot...
