background :    unfortunately, antibiotic resistance has become an increasingly critical problem in many countries like iran. since there are very few published data on antibiotics resistance in alborz province, the aim of this study was to survey the pattern of antimicrobial resistance and prevalence detection of tem-type beta-lactamases among clinical isolates of escherichia coli using univer...

The behaviour of Escherichia coli O157:H7 was studied during the manufacture and storage of Iranian white cheese in brine. Cheese was manufactured using pasteurized cow milk and inoculated with E. coli O157:H7 with inoculum level of 103 cfu/ml. Four treatments were designed. Cheeses were made with or without starter culture and kept immersed in 6 or 8% salt brine during ripening and storage. Ch...

We establish an identity for compact hyperbolic surfaces with or without boundary whose terms depend on the dilogarithms of the lengths of simple closed geodesics in all 3-holed spheres and 1-holed tori in the surface.

Using the (generalized) Darboux transformation in the case of the Clifford torus, we construct for all Pythagorean triples (p, q, n) ∈ Z a CP–family of Willmore tori in S with Willmore energy 2nπ.

background and objective: escherichia coli o157:h7, an emerging pathogen, causes severe enteritis and the extraintestinal complication of hemolytic-uremic syndrome. the goal of this study was to evaluate the conjugate of e. coli o157: h7 lipopolysaccharide (lps) with diphtheria toxoid (dt) as a candidate vaccine in mice model. material and methods: lps from e. coli o157:h7 was extracted by hot ...

conclusions tetracycline resistance is widespread among uropathogenic e. coli isolates from human infections. moreover, the distribution of tetracycline resistance determinants among the studied e. coli was very similar to the findings of the international sourced gallery of clinical e. coli strains. background uropathogenic escherichia coli is one of the most prevalent infectious agents in hum...

conclusions the high prevalence of quinolone resistance genes, which indicates antibiotic resistance, in the imam reza hospital of mashhad is a major concern. hence, the antibiotics prescription policy should be revised, and infection control measures should be improved. results eighty-six (43%) isolates were ciprofloxacin-resistant. the pct identified 85 (42.5%) of 200 e. coli isolates as esbl...

Objective(s): Antibacterial materials are so significant in the textile industry, water disinfection, medicine, and food packaging. Unfortunately, organic compounds for sterilization show toxicity to the human body; therefore, the interest in inorganic disinfectants such as metal oxide nanoparticles (NPs) is increasing. Materials and Methods: Nickel and nickel hydroxide nanoparticles (NiNPs ...
