background and objective: diabetes mellitus is one of the main problems in health systems in the world. diabetic foot infections (dfi) is one of the main complications and the most cause of non-traumatic lower limb amputation .this study aimed to determine the prevalence of bacteria involved in dfi and their antibiotic resistance in patients with dfi diagnosis. patients and methods: this desc...
Food animals are a potential source of CTX-M resistance genes for humans. We evaluated the transfer of the bla(CTX-M-9) gene from an animal strain of Salmonella enterica serotype Virchow to Enterobacteriaceae of the human intestinal flora by using human flora-associated (HFA) rats with and without cefixime treatment. In the absence of antibiotic, no transconjugant enterobacteria were found in t...
BACKGROUND The introduction of the 7-valent conjugate pneumococcal vaccine (PCV7) in children may result in serotype replacement. We estimated the rate of increase of invasive pneumococcal disease (IPD) caused by serotype 19A in children <5 years old and determined the genetic composition of these isolates. METHODS Cases of IPD between July 1999 and June 2004 were identified through the Activ...
Klebsiella pneumoniae is one of the most important opportunistic enteric bacteria and is a major cause of pneumonia and urinary tract infection. Serotype capsules of K1 and K2 can cause intense diseases. Acquisition of plasmid that codes the production of ESBLs confers on K. pneumoniae resistance to number of broad spectrum antibiotics posing a global public health problem. Integron is one of t...
The resistance of Listeria monocytogenes to cadmium and arsenic has been used extensively for strain subtyping. However, limited information is available on the prevalence of such resistance among isolates from the environment of food-processing plants. In addition, it is not known whether the resistance of such isolates to heavy metals may correlate with resistance to quaternary ammonium compo...
BACKGROUND Salmonella is a leading cause of foodborne illness. The emergence of antimicrobial-resistant salmonella is associated with the use of antibiotics in animals raised for food; resistant bacteria can be transmitted to humans through foods, particularly those of animal origin. We identified and characterized strains of salmonella isolated from ground meats purchased in the Washington, D....
Bovine respiratory disease is a common health problem in beef production. The primary bacterial agent involved, Mannheimia haemolytica, is a target for antimicrobial therapy and at risk for associated antimicrobial resistance development. The role of M. haemolytica in pathogenesis is linked to serotype with serotypes 1 (S1) and 6 (S6) isolated from pneumonic lesions and serotype 2 (S2) found in...
سرطان نوعی بیماری است که در آن سلول ها توانایی تقسیم و رشد عادی خود را از دست می دهند ازاجتماع این سلول های سرطانی, توده ای به نام تومور ایجاد می شود. مرگ ناشی از سرطان در سال ???? ، ?/? میلیون نفر بوده است که ??%از کل ?? میلیون مرگ در سراسرجهان رابه خوداختصاص میدهد. سرطان کلورکتال که به نام های سرطان کلون یا روده نیز خوانده می شود، در پی رشد سلول های سرطانی در کولون، رکتوم و آپاندیس بروز می...
Salmonella enterica serotype Typhimurium is a food-borne pathogen that also selectively grows in tumours and functionally decreases P-glycoprotein (P-gp), a multidrug resistance transporter. Here we report that the Salmonella type III secretion effector, SipA, is responsible for P-gp modulation through a pathway involving caspase-3. Mimicking the ability of Salmonella to reverse multidrug resis...
conclusion prevalence of p. aeruginosa producing esbl and mdr strains from our clinical samples and environment is still low. results the highest resistance rates from the isolated p. aeruginosa were shown against piperacillin, imipenem, cefotaxime, ceftriaxone, gentamicin, ceftazidime, aztreonam, and ciprofloxacin, respectively. seven isolates (9.2%) were esbl producers. more than 30% of the i...
