background currently, there are evidences for the existence of diverse strains of helicobacter pylori with different levels of virulence. in other way, the most important reason of therapeutic failure is resistance to the antibiotics. objectives the aim of this study was to evaluate the relationship between h. pylori drug resistance and the presence of caga gene. patients and methods gastric bi...

conclusions it seems that besides the variety and prevalence of blatem and blactx, enormous mechanisms such as porin and leaking systems (efflux pumps) are responsible for the information of the a. baumannii resistance to disinfectants. the study on an accurate consideration of the resistance in strains and other microorganisms is advised. results in the current study, 131 a. baumannii isolates...

given the inappropriate use of antibiotics and prevalence of resistant bacteria, there is urgentneed for antibacterial drugs that have fewer side effects than antibiotics. satureja bachtiaricais a medicinal plant which had many uses in traditional medicine. in this research, the ethanolextract of leave of satureja bachtiarica is tested on coagulase-negative staphylococcus strains.materials and ...

background and objectives: infectious diarrhoeal diseases are great problem throughout the world and are responsible for considerable morbidity and mortality. shiga toxin-producing escherichia coli (stec) is a major cause of gastroenteritis that may be complicated by hemorrhagic colitis (hc) or the hemolytic uremic syndrome (hus), which is the main cause of acute renal failure in children. food...

one of the great challenges in the treatment of infectious diseases is the resistance of pathogenic bacteria against antibiotics, and antibiotic resistance to shigella is broadly observed in different parts of the world. the object of this study was to determine shigella antibiotic resistance pattern against the antibiotics such as ampicillin, amoxicillin, trimethoprim-sulfamethoxazole, chloram...

background and objectives: shigella plays an important role as a causative organism of acute gastroenteritis, in children and others. rapid emergence of antibiotic resistance warrants continuous monitoring of susceptibility pattern of bacterial isolates. we report here our findings about shigella spp. isolates and their drug resistance patterns in nepalese patients. materials and methods: the s...

antimicrobial resistance in pathogens not only in hospitals but also in the community has become an important public health problem. the aim of this study was to determine the antimicrobial resistance patterns of predominant pathogens from hospitalized and outpatients in a university hospital in tehran, iran. a total of 820 samples of common gram-negative and gram-positive bacteria were collect...

background: integrons are the major reasons of multidrug resistance (mdr) among enteropathogenic bacteria. occurrence of horizontal gene transfer between integron-carrying microorganisms and other enteric bacteria may increase the rate of emergence of integron-associated antibiotic resistance. objectives: the objective of this study was to investigate class 1 integrons among members of enteropa...

Consumer demand for affordable fish drives the ever-growing global aquaculture industry. The intensification and expansion of culture conditions in the production of several finfish species has been coupled with an increase in bacterial fish disease and the need for treatment with antimicrobials. Understanding the molecular mechanisms of antimicrobial resistance prevalent in aquaculture environ...

background and objectives: infection is the most common problem following burn injury. selection and dissemination of intrinsic and acquired resistance mechanisms increase the probability of burn wound colonization by resistant species including pseudomonas aeruginosa. multi-drug resistant pseudomonas aeruginosa has frequently been reported as the cause of nosocomial outbreaks of infection in b...
