background and objectives: methicillin resistance staphylococcus aureus (mrsa) and coagulase negative staphylococci (mrcons) have recognized as the major cause of nosocomial infections that threat the burn patient’s life. the aims of this study were to determine the frequency of mrsa and mrcons and their antibiotic resistance patterns among burn patients in a burn center in ahvaz, iran. materia...

background: reduced susceptibility of clostridium difficile to antibiotics is problematic in clinical settings. there is new evidence indicating the cotransfer of toxin-encoding genes and conjugative transposons encoding resistance to antibiotics among different c. difficile strains. to analyze this association, in the current study, we evaluated the frequency of toxigenic c. difficile among th...

the aim of this study was to isolate, identify and determine the antimicrobial susceptibility of clostridium perfringens (cp) isolates from acute necrotic enteritis of broiler chickens. all broiler carcasses diagnosed as necrotic enteritis (ne) were sampled, subjected to microbial tests and 40 isolates were identified according to standard procedures. the antimicrobial susceptibility of cp isol...

conclusions this study detected multiple drug resistance (mdr) in p. aeruginosa including aminoglycosides. therefore, identification of drug resistance patterns in p. aeruginosa is of great importance in prevention and control of infections in burn patient centers. background the prevalence of resistance to aminoglycosides among p. aeruginosa isolates has increased all around the world. the res...

antimalarial drugs with the 4-aminoquinoline scaffold such as the important drugs, chloroquine (cq) and amodiaquine (aq), have been used to prevent and treat malaria for many years. the importance of these drugs is related to their simple usage, high efficacy, affordability, and cost-effectiveness of their synthesis. in recent years, with the spread of parasite resistance to cq and cross-resist...

nowadays the most difficult problem in treatment of bacterial infections is the appearance of resistant bacteria to the antimicrobial agents so that the attention is being drawn to other potential targets. in view of the positive findings of phage therapy, many advantages have been mentioned which utilizes phage therapy over chemotherapy and it seems to be a promising agent to replace the antib...

a hundred and five strains of salmonella havana were studied from the patients of pediatric hospital of tehran and tabriz during 1976-86. the sources of the strains in order to their frequency were from-stool, blood, spinal, fluid, wound and urine. from the epidemiological point of view salmonella havana is serotype of most non-typhoid salmonella. all of the strains had drug resistancy and most...

acinetobacter lwoffii, an important nosocomial pathogen, is a gram-negative aerobic bacillus that is a component of the normal flora on the skin, oropharynx, and perineum of about 20-25% of healthy individuals. we herein present a case of a 66-year-old man with combined mitral and aortic valve endocarditis associated with multi-drug resistance acinetobacter lowffii bacteremia.
