most nosocomial infections have been attributed to nonfermenters, particularly acinetobacter baumannii which causes serious infections like pneumonia, meningitis, and sepsis. the purpose of this study was to report our experience with five cases of a. baumannii-related pneumonia infections, seen in a regional hospital, karaj, iran. five cases were identified as having a. baumannii- related pneu...

during a period of 5 months of 276 faecal specimens of inpatients, aged 0 to 5 years old, with diarrhea in zahedan, were screened for evidence of enteric campylobacteria for isolation, the stool was plated on a selective medium and incubated at 42oc in a microaerophilic atmosphere for 48-72 hours. on gram stain, the organisms were small, curved, comma shaped and gram negative rods. the followin...

conclusion it can be concluded that prophylactic antibiotics do not have any preventive effect on wound infection in a double blind setting. according to our findings, routine antibiotic prophylaxis as recommended for biliary surgery (open or laparoscopic cholecystectomy) is now questionable. results the study population included 61 males and 69 females with the mean age of 49.3±9.6 and 51.8±9....

introduction: antibiotics have the potential to adversely affect the microbial community. for anaerobic digestion, a sufficient methanogenic population needs to be preserved in the system. the main aim of this study was determination of inhibitory concentration of oxytetracycline on methanogenic bacteria. methods: a 120 ml jacketed bioreactor with a 90 ml working volume was inoculated granular ...

bacterial endocarditis is a serious disease that could occur after invasive dental procedures. despite a large number of papers written about the knowledge of prevention of bacterial endocarditis among health care workers in western countries, little is known about awareness of this subject among practitioners and students in other countries. the purpose of the present study was to assess the k...

background in recent decades, bacterial antibiotic resistance (especially in enterococci) has become a significant problem for human and veterinary medicine. one of the most important antibiotic resistances in enterococci, vancomycin resistance, is encoded by van gene family. objectives the aim of this study was to investigate antibiotic resistance to vancomycin in enterococci and the genes res...

background: extended spectrum beta lactamases (esbls) are an important cause of transferable multidrug resistance (mdr) in gram-negative bacteria. the most described esbl genes are generally found within integron-like structures as mobile genetic elements. the aim of this study was to identify the accompanying of class 1 integrons and esbls in the mdr e. coli isolates. methods: susceptibility t...
