conclusions due to the increasing resistance of pathogens to usual empirical antibiotics, it is reasonable to stress upon preventive measures, so that a minimum number of neonates develop sepsis. results coagulase-negative staphylococci (cons) were the most prevalent pathogens isolated from blood specimens in early and late-onset disease. escherichia coli and klebsiella were the most causative ...

conclusions this results of the study show that the most contamination in nicus is from gram-negative bacteria and ciprofloxacin is the most effective antibiotic for treatment. thus, the control of infections in nicus in hospitals is very important. results during the seven-month study on 105 samples, including 85 (81%) urine samples and 20 (19%) blood samples, 81 samples (77.1%) were gram-nega...

conclusions in conclusion, these results suggested a need for a switch to second line therapy regimens for treatment of infected patients in the iranian population. results helicobacter pylori infection was detected in 22 patients (22.92%). identity of the isolates was confirmed by pcr using glmm primers. chronic gastritis, duodenitis, intestinal metaplasia, dysplasia and cancer were detected a...

the aim of the study was to determine the resistance patterns of pseudomonas aeruginosa isolates recovered from patients with surgical wounds in hospitals and also to investigate their epidemiological relatedness using molecular typing techniques. twenty pseudomonas sp. isolated from surgical wounds were subjected to antibiotic susceptibility testing by disk diffusion, plasmid profile, sds-page...

background and aims. although wearing a white coat is an accepted part of medical and dental practice, it is a potential source of cross-infection. the objective of this study was to determine the level and type of microbial contamination present on the white coats of dental interns, graduate students and faculty in a dental clinic. materials and methods. questionnaire and cross-sectional surve...

introduction: p. aeruginosa is an important multi-drug resistant (mdr) opportunistic pathogen in hospital-acquired infections. several methods based on dna analysis have been used for investigating genetic diversity of p. aeruginosa isolates. among them, rep‑pcr typing has been introduced as a rapid, low cost method with high discriminatory power. the aims of this study were to investigate geno...

background shiga-toxigenic escherichia coli is an important human pathogen cause of diarrhea, hemorrhagic colitis, hemolytic uremic syndrome and thrombotic thrombocytopenic purpura in humans is a significant public health. objectives the aim of this study was to determine the molecular characteristics and antimicrobial resistance properties of shiga toxigenic escherichia coli (stec) strains wit...

conclusions due to the variable nature of antibiotic susceptibility patterns and etiological agents of septicemia, continual assessment of the most frequent pathogens associated with bloodstream infections and detection of their sensitivity patterns to locally available antibiotics seem to be reasonable measures. results from a total of 491 blood cultures, 74 (15.1%) samples were detected as po...

background neonatal sepsis is a serious problem in neonatal intensive care units, as it causes high rates of morbidity and mortality. objectives the purpose of this study is to evaluate various etiologic agents, antimicrobial susceptibility, clinical manifestations and the mortality rate in an intensive care unit in kashan, iran. patients and methods one hundred and four neonates with documente...
