conclusions these findings showed no significant difference regarding the presence of icaadbc genes between blood and wound isolates. background the polysaccharide intercellular adhesion (pia) produced by staphylococcus aureus is effective in the protection of isolates from outer harsh conditions and progress of infection. objectives the aim of this study was to compare the icaabcd genes encodi...

introduction: multi-drug resistant (mdr) p. aeruginosa is constantly increasing and causing severe issues in combatting widely spread health problems. the aim of this study was to assess colistin susceptibility in mdr p. aeruginosa isolates obtained from different infection sites. methods: ninety clinical isolates of p. aeruginosa were collected from different hospitals of the tabriz university...

background: the aim of this study was to compare the biofilm formation and the prevalence of biofilm-associated genes between the isolates of methicillin-resistant (mrsa) and methicillin-susceptible (mssa) staphylococcus aureus. methods: in total, 209 s. aureus isolates were collected. the antibiotic susceptibility test was conducted using nine antibiotics according to the guidelines of clinica...

resistance of streptococcus pneumoniae against penicillin is considered to be of great importance. while low-resistant strains could be treated by penicillin, treatment of highly resistant strains is very difficult and needs broad-spectrum antibiotics. this study was performed in imam khomeini medical center, tehran, iran, from 1999 to 2001 to evaluate pneumococcal resistance against penicillin...

background and objectives: the pathogenic strains of escherichia coli cause severe septicemia, urinary tract infection and wound sepsis. resistance of this organism to the expanded-spectrum cephalosporins occurs via the production of extended-spectrum β-lactamases (esbls) such as tem and shv. these enzymes hydrolyze oxyimino cephalosporins (cefotaxime, ceftazidime) and monobactams (aztreonam). ...

metabolic alkalosis is characterized by high hco3- as it is seen in chronic respiratory acidosis, but ph differentiates the two disorders. there is no characteristic symptom or sign. orthostatic hypotension may be encountered. weakness and hyporeflexia occur if serum k+ is markerdly low. tetany and neuromuscular irritability occur rarely. we report the results of retrospective data analysis of ...

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...

abstract kawasaki disease is a systemic vasculitis that mainly affects younger children. although the definite cause still remains unknown but the clinical and epidemiologic findings discuss an infectious cause. the prevalence of incomplete kawasaki disease reported 15 to 36.2%, and it is more frequent in the extremes of the age spectrum. non delayed treatment of disease should be initiated bec...

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...
