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...

conclusions according to the results, six strains were resistant to six or seven antibiotics and all strains were at least resistant to two antibiotics. however, for each of these resistant bacteria one bacteriophage was isolated from environmental samples, which showed the effectiveness of bacteriophages to remove clinically resistant e. coli strains. effective phages in vitro showed effective...

background: human exposure to antibiotic resistant bacteria (arb) is a public health concern which could occur in a number of ways. wastewaters seem to play an important role in the dissemination of bacteria and antibiotic resistant genes (args) in our environment. the aim of this study was to evaluate the occurrence of three groups of arb and their resistance genes in hospital and municipal wa...

background: methicillin resistant staphylococcus aureus (mrsa) nasal carriers play role in development of nosocomial infections and may increase treatment costs and mortality rate. these isolates, in addition to beta lactamase, is resistant to other drugs. carrier frequency and spectrum awareness of drug sensitivity in these isolates will be useful in choosing more effective methods of control ...
