results the results showed that the isolated e. coli strains were sensitive to these antibiotics: erythromycin (52.94%), tetracycline (76.47%), ceftazidime (41.17%), cefixime (35.29%), penicillin (76.47%), ampicillin (58.82%) and nalidixic acid (41.17%). examination of the herbal extracts showed that the highest maximum inhibitory concentration (mic) against drug resistant e. coli was 200 ppm. ...

using mutation specific pcr assay and analysis of position 108 amino acid in dihydrofolate reductase-thymidilate synthase gene in 70 plasmodium falciparum isolates of malarial patients from southern areas of iran, showed 4 different situations: iwild type (108-ser) ii-mutant type (108-thr) iii-mutant type (108-asn) and iv-mixed wild and mutant type (108-ser+thr) with frequency of 58(82.8%), 2(2...

background: nosocomial infections are an important cause of hospital mortalities. staphylococcus aureus (s. aureus) carriers among medical staff are an important source of nosocomial infections. the purpose of this study was to investigate the prevalence of the nasal carriers of s. aureus and antibiotic resistance in staff of nikuee hospital, qom, iran. materials and methods: in this cross-sect...

Formation of adamantane hydrocarbons and their confinement in SAPO-34 caused the long induction period and the quick catalyst deactivation in methanol conversion. Via ship-in-a-bottle synthesis, adamantane and methyladamantanes could be produced from methanol conversion in the cage of 8-ring SAPO catalysts under very mild reaction conditions.

drug resistance (especially multiple drug resistance) in mycobacterium tuberculosis makes global concerns in treatment and control of tuberculosis. rapid diagnosis of drug resistant strains of the bacteria has vital importance in the prognosis of the disease. the aim of this study was to identify the mutations responsible for drug resistance in mycobacterium tuberculosis strains derived from pa...

conclusions all the staphylococcus aureus strains and enterococcus faecium strains were sensitive to members of the oxazolidinone class of linezolid drug. development of multi drug resistance by gram positive bacteria constitutes a very serious challenge for medical practice. despite these rising rates, it is impossible to distinguish where they have originated from and special attention has th...
