bacteremia is an important infectious disease which may lead to death. common bacteria and pattern of antibiotic resistance in different communities are different and understanding these differences is important. in the present study, relative frequency and pattern of drug resistance have been examined in bacteria isolated from blood cultures in razi hospital laboratory. the method of the study...

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...

Background: The emergence and propagation of different phylogenetic groups of antimicrobial-resistant E. coli have become a worldwide health concern in human and veterinary medicine. Therefore, the evaluation of the phylogenetic distribution of antibiotic-resistant E. coli is important for therapeutic and economic purposes. The aims of this study were to determine phylogenetic groups and patter...

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...

E.coli is one of the serious pathogen that can cause tremendous therapeutic problem by developing resistance against antibiotics. The drug resistance in bacterial population is may be due to a genetic and non genetic mechanism (Choudhary 1988). Regarding genetic mechanism most drug resistant microbes emerged as a result of genetic changes and subsequent processes by antimicrobial drugs. The dru...

Postural disturbances are one of the first reported symptoms in patients with Multiple Sclerosis (MS). The purpose of this study was to investigate the effect of supervised resistance training on postural control in MS patients. Postural control was assessed using amount of sway variability [Root Mean Square (RMS)] and temporal structure of sway variability [Lyapunov Exponent (LyE)] from 15 MS ...

Background & Aims: Duo to clinical use of antibiotics, pseudomonas aeruginosa strains with multiple drugs resistance have significantly increased throughout the world. Betalactamase production is one of the Mechanisms involved in resistance to pseudomonas aeruginosa resulting in many problems in the treatment of infections caused by this bacterium. The aim of this study was molecular analysis o...
