background staphylococcus aureus is a common cause of infections among humans and animals and it is known as a community-acquired and nosocomial pathogen. most of the isolates contain lysogenic phages which are responsible for production of various virulence factors such as enterotoxins, staphylokinase, β-lysin, lipase, exfoliative toxin a and pantone-vlaentine leukociden (pvl). all staphylococ...

Several complications attributed with Herpes virus related infections and the emergence of drug resistant viruses prompt scientists to search for new drugs. Several terpenoids and coumarins have shown anti HSV effects while no sesquiterpene coumarin have been previously tested for HSV treatment. Three sesquiterpene coumarins [badrakemin acetate (1), kellerin (2) and samarcandin diasteromer (3) ...

INTRODUCTION Treatment-resistant trigeminal neuralgia is a distressing condition, for both the patient and the treating doctor. To our knowledge, there are no reported cases of trigeminal neuralgia successfully treated with oral sumatriptan in the literature. CASE PRESENTATION A 51-year-old Caucasian woman was prescribed opiate analgesia for management of her treatment-resistant trigeminal ne...

background: infertility affects about 10-15% of reproductive-age couples. about half the causes of infertility are female related and approximately 40% of the cases are caused by anovulation, mostly in pco women. objective: this study was conducted to determine and compare the effects of two drug treatment regimens: higher dose of clomiphene and a combination of lower dose of clomiphene and tam...

results disk diffusion agar showed that 96 strains (48%) were resistant to gentamicin, 89 (44.5%) to ciprofloxacin, 127 (63.5%) to erythromycin, 142 (71%) to tetracycline, 11 (5.5%) to teicoplanin, 32 (16%) to vancomycin, none to linezolid and 96 (48%) to co-trimoxazole. the mics of the resistant isolates were as follows; 88 strains had mic ≥ 32 μg/ml to vancomycin and 59 strains had mic ≥ 32 μ...

conclusions our results illustrated the presence of clonal groups of highly gentamicin-resistant strains of mrsa in hospitals in tehran. the php typing method provided useful information for both clonal dissemination and determining the epidemiological links of the clonal groups of the mrsa strains. materials and methods a total of 301 s. aureus isolates were collected during january to novembe...

results two- to four-fold decrease in minimum inhibitory concentration (mic) and two-fold increase in accumulation were observed for etbr in the presence of cccp for 67% (8) of 12 mdr strains. with cccp, two- to four-fold decrease in mic and 1.4- to 1.8-fold increase in the accumulation of β-lactames, tet, cip and mtz were obtained for 42% (5) of the mdr strains. six, five and three of the 12 m...

background hospital patients who are nasal carriers of methicillin-resistant staphylococcus aureus (mrsa) are a high-risk potential threat to themselves and other hospitalized patients. the high antibiotic resistance of these isolates renders the treatment of related infections difficult. objectives the present study, for the first time investigated the prevalence of mrsa isolates in nasal carr...

conclusions the β-lactamase disk test is appropriately sensitive to detect esbls in mdr isolates of e. coli. background most urinary tract infections (utis) are caused by escherichia coli (e. coli) species. due to infections outbreaks of e. coli strains with multiple mechanisms of resistance to β-lactam antibiotics, the sensitivity of confirmatory tests to detect the extended spectrum β-lactama...
