in this study, invitro evaluation of some iranian plants against staphylococcus aureus isolation of urinary tract infection by microtiterplate method. all 12 strains of staphylococcus aureus isolated from urine culture of hospitalized patients during the years 2012- 2013. minimum inhibitory concentration (mic) of plant extract and essential oilagainst bacteria were determined using micro diluti...

OBJECTIVE Urea is commonly used as a keratolytic substance in the treatment of onychomycoses to improve the penetration of antifungal drugs in the lesion sites. The aim of the present study was to investigate the inhibitory action of urea on samples of dermatophytes in vitro. METHOD Minimum inhibitory concentration of urea was determined for 31 samples of dermatophytes cultured in Sabouraud-d...

OBJECTIVE To evaluate the additive action of ginger starch on the antifungal activity of honey against Candida albicans (C. albicans). METHODS C. albicans was used to determine the minimum inhibitory concentration (MIC) of four varieties of Algerian honey. Lower concentrations of honey than the MIC were incubated with a set of concentrations of starch and then added to media to determine the ...

BACTEC 460 has now been phased out, so the search for an alternative is imperative. We have determined the activity of standard anti-tuberculosis drugs against intramacrophage Mycobacterium tuberculosis, in vitro, by using BACTEC 460 and MGIT 960 methods. The minimum inhibitory concentrations of isoniazid, rifampicin, ethambutol and streptomycin against intracellular M. tuberculosis H37Rv were ...

Minimum inhibitory concentrations of ceftizoxime for seven clinical isolates of Bacteroides fragilis were found to be markedly affected by inoculum size; the very low minimum inhibitory concentration values (less than or equal to 0.25 microgram/ml) obtained in tests with most strains were not sustained when the inoculum was raised 100-fold. Benzylpenicillin and cephalothin were also affected by...

The minimum growth-inhibitory concentrations (MICs) of azole antifungals were compared to their minimum sterol 14alpha-demethylation-inhibitory concentrations (MDICs) for clinical fungal isolates. The ascomycetous Candida yeasts tested were clearly divided into two groups: group I, consisting of C. albicans, C. tropicalis, and C. lusitaniae, had MICs that were much higher than the MDICs, wherea...

the present study was carried out to determine the potential antibacterial effect of essential oil of origanumvulgare against antibiotic resistant e.coli. in this study, the essential oil of origanumvulgare obtained by hydrodistillation was analyzed by gas chromatography coupled to mass spectrometry (gc-ms) in order to determine their chemical composition. the minimum inhibitory concentrations ...

Serum concentrations of cephalothin or kanamycin, or both, were determined in 53 patients undergoing cardiopulmonary bypass. Conventional doses of these antibiotics did not provide serum levels above the accepted minimum inhibitory concentrations in children. Adults had adequate serum antibiotic concentrations only when the antimicrobials were administered within 4 h of beginning cardiopulmonar...

Twenty-four isolates of nutritionally variant streptococci, previously categorized as species included among the viridans streptococci, were tested for susceptibility to 12 antimicrobial agents. Minimum inhibitory concentrations for these isolates and for a control group of viridans streptococci with no apparent nutritional deficiencies were determined in two microdilution systems. Pyridoxal hy...

OBJECTIVES To compare the in vitro activities of vancomycin and linezolid against methicillin resistant Staphyloccus aureus in our set up to help in formulating a better empirical treatment and reduce the emergence of vancomycin resistant Staphylococcus aureus. METHODS The study was conducted over a period of 6 months (1st July 2009-31st Dec 2009). Fifty Methicillin resistant Staphylococcus a...
