Sea cucumber is presented as potential marine source of antimicrobial compounds. The purpose of this study is to evaluate antifungal effects of sea cucumber, Holothuria leucospilota, extracts on Aspergillus niger and Candida albicans. Methanol and chloroform extracts of the body wall, gonad and intestine of sea cucumber, H. leucospilota, collected from Persian Gulf, were evaluated for their ant...

The minimal inhibitory concentrations of 45 antimicrobial agents were determined for 14 strains of Bacterium actinomycetem comitans (Actinobacillus actinomycetem-comitans). All the strains showed good susceptibility to tetracyclines and chloramphenicol, but not to lincomycins. Some strains were clearly resistant to penicillins, cephalosporins, and nitroimidazoles. The lowest minimum inhibitory ...

objective: dental caries is a common infectious disease. streptococcus mutans is the prevalent decay microorganism. the anti streptococcus mutans activity of non fermented and semi-fermented tea has been shown. the aim of this study was to determine the anti streptococcus mutans activity of iranian green and black tea (non fermented and fermented type). materials and methods: the study was expe...

Minimum inhibitory concentrations, minimum bactericidal concentrations, and killing curve assays were measured after Legionella pneumophila was grown in human lung fibroblasts. Results of susceptibility testing of organisms grown intracellularly are compared with results for organisms grown by standard tube dilution methods.

Thirty six clinical isolates of Cryptococcus neoformans were tested for their susceptibility to 5-fluorocytosine and amphotericin B by the determination of minimum inhibitory concentrations and minimum fungicidal concentrations. 22.2% of the isolates were resistant to 5-fluorocytosine and 36.1% indicated 5-fluorocytosine tolerance. All strains were sensitive to amphotericin B.

background and purpose: candidiasis is a major fungal infection, and candida albicans is the major cause of infections in humans. the clinical and laboratory standards institute (clsi) developed new breakpoints for antifungal agents against c. albicans. in this multi-center study, we aimed to determine the drug susceptibility profile of c. albicans, isolated from iranian population according to...

conclusions the results showed that enterococci are common contaminants in food. indeed, this study indicates a high prevalence of multidrug-resistant enterococci in food of animal origin in iran. isolating some persisting enterococcal isolates revealed that continuous surveillance of antimicrobial resistance in enterococci from food is essential. materials and methods thirty samples of meat, c...
