conclusions although previous studies have shown that a-g transition mutations in 23 srrna gene (domain v) are the main reason for the occurrence of high level macrolides resistance in b. pertussis, however, the mentioned single nucleotide polymorphisms (snps) have not been detected in our resistant strain. this is the first report of high level macrolide resistant b. pertussis, without snps in...
in this study, we investigated the antifungal effects of silver nanoparticles (ag-nps) on candida albicans (atcc 5027), saccharomyces cerevisiae (atcc 5027). investigating method by using minimum inhibitory concentration (mic) technique, some of drugs including amphotericin b, fluconazole and synthesized ag-nps have been obtained on the fungi and the changes on membrane reactions of yeasts have...
dermatophyte fungi are the etiologic agents of skin infections commonly referred to as ringworm. these infections are not dangerous but as a chronic cutaneous infections they may be difficult to treat and can also cause physical discomfort for patients. they are considered important as a public health problem as well. no information is available regarding the efficacy of antifungal agents again...
this study was carried out to evaluate the antimicrobial and antioxidant effectiveness of methanolic extract and different fractions (n-butanol, ethyl acetate, chloroform and n-hexane) of c.intybus seeds. the antimicrobial activity was determined by the disc diffusion method and minimum inhibitory concentration (mic) against a panel of microorganisms (four bacterial strains, i.e. p. multocida, ...
objective: teucrium polium l. (family lamiaceae) is a wild-growing flowering plant, found abundantly in south-western asia, europe and north africa. traditionally, t. polium has been used for different pathological conditions such as gastrointestinal disorders, inflammations, diabetes and rheumatism. the purpose of this study was to evaluate the antimicrobial effect of ethanol extract of teucri...
زمینه و هدف: کاندیداها شامل گونه های متنوعی از مخمرها و مخمر مانندها هستند که برخی از آنها و از جمله کاندیدا آلبیکنس فلور طبیعی بدن انسان را تشکیل می دهند و به صورت فرصت طلب در انسان بیماری ایجاد می نمایند، ولی داروهایی که بر ضد آنها در بازار وجود دارد و به کار می رود از نظر تعداد محدود هستند، که این خود می تواند باعث ایجاد مقاومت در آنها گردد. هدف این بررسی ارزیابی اثرات ضدقارچی داروهای نیستات...
background and objectives: presence of methicillin and multidrug resistance has associated coagulase negative staphylococci (cns) with high morbidity and mortality worldwide. the present study was carried out to study the susceptibility pattern of cns to various antimicrobial agents and to determine the prevalence of cns methicillin resistance in our hospital setting. materials and methods: a t...
conclusions regarding clinical and laboratory standards institute (clsi) definition for vancomycin susceptibility (mic < 2 μg/ml), it seems that vancomycin may not be considered as the best antibiotic in order to treat heteroresistant vancomycin intermediate s. aureus (hvisa) and vancomycin sensitive s. aureus (vssa) infections, and a new breakpoint for vancomycin and alternative antibiotics sh...
background and aim: in recent years, due to the indiscriminate and irrational use of synthetic drugs, the resistance of pathogenic microorganisms has increased; therefore, new compounds are vitally needed. the purpose of this study was to investigate the effect of ethanolic and aqueous extracts of berberis vulgaris on escherichia coli, klebsiella pneumoniae, proteus mirabilis, citrobacter frund...
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...
