As the result of a comparative study, it was found that a radiometric method utilizing an aerobic and an anaerobic vial was much more efficient than a tubed broth method in detecting bacteremia. The radiometric method detected 97 ( 92.4 percent) of 105 isolants as compared to 58 ( 55.2 percent) for the tubed broth method. Forty-seven (44.8 percent) of the isolants were detected only by the form...
Broomcorn seed (Sorghum vulgare) was used as raw material for bioethanol production. Optimum conditions were obtained from response surface method. Broomcorn seed flour (45 g/l) was treated by alkaline treatment and dual enzymatic hydrolysis (0.7 g/l of α- amylase and 0.42 g/l of amyloglucosidase). The hydrolyzed total sugar of 25.5 g/L was used in conventional bioethanol production (8.1 g/l) u...
The in vitro activity of fluconazole against 143 Candida spp. obtained from the bloodstreams of 143 hospitalized patients from 1995 to 1997 was studied. Susceptibility tests were carried out by two macrodilution methods, the M27-A and a modified M27-A method (0. 165 M, pH 7/morpholinepropanesulfonic acid-buffered RPMI 1640 medium supplemented with 20 g of D-dextrose per liter), and by the agar ...

سابقه و هدف: با توجه به ابتلای درصد بالایی از جمعیت به پوسیدگی دندان با ماهیت عفونی-میکروبی و اعمال هزینه های هنگفت درمانی بویژه در گروه های پرخطر مانند افراد دچار خشکی دهان، پیشگیری و کنترل آن بسیار حیاتی است. از طرفی به دلیل اقبال جامعه جهانی و کشورمان به درمان های سنتی و لزوم استخراج دارو از مواد طبیعی و گیاهان داروئی، مطالعه حاضر با هدف بررسی اثر آنتی باکتریال عصاره دو گیاه مریم گلی و پونه ...
OBJECTIVES Determination of bacterial antimicrobial susceptibility is usually performed using phenotypic methods. In this study, we developed a universal 16S rRNA and rpoB quantitative PCR assay for susceptibility testing of bacteria commonly isolated in clinical microbiology laboratories. METHODS Antibiotic susceptibilities for 24 bacterial strains of various species were tested by real-time...
OBJECTIVE To evaluate disinfectants for domestic use for the presence of bacteria, identify them, and determine their tolerance level to benzalkonium chloride. METHODS Fifty-two samples of commercially available disinfectants for domestic use were acquired at random in the metropolitan area of São Paulo, Brazil, and analyzed to detect the presence of bacterial contaminants. The isolated organ...
Sensitivity to commercial teat dips (nonoxinol-9 iodine complex and chlorhexidine digluconate) of 56 Staphylococcus (S.) aureus strains isolated from quarter milk samples of various German dairy herds treated with different teat dipping schemes was investigated in this study. The minimum inhibitory concentration was determined using a broth macrodilution method according to the German Veterinar...
In this study, in vitro antidermatophytic activity against Trichophyton mentagrophytes, Trichophyton rubrum, Microsporum canis, and Microsporum gypseum was studied by disk diffusion test and assessment of minimum inhibitory concentration (MIC) using CLSI broth macrodilution method (M38-A2). Moreover, antileishmanial and cytotoxicity activity of B. vulgaris and berberine against promastigotes of...
