Acids, alkalies, salts, glucosides, and certain toxins diffuse more quickly into 0.9 per cent. salt solution than into agar-agar and gelatin suspensions. The inhibitory effect of the colloids grows with increase in concentration, which increase affects both the velocity and extent of the diffusion. In the case of gelatin the degree of diffusion is approximately in inverse proportion to the squa...
Algae are rich sources of amino acids, terpenoids, florentines, alkanes, halogenated ketones, steroidal compounds, fatty acids, and phenols that can be used in the pharmaceutical industry. The acetone and ethanol extracts, and the supernatant of the algae Chlorella vulgaris CCATM210-1, were used in this study. After culturing the Algae, and preparing the supernatant and extracts, the antibacter...
BACKGROUND AND PURPOSE A simplified antifungal disk diffusion test using Mueller-Hinton agar containing 2% glucose and methylene blue 5 microg/mL (GM-MH, Clinical and Laboratory Standards Institute [CLSI] M44-A) has proved to correlate well with the standard reference test. A new azole, voriconazole, has recently been approved for clinical therapy in Taiwan. This study investigated the reliabil...
discussion our results indicated that agar screening was superior to oxacillin disk agar diffusion. a comparison between the antibiotic sensitivity patterns of the mrcns and the methicillin-susceptible coagulase-negative staphylococci (mscns) showed that the mrcns were predominantly multiple-drug resistant isolates as the simultaneous resistance rate to 4 or more antibiotics in the mrcns and ms...
BACKGROUND Coagulase-negative staphylococci (CNS) are a common cause of nosocomial infections. In recent years, an increase in the incidence of methicillin-resistant coagulase-negative staphylococci (MRCNS) has led to the severity of the disease. OBJECTIVES The aim of this study was to isolate and identify MRCNS strains by oxacillin disk agar diffusion, oxacillin agar screening, and polymeras...
Orange peel extract solution contains mucilage flavor and three types of glycosides. Limonene is one of the terpenoides in some vegetables, fruits and food; that plays as an antioxidant in juice. As it has anti-microorganism effects on some bacteria, we carried out the antifungal effects of limonene versus orange extract. In the present study the effects of orange extract and two types of limon...
Background and Aim: Ferula gummosa Boiss. (Barije) is an Iranian indigenous plant that has medical and antifungal properties. The current study was done to determine the effect of aqueous an alcoholic extracts of Ferula gummosa Boiss root on in vitro growth of fungi. Materials and Methods: In this experimental study, the plant was dried in the dark and aqueous, alcoholic extracts of its root po...
Based on the requirement of a glutathione-deficient mutant strain of Saccharomyces cerevisiae to take up external glutathione for growth on synthetic media, a simple agar diffusion test for quantitative detection of total glutathione from various sources was established. Glutathione concentrations can be reliably detected in a less expensive way, requiring less technical effort compared to enzy...
A regression line for correlating zones of inhibition of a 75-mug mezlocillin disk with minimal inhibitory concentrations of mezlocillin for Enterobacteriaceae and nonfermenters was calculated. Correlation was excellent (r = -0.96) for all species tested except Pseudomonas cepacia.
