The steady-state CO(2) flux across thin layers of 30 g/100 ml albumin solutions was measured in two different CO(2) partial pressure ranges (boundary PCO(2) values 3 and 8 torr, and 160 and 650 torr, respectively). From the data the apparent diffusion coefficient for CO(2), DCO(2), was calculated. In the high PCO(2) range a value of DCO(2) was found which is to be expected on the basis of diffu...

Aim: To evaluate the anti-bacterial potential of pomegranate against Salmonella typhi. Methodology: Ethanolic extracts of pomegranate's different parts; peel, pericarp and fruit were screened for anti-bacterial activity against Multi-Drug Resistance (MDR) strain (UHS-14) by agar well diffusion method. 6% phenol was used as positive control. Results: The peel extract had the largest inhibitory z...

The MRSA-Screen test (Denka Seiken Co., Ltd., Tokyo, Japan), consisting of a slide latex agglutination kit that detects PBP 2a with a monoclonal antibody, was blindly compared to the oxacillin disk diffusion test, the oxacillin-salt agar screen, and PCR of the mecA gene for the detection of methicillin resistance in Staphylococcus aureus. A total of 120 methicillin-susceptible S. aureus (MSSA) ...

The activities of fluconazole and voriconazole against isolates of Candida spp. (n = 400) were tested by the E-test, disk diffusion, and the National Committee for Clinical Laboratory Standards (NCCLS) M27-A2 broth microdilution-based reference methods. More than 96% of isolates found to be susceptible to fluconazole by the reference method were identified as susceptible by the agar-based metho...

Male and female leaves and fruits of eleven different taxons of Iranian conifers (Cupressus sempervirens var. horizontalis, C. sempervirens var. sempervirens, C. sempervirens cv. Cereifeormis, Juniperus communis subsp. hemisphaerica, J. excelsa subsp. excelsa, J. excelsa subsp. polycarpos, J. foetidissima, J. oblonga, J. sabina, Platycladus orientalis and Taxus baccata) were collected from diff...

The ability of a fluconazole-containing agar screen assay to accurately detect isolates of Candida glabrata resistant to the azole antifungal agent fluconazole was evaluated on a collection of 100 clinical isolates of this organism. Results were correlated with the MIC of fluconazole for these isolates and compared with the results of a previously published disk diffusion-based fluconazole resi...

backgroundandobjectives:rapidandaccuratedetectionofmethicillinresistantstaphylococcus aureus (mrsa) is an important role of clinical microbiology laboratories to avoid treatment failure. the aim of this study was to compare conventional methods against the e-test minimum inhibitory concentration (mic) method to determine the best phenotypic method. materials and methods: methicillin resistance...
