We evaluated the use of a chromogenic selective medium (MRSA ID) as a useful tool for the detection of methicillin-resistant Staphylococcus aureus (MRSA) in cystic fibrosis (CF) patient samples. Fifty-four MRSA isolates were detected by MRSA ID, while only 24/54 (44%) (odds ratio [OR], 2.79; 95% confidence interval [CI], 1.63 to 4.76) were detected by conventional methods. A chromogenic selecti...

Cryptococcus neoformans was isolated from nine pathological specimens cultured for mycobacteria. Five of these were recovered only in liquid TBC medium in the absence of growth on conventional substrates.

This review is devoted to the discussion of hadron properties in the nuclear medium and its relation to the partial restoration of chiral symmetry. Special attention is given to disentangle inmedium effects due to conventional many-body interactions from those due to the change of the chiral condensate. In particular, we shall discuss medium effects on the Goldstone bosons (pion, kaon and eta),...

These media appear to be distinctly different with respect to their physical and chemical properties. Yet the Separation between them becomes more blurred as information recorded in one medium can be copied readily onto another. Conventional examples are the miaofilming of newspapers, or the photocopying of whole fragile books. Modem scanning techniques allow any form of information whether pic...

improving cleaning and disinfection performance must be taken into account for prevention and control of infection. health care settings are engaged in a battle against healthcare associated infection (hais). the importance of infection prevention and control is increasing due to rapidly developing strains of multi-drug resistant organisms (mdros) that can result in serious illness and even dea...

Total internal reflection occurs for large angles of incidence, when light is incident from a high-refractive-index medium onto a low-index medium. We consider the situation where the low-index medium is active. By invoking causality in its most fundamental form, we argue that evanescent gain may or may not appear, depending on the analytic and global properties of the permittivity function. Fo...

Incorporating neomycin and nalidixic acid into a blood-agar base resulted in a medium highly selective for beta-hemolytic streptococci under conditions in which detection of streptococcal colonies by conventional means would have been very difficult.

abstract- a real-time, site-specific, machine-vision based, inter-row patch herbicide application system was developed and evaluated. the image resolution was 640 × 480 pixels covering a total area of 350 mm x 240 mm of a field composed of four quadrants of 350 mm x 60 mm each. the image frames were processed by labview® and matlab®. the developed algorithm, based on weed coverage ratio and seg...

We compared StrepB Select medium (Select) after enrichment with conventional culture for the detection of Group B Streptococcus (GBS). Postenrichment sensitivities of Select and conventional culture were 98.8% and 92.2%, respectively (P<0.05). Select was superior for detection of GBS from vaginal-rectal specimens. Growth of non-GBS colonies required additional work to exclude the presence of GB...

After having presented web-based Calculus courses for a number of years, we investigate the impact that this medium of instruction has on the student’s mathematical and general academic progress. Since our web-based model is much more flexible than the conventional contact lecture model, we surmised that this may contribute to the student becoming more of an independent learner than does the co...
