The influence of culture medium, incubation temperature, and antibiotic content on the reliability of methicillin disc-sensitivity tests on strains of Staphylococcus aureus was evaluated. Tests were performed with an inoculum giving semiconfluent growth of colonies on four media, with 5-mug and 10-mug methicillin discs at incubation temperatures of 30, 35, and 37 degrees C. With Sensitest agar ...

We screened forty crude extracts of twenty commonly used to treat bacterial infections for broad sp more affordable alternative against resistant organisms common pathogenic gram negative and gram positiv diffusion method followed by the tube dilution method extract, Escherichia coli showed sensitivity to zone of inhibition ranging from 7 – 19mm, fifteen Pseudomonas aeruginosa was sensitive to ...

Filter paper discs were impregnated with a solution containing 20 mg of triphenyltetrazolium chloride per millilitre, and used in the typing of catalase-positive Campylobacter species. Also used were filter paper discs impregnated with cephalothin at 30 micrograms/ml, 60 micrograms/ml and 3 mg/ml and nalidixic acid at the same concentrations, as well as commercially available discs containing 3...

The determination of collision-free shortest paths among growing discs has previously been studied for discs with fixed growing rates [1, 2, 3]. Here, we study a more general case of this problem, where: (1) the speeds at which the discs are growing are polynomial functions of degree β, and (2) the source and destination points are given as query points. We show how to preprocess the n growing ...

The development of Drosophila organ discs can be arrested by culturing them in adult male flies. These aged discs lose some of their differentiation competence and form incomplete imaginal structures. The more advanced the aging, the greater the loss of competence. Discs made to differentiate prematurely show deficiencies similar to aged discs. The age-induced defects can be repaired in a larva...

OBJECTIVE To study the expression of a disintegrin and metalloproteinase with thrombospondin motifs 5 (ADAMTS-5) in tissue samples of deformed human temporomandibular joint (TMJ) discs and cells obtained from the discs. MATERIALS AND METHODS Eleven adult human TMJ discs (nine diseased discs and two normal discs) were used in this study. The nine diseased discs were obtained from nine patients...

This study aimed to optimize the design and application of semi-constrained integrated artificial discs (SIADs) using a finite element (FE) analysis following implantation, wherein the zygapophysial joints of the segment were biomechanically reconstructed. An FE model of the L4-L5 segment was constructed. Variations in the stresses on the discs and zygapophysial joints were observed during 5° a...

The renewal of retinal rod and cone outer segments has been studied by radioautography in rhesus monkeys examined 2 and 4 days after injection of leucine-(3)H. The cell outer segment consists of a stack of photosensitive, membranous discs. In both rods and cones some of the newly formed (radioactive) protein became distributed throughout the outer segment. Furthermore, in rods (but not in cones...

Background: Mammaliicoccus sciuri is a multidrug resistant human pathogen. Literature on its role causing bovine mastitis scarce. Detection of M. from cow with clinical in Malkangiri district Odisha stimulated to ascertain status larger population and study characteristics genotypic phenotypic levels. Methods: 520 lactating cows various herds Odisha, India were screened for presence mastitis. M...

We present models in which the photoevaporation of discs around young stars by an external ultraviolet source (as computed by Adams et al 2004) is coupled with the internal viscous evolution of the discs. These models are applied to the case of the Orion Nebula Cluster, where the presence of a strong ultraviolet field from the central OB stars, together with a detailed census of circumstellar d...
