The MICs of the macrolide clarithromycin for 31 clinical isolates of Mycobacterium kansasii were determined by three different methods. The methods employed were the proportion resistance method on 7H10 agar, the radiometric (BACTEC) method, and the T100 method of datum analysis. All methods gave similar results. The MICs were in a narrow range from 0.16 to 0.50 microgram/ml, with the MICs for ...

BACKGROUND Combined effects of leaks, mechanical property of respiratory system and upper airway (UA) patency on patient-ventilator synchrony (PVA) and the level of clinically "tolerable" leaks are not well established in home ventilators. METHODS We comparatively assessed on a bench model, the highest leak level tolerated without inducing significant asynchrony ("critical leak") in three hom...

The impact of naturally occurring arbuscular mycorrhizal fungi on soybean growth and their interaction with Heterodera glycines were evaluated in nematode-infested and uninfested fields in Kansas. Ten soybean cultivars from Maturity Groups III-V with differential susceptibility to H. glycines were treated with the fungicide benomyl to suppress colonization by naturally occurring mycorrhizal fun...

Plants recognize invading pathogens and respond biochemically to prevent invasion or inhibit colonization in plant cells. Enhancing this response in crop plants could improve sustainable methods to manage plant diseases. To enhance disease resistance in soybean, the soybean phytoalexin glyceollin was assessed in soybean hairy roots of two soybean genotypes, Spencer and PI 567374, transformed wi...

Macrophomina phaseolina is a devastating soil-borne fungal plant pathogen that causes charcoal rot disease in many economically important crops worldwide. So far, no registered fungicide is available against this plant pathogen. This study was planned to examine the antifungal activity of an allelopathic grass Cenchrus pennisetiformis (Hochst. & Steud.) Wipff. for the management of M. phaseolin...

Enzymatic activity e.g., pectinase, cellulase, protease and lipase of different fungal pathogens causing stalk rot disease in corn was determined. In-vitro studies; corn stalk rot pathogens viz., Cephalosporium acremonium, Fusarium moniliforme, F. graminearum, F. semitectum, Macrophomina phaseolina, st. 1, M. phaseolina st. 2, Rhizoctonia solani st.1, R. solani st. 2 and Verticillium albo-atrum...

This study analysed the competition scheduling of future top 100 and 250 ranked tennis players from international tournament profiles at ages 13–18y. Retrospective data were for 165 (T100) (T250) males during their junior eligibility. Tournament/match volumes, days between tournaments consecutive (<8 between) quantified professional events. A two-way (age x ranking) analysis variance determined...
