Previous studies established that excised leaf tissues of alfalfa can be inoculated with Sclerotinia trifoliorum to select for heritable resistance, but the original procedures were not practical for use in large-scale screening programs. In this study, simplified leaf inoculation procedures for more rapid screening for resistance, based on direct application of leaf tissues to colonies of the pathogen on agar media, were evaluated. Cotyledons, unifoliate leaves, and leaflets of trifoliolate leaves of plants 7 to 21 days old from three relatively susceptible cultivars and one resistant germ pl

Ethological isolation among three strains of D. melanogaster reared for more than 35 generations on different food (standard cornmeal-agar-yeast medium, banana, and tomato) was tested in a series of multiple choice tests. Long-term maintenance on different substrates did not contribute to sexual isolation among three 'nutritional strains', as degrees of ethological isolation (Malogolowkin-Cohen's isolation indices) were not statistically significant. Males and females reared on different nutritional resources were equally successful in matings, i.e., significant differences in the number of co

This study, conducted on Pythium isolated from Colorado greenhouse crops, began in Apr. 2004. Symptomatic tissues from bedding plants and perennials were placed on selective media (P10VP). Resulting isolations of Pythium were transferred to cornmeal agar amended with the recommended low and high label rates of mefanoxam.

<strong>Background: </strong>Biofilm formation is seen in many pathogens like bacteria, fungi etc. It is one of the virulence factors of Candida species, an important pathogen and commensal. Indiscriminate use of antifungal agents, especially azole group in cancer patients may contribute to emergence of resistance in Candida isolates. Biofilm producing property of Candida also contributes to non-response to antifungals. Hence, speciation and detection of biofilm is useful for clinical management of Candida infections in cancer patients. Aims of this prospective study was to detect biofilm

AbstractDuddingtonia flagrans is a nematode-trapping fungus that has shown promising results as a tool to combat parasitic nematode infections in livestock. The fungus interrupts the parasitic lifecycle by trapping and killing larval stages on pasture to prevent re-infection of animals. One barrier to the fungus’ commercial use is scaling up production of the fungus, and specifically of chlamydospores, which survive the digestive tract to grow in fecal pats on pasture, thus have potential as a feed through anthelmintic. The purpose of this study was to evaluate the effect of dehydration on spo
