There are more than 60 species in the genus Phytophthora (94), and most are destructive plant pathogens. Extensive efforts are directed at the control of Phytophthora diseases each year, yet they still cause serious crop losses. For example, more than $200 million in lost production annually is attributed to Phytophthora diseases in Australia alone (47). Late blight, caused by P. infestans, pro...
The fungal community associated with the terrestrial photosynthetic orchid Gymnadenia conopsea was characterized through PCR-amplification directly from root extracted DNA and cloning of the PCR products. Six populations in two geographically distinct regions in Germany were investigated. New ITS-primers amplifying a wide taxonomic range including Basidiomycetes and Ascomycetes revealed a high ...
BACKGROUND We sought to determine the incidence of tinea pedis in patients with otherwise asymptomatic pedal interdigital macerations. Both diabetic and nondiabetic populations were compared. Age and body mass index were also examined for their significance. METHODS Fungal cultures of skin scrapings from 80 patients (77 male and 3 female; mean age, 65 years) with interdigital macerations were...
To elucidate the effect of fungal hyphae on the behaviour of Shiga toxin-producing Escherichia coli (STEC) O157, the spread and change in stress resistance of the bacterium were evaluated after coculture with 11 species of food-related fungi including fermentation starters. Spread distances of STEC O157 varied depending on the co-cultured fungal species, and the motile bacterial strain spread f...
Meeting the increasing food and energy demands of a growing population will require the development of ground-breaking strategies that promote sustainable plant production. Host-induced gene silencing has shown great potential for controlling pest and diseases in crop plants. However, while delivery of inhibitory noncoding double-stranded (ds)RNA by transgenic expression is a promising concept,...
Fungal infections represent a serious problem in neonatal intensive care units (NICUs) worldwide. Preterm infants are a vulnerable population for major events and adverse sequelae from fungal sepsis. The primary fungus of concern in neonates is C. albicans, whose colonization is associated with devastating complication and high rate of mortality. Among the risk factors responsible for developme...
The present study focuses on determining soil fungal community structure in different peanut-cropping sequences by using a high-resolution DNA fingerprinting technique: ribosomal intergenic spacer analysis (RISA). This study was initiated to determine fungal community profiles in four peanut-cropping sequences (continuous peanut, 4 years of continuous bahiagrass followed by peanut, peanut-corn-...
