      Random samples from asymptomatic leaves and branches of five native medicinal plants: Stachys lavandulifolia, Rumex pulcher, Hypericum scabrum, Starja bachteriarica and Achillea kellalensis were collected from Chaharmahal province of Iran and examined for the presence of endophytic bacteria and fungi with biological activity. From 8 isolated endophytic ...

Seven varieties of wheat seeds, such as BARI Gom-25, Gom-26, Gom-27, Gom-28, Gom-29, Gom-30 and Kanchan were studied to determine the prevalence seedborne fungi their effects on germinating seeds seedlings. The categorized into apparently healthy black point shriveled undersized seeds. Variation in different parameters (viz.Grading, weight, purity percentage, germination seedling growth) became...

Most Alternaria spp. are considered asexual but recent molecular evolution analyses of Alternaria mating-type genes show that the mating locus is under strong purifying selection, indicating a possible role in sexual reproduction. The objective of this study was to determine the mode of reproduction of an Alternaria alternata sensu lato population causing citrus brown spot in central Florida. M...

BACKGROUND Sensitivity to mold has been associated with asthma incidence, persistence, and severity. OBJECTIVE To examine the relationship between skin test reactivity (STR) to molds and specifically to Alternaria and asthma severity in a group of ethnically diverse children in Connecticut. METHODS Demographics and STR to 14 local allergens, including Alternaria, Penicillium, and mold mix, ...

Late reactions consisting of fever, malaise, and swelling at the site, 4 to 6 hr after injections of Alternaria extract occurred in several patients receiving immunotherapy with Alternaria. These patients had in common serum IgG precipitins and exquisite leukocyte histamine release sensitivity to Alternaria. Such precipitins were 3 times more frequent in patients receiving Alternaria immunother...
