Nymphal and adult ticks from three different tick species, Dermacentor variabilis Say, Ixodes scapularis Say, and Rhipicephalus sanguineus Latrielle, were treated with conidia and blastospores of the entomopathogenic fungi Beauveria bassiana (Bals.) Vuill. and Metarhizium anisopliae Metschnikoff. Dose-response experiments indicated that a critical(More)
BACKGROUND Inflammatory bowel disease (IBD) is hypothesized to result from stimulation of immune responses against resident intestinal bacteria within a genetically susceptible host. Mast cells may play a critical role in IBD pathogenesis, since they are typically located just beneath the intestinal mucosal barrier and can be activated by bacterial(More)
BACKGROUND Entomopathogenic fungi such as Beauveria bassiana are considered promising biological control agents for a variety of arthropod pests. Beauveria species, however, have the potential to elicit allergenic reactions in humans, although no specific allergens have been characterized to date. METHODS Four putative allergens were identified within B.(More)
Background: Beauveria bassiana is an important entomopathogenic fungus currently under development as a bio-control agent for a variety of insect pests. Although reported to be non-toxic to vertebrates, the potential allergenicity of Beauveria species has not been widely studied. Methods: IgE-reactivity studies were performed using sera from patients(More)
