Gliotoxin production in Aspergillus fumigatus contributes to host-specific differences in virulence.
BACKGROUND Gliotoxin is a epipolythiodioxopiperazine toxin that is made by the filamentous fungus Aspergillus fumigatus. Gliotoxin has a wide range of effects on metazoan cells in culture, including induction of apoptosis through inhibition of Nf-kappaB, and inhibition of superoxide production by phagocytes. These activities have led to the proposal that gliotoxin contributes to pathogenesis du...
متن کاملEcological and Genetic Differences between Cacopsylla melanoneura (Hemiptera, Psyllidae) Populations Reveal Species Host Plant Preference
The psyllid Cacopsylla melanoneura is considered one of the vectors of 'Candidatus Phytoplasma mali', the causal agent of apple proliferation disease. In Northern Italy, overwintered C. melanoneura adults reach apple and hawthorn around the end of January. Nymph development takes place between March and the end of April. The new generation adults migrate onto conifers around mid-June and come b...
متن کاملMixed infections and the evolution of virulence: effects of resource competition, parasite plasticity, and impaired host immunity.
Mixed-genotype parasite infections are common in nature. Theoretical studies analyze the effects of such infections over evolutionary time and predict an increase in virulence due to the competitive advantage of virulent parasites. In contrast, experimental studies compare the overall virulence of mixed and single infections within one generation. Although these within-generation comparisons ha...

متن کاملComparative genomics of host-specific virulence in Pseudomonas syringae.
While much study has gone into characterizing virulence factors that play a general role in disease, less work has been directed at identifying pathogen factors that act in a host-specific manner. Understanding these factors will help reveal the variety of mechanisms used by pathogens to suppress or avoid host defenses. We identified candidate Pseudomonas syringae host-specific virulence genes ...
