Survey of Cryptococcus neoformansin pigeon (Columba livia) excreta in Public Square in Umuarama, ParanÃ¡, Brazil
Cryptococcosis is a common opportunistic fungal infection caused by encapsulated yeast of the Cryptococcus genus, mainly by the Cryptococcus neoformans and Cryptococcus gattii species. The fungus is acquired through the inhalation of environmental propagules or, more rarely, through organ transplants in immune-compromised individuals. Domestic pigeons (Columba livia) are related to the infection, mainly as natural...
Induction of defense mechanisms from filtrates of saprophytic fungi against early blight disease in tomato
The induction of defense enzymes presents efficient plant disease management when triggered by metabolic products of microorganisms. The aim of the present study is to select filtered saprobes fungi used for the management of early blight of tomato by inducing pathogenesis related to tomato plant. Filtrates of the fungi Curvularia eragrostidis, Curvularia inaequalis, Memnoniella echinata and Pseudobotrytis terrestris...
Eugenol and linalool: Comparison of their antibacterial and antifungal activities
Antimicrobial resistance is one of the greatest threats to human health. Alternatives to antimicrobials are needed to combat the rise of bacterial resistance. Essential oils (EOs) and their components are potential sources of new antimicrobials. The present study was conducted to evaluate the antibacterial and antifungal activities of two components of EOs. The antimicrobial mechanisms of eugenol and linalool were...
