ASPERGILLUS. Infections with aspergillus, a fungal organism, are seen in the ear canal where a common variety is aspergillus niger. Sinal infections are also caused by aspergillus and pulmonary infections by inhalation of the fungus. In the maxillary sinus there may be a ball of fungus called aspergilloma. If the infection invades blood vessels, any organ may become involved. Not all aspergillu...

Cavity-nesting alfalfa leafcutting bees, Megachile rotundata (F.) (Hymenoptera: Megachilidae), are excellent pollinators of alfalfa, Medicago savita L., for seed production. In commercial settings, artificial cavities are placed in field domiciles for nesting and, thereby, bee populations are sustained for future use. For this study, cells from leafcutting bee nests were collected in late summe...

BACKGROUND Aspergillus fumigatus is a saprophytic fungus which colonizes in the cavitary lesions in the lungs. In our part of the world, where tuberculosis is endemic, the healed tubercular cavities form a good nidus for this fungus. The fungus forms a fungal ball or aspergilloma within the cavity, which erodes the walls of the cavity and causes hemoptysis by erosion of the bronchial vessels. H...
