The mould Penicillium frequentans Westling is, as its name implies, of very common occurrence on all kinds of material. According to Raper & Thom (1949), the Monoverticillate section of the genus Penicillium includes a P. frequentans series of three species, namely the type species, P. sprnulosum Thom and a less common species, P. purpurrescens (Sopp) n.comb. Webmer's classical studies of citri...

OBJECTIVE Hypersensitivity pneumonitis (HP) comprises a large group of diseases that occur secondary to inhalation of a variety of antigens. This report describes a little-known cause of HP, previously unreported in the English literature. METHODS Five patients (three women) with a mean age of 41 years who fulfilled the criteria for HP due to exposure to dry sausage dust were studied. The cli...

Conidia of Penicillium chrysogenum and Penicillium frequentans and sporangiospores of Rhizopus rhizopodiformis, Rhizomucor pusillus, and Mucor racemosus were subjected to partition in aqueous polymer two-phase systems. The partition behavior differed drastically between the conidia of the two Penicillium species and the sporangiospores of the three species of phycomycetes. This difference in pa...

Conidia of Aspergillus fumigatus, Aspergillus flavus, Aspergillus niger, Penicillium brevi-compactum, Penicillium frequentans, Penicillium spinulosum, and Penicillium verrucosum var. cyclopium were subjected to partition at varying pH values in an aqueous two-phase system containing charged polyethylene glycol. In the system, the partition behavior of the conidia of the Penicillium species vari...

Biological control of fungal plant pathogens can improve global food availability, one of the three pillars of food security, by reducing crop losses, particularly for low-income farmers. However, the interrelationships of many environmental variables can result in multiple interactions among the organisms and their environment, several of which might contribute to effective biological control....

A study was performed to determine the effect of arbuscular mycorrhizal (AM) fungal inoculation, using a locally isolated Claroideoglomus claroideum (Gc) ecotype, on the seedling development of chilean pepper plants, and to select an appropriate growth substrate. The first experiment consisted of two stages: (i) a seedling production stage of pepper plants were germinated and grown, inoculated ...
