Mucor pusillus . [Descriptions of Fungi and Bacteria

Abstract

Abstract A description is provided for Mucor pusillus [Rhizomucor pusillus] . Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On soil, air, mushroom compost, stored barley, fermenting cacao, bagasse, birds' nests and pathogenic to man and other warm-blooded animals (causing mycoses). DISEASE: Plants : causes storage rot and subsequent loss of stored grain which can be controlled by preventing heating of grain by adequate drying and ventilation and prevention of storage pests which often initiate heating and subsequent moulding. Man and animals : A commonly reported cause of phycomycosis in man and other warm blooded animals. It has been recorded from infections of many organs of the body including the alimentary tract, brain, heart, lungs, lymph nodes and nasopharynx of various hosts. The host range includes man (RMVM 2, 690; 9, 984, 469), cattle (RMVM 9, 473; 10, 1970), dog, harp seal (RMVM 3, 1664), horse (RMVM 3, 1249), pig, sheep (Borodenok, 1961) and wild fowl. It also causes mycotic abortion in cattle. It has been used in studies on experimental phycomycosis in mice (RMVM 3, 1566; 2, 1916), rabbits (RMVM 7, 4027; 2, 690), guineapig (RMVM 2, 690) and fowl (RMVM 7, 863). GEOGRAPHICAL DISTRIBUTION: Probably world-wide. TRANSMISSION: By air-borne spores.
