Abstract
A description is provided for Mucor racemosus. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On soil, animal droppings, air, stored fruit and vegetables and associated with disorders of man and animals. DISEASE: Plants: Causes a spongy storage rot of various vegetables and fruit, e.g. sweet potatoes, potatoes and citrus, when kept at temperatures below 7°C (Chupp & Sherf, 1960). Man and animals: There are reports from bovine mycotic abortion (Austwick & Venn, 1962), avian pulmonary phycomycosis (RMVM 8, 596) and from skin in disease of guineapig (RMVM 7, 2000). However, doubt is cast on the role of M. racemosus as a pathogenic organism in warm blooded animals as it does not grow at 37°C. GEOGRAPHICAL DISTRIBUTION: World-wide. TRANSMISSION: By air-borne sporangiospores.
