“…32 A corymbifera has been identified as a cause of mesenteric lymphadenitis in cattle, 14,25 but we could not find any published reference to the presence of R pusillus in mesenteric lymph nodes of cattle or any other species. Previous reports, however, have described the recovery of R pusillus from bronchial and mediastinal lymph nodes 7,38 and brain 1,24 of cattle. This agent has also been associated with bovine mycotic abortion.…”

Zygomycotic Lymphadenitis in Slaughtered Feedlot Cattle

During the 12 months of 2006, zygomycotic lymphadenitis was diagnosed in 194 of 198 feedlot steers (0.04% of cattle slaughtered during that period) in a California slaughterhouse as part of bovine tuberculosis surveillance. Mesenteric lymph nodes were involved in 190 cases. Affected lymph nodes were enlarged (2 to 42 cm in greatest dimension), firm, and mottled gray-white to yellow with multiple granular or caseocalcareous foci. Histologically, nodal architecture was effaced by necrosis, granulomatous inflammation, and fibrosis. In approximately 20% of the cases, granulomas were mainly restricted to subcapsular sinuses and afferent lymphatic vessels, causing granulomatous lymphangitis. Nonseptate, irregularly branching hyphae with nonparallel walls and bulbous enlargements were common in necrotic areas and within the cytoplasm of multinucleated giant cells. Fungal cultures were performed on 124 affected lymph nodes using 7 media, but no zygomycetes were cultured. Fungal DNA was amplified from 20 lymph nodes. Amplicons from 16 nodes had nearly 100% homology with sequences for Rhizomucor pusillus; 4 amplicons had (> 98%) homology with Absidia corymbifera sequences. Zygomycosis should be considered in the differential diagnosis for granulomatous lymphadenitis in feedlot steers.

“…It has been found in soils from cultivated grassland and forest locations and also been cultured from volcanic mud (362). This organism has been isolated from hay (8), decaying grass and leaf mold, and a variety of food stuffs including barley, sorghum, wheat, corn (3), oat, rice, onions, cotton, groundnuts, sweet potatoes, pecans, brazil nuts, and tomatoes (125). Strains of this mold are responsible for the fermentation of various oriental foods and Indonesian alcoholic drinks (408).…”

“…This group is made up of closely related varieties of Rhizopus. They have been isolated from soil collected in forests and garbage (352) and from skin scrapings from otherwise healthy fowl (8). R. microsporus has also been isolated from moldy lumber in Norwegian sawmills (404) and other wood products (193,261,305,475).…”
