title: Geotrichum candidum as a possible cause of bovine abortion.
abstract: Geotrichum spp. are ubiquitous, saprotrophic fungi found in soil, organic matter, and silage, as a contaminant in food products and in the digestive tracts of mammals. The current study reports a case of Geotrichum candidum infection with dermatitis in an aborted bovine fetus with skin and lung lesions. A 6-month-old aborted male Holstein Friesian fetus displayed unusual lesions on the skin of the abdomen, thorax, and head, which was excessively thickened and wrinkled. These changes corresponded to orthokeratotic hyperkeratosis, neutrophil accumulation in the stratum corneum, a pyogranulomatous inflammatory infiltrate, and superficial dermal necrosis. Moderate suppurative multifocal pneumonia was observed. Large numbers of mononuclear cells and occasional fibrin thrombi within blood vessels were found in the lungs, brain, and cerebellum. Gridley staining revealed fungal structures within the skin lesions. The mycological exam demonstrated the growth of G. candidum, and phase contrast microscopy conducted on the abomasal fluid revealed hyphae compatible with this agent. The skin lesions observed, in association with the fungus isolated, indicated that the abortion was due to G. candidum infection of the bovine fetus.
