“…Consequently, the adult deer had been disposed by more conspicuous stress than young deer, which probably induced mucormycosis as well as Clostridium and Salmonella infections in the herd. Chihaya et al [5] investigated incidence of systemic mycosis in calves for 10 years and reported that 19 (4.7%) out of 406 autopsied had the infection and 12 of them were alimentary mycosis as seen in the present case. Infection of the Mucorales is characterized by the presence of suppurative or pyogenic cellular reaction and accumulation of neutrophils in the tissue [6], but not eosinophilic involvement.…”

ABSTRACT. Seven sika deer (Cervus nippon) died in a park where 30 deer were kept. One adult female deer died suddenly was necropsied. Severe hemorrhages were noted beneath the serous membranes of the forestomach and abomasum. Hyphal proliferation with neutrophil infiltration was observed in the mucous membranes of the stomaches, and the hyphae showed characteristics of order Mucorales. Catarrhal enteritis with hemorrhages was also observed. A large number of Clostridium perfringens was isolated from the contents of the abomasum and small intestine. The case was diagnosed as gastric mucormycosis associated with proliferation of Clostridium perfringens. The incidence occurred during breeding season and incorrect management was considered to be a predisposing factor for the infection. -KEY WORDS: Clostridium perfringens, mucormycosis, sika deer.J. Vet. Med. Sci. 60(8): 981-983, 1998 stained with hematoxylin and eosin (HE) and periodic acidSchiff (PAS) reaction. The mucous membranes of the forestomach and abomasum were hemorrhagic, hyperemic, necrotic and edematous associated with hyphal proliferation with neutrophil infiltration (Fig. 3). In these lesions the hyphae were nonseptate, aberrant and bulbous, and its width varied from 7 µm to 15 µm. The hyphae branched irregularly with vacant cytoplasm. The hyphae walls were thin and positive for PAS staining. Some hyphae branched frequently at right-angles. Remarkable thromboangiitis was observed in the mucous membrane, and marked proliferation of hyphae in the vascular wall and thrombi were noted. These hyphae showed characteristics of a member of order Mucorales [2,3,5]. Catarrhal enteritis associated with severe hemorrhages was observed in the small intestine (Fig. 4). The mucous epithelium of the large intestine was slightly necrotic and cellular infiltrations were found in the mucous membrane. Necrotic foci associated with hemorrhages scattered in the liver. From this deer, samples from the liver, heart, spleen, lungs, kidneys, cerebrum, and cerebellum were cultured on plates of blood agar, chocolate agar, heart infusion agar, desoxycholate hydrogen sulfide agar, sabouraud agar, and mannitol salt agar at 37°C for 48 hr, but no bacteria was isolated. The CW agar plate containing kanamycin and egg yolk was used for C. perfringens. In the contents from the abomasum, small intestine and large intestine, 8.0 × 10 8

“…A ocorrência de micoses nos pré-estômagos e abomaso dos ruminantes pode estar associada a quadros de acidose ruminal, por sobrecarga de carboidratos na dieta, utilização de antibióticos e outros fatores como prenhez, endometrites, mastites e septicemias (Chihaya et al 1988, Chihaya et al 1992. Casos de zigomicoses são pouco comuns em cães, gatos e suínos, afetando principalmente o trato gastrointestinal (Ginn et al 2007).…”

glaukommers@yahoo.com A retrospective study was performed to determine the main mycoses and oomycosis that affected domestic animals diagnosed in the Laboratório de Patologia Veterinária (LPV) of the Universidade Federal de Santa Maria (UFSM). A total of 29,686 exams (9,487 necropsy reports and 20,199 biopsy reports) performed between January 1990 and December 2012 were analyzed. Two hundred and thirty cases (78% of mycoses and 22% of pythiosis) were found. Data about epidemiology, clinical signs, gross and histologic lesions were obtained from the reports. In two cases the fungi observed were not identified. The main diseases observed, in descending order of prevalence, were: pythiosis, candidiasis, aspergillosis, zygomycosis, dermatophytosis, mallasseziosis, cryptococcosis, megabacteriosis, and sporothrichosis. Others diseases with only one cases each were histoplasmosis and pneumocystosis. Pythiosis affected mainly horses and the mycosis affected mainly companion animals (dogs and cats).INDEX TERMS: Mycoses, pythiosis, domestic animals, veterinary pathology.
