“…Rhinosporidiosis affects both sexes (Londero et al 1977), and in relation to the age group, the disease presents great variation (Londero et al 1977, Nollet et al 2008, Trotte et al 2008, Burgess et al 2012, Santos et al 2014, Bernardo et al 2016, as identified in the present study. The disease predominantly affected Crioulo horses, and this may be related to the higher prevalence of this breed in the state of Rio Grande do Sul (Silva & Farias 2017).…”

“…In a study of equine diseases, the frequency was 0.3% (Marcolongo-Pereira et al 2014). In a study of tumor lesions of the nasal cavity of horses, rhinosporidiosis was the second major disease (Trotte et al 2008), representing 27.3% of the total lesions. The low rhinosporidiosis frequency may be related to the non-reporting of cases and because not all surgically excised nasal lesions are submitted to histopathological examination (França et al 1997).…”

Rhinosporidiosis is a disease caused by Rhinosporidium seeberi, an aquatic protist of the class Mesomycetozoa. It primarily affects the nasal mucosa and transmission is associated with contaminated water contact. This report describes seven cases of rhinosporidiosis in horses in Rio Grande do Sul covering the period of 13 years. The disease predominantly affected Crioulo and thoroughbred horses. No apparent gender predisposition occurs, and age ranged from two to 25 years, with a median of 10 years. The gross aspects were characterized by unilateral (85.7%, 6/7) or bilateral (14.3%, 1/7) polyps. These were soft to friable, whitish to pink, cauliflower-like, with an irregular, sometimes ulcerated surface, measuring 2.5 to 6.0cm in diameter. There was a severe inflammatory infiltrate of the submucosa was observed, associated with moderate proliferation of the epithelium, and numerous rounded structures were identified compatible with sporangia of R. seeberi. Rhinosporidiosis should be included in the differential diagnosis of other conditions affecting the respiratory tract of horses, and it is important to perform histopathology for diagnosis.

“…No Brasil, a rinosporidiose tem sido descrita em equinos, mulas e bovinos (Londero et al 1977, Trotte et al 2008, Portella et al 2010. Atualmente, Rhinosporidium seeberi não é mais considerado um fungo, mas um parasita mesomicetozoário, porém tem permanecido em revisões sobre a histopatologia das micoses (Guarner & Brandt 2011) e também permaneceu neste estudo, devido a sua morfologia e semelhanças com fungos como Coccidioides spp., por exemplo.…”

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.
