Objective. The objective of the present study was to characterizer clinically of the healing process of cutaneous pythiosis in horses treated with triamcinolone acetonide. Materials and methods. We conducted a descriptive study, not probabilistic, of convenience. 24 horses were used with cutaneous pythiosis confirmed, a group of 12 animals was administered 50 mg of intramuscular injection of triamcinolone acetonide (TG) and the other group was not applied any treatment (CG). They are undergoing clinical and microscopic characterization of the lesion every 4 days until the complete recovery of granuloma in the GT. Being verified decreased fibrin bloody exudate, pruritus, presence of fistulae and output kunkers, likewise radiographic projections were performed to assess the degree of compromise bone and tissue fibrosis. Results. Macroscopically animals GT present progressive decrease in the clinical features of the disease at 16±1.4 days post treatment application. The wound contraction was 100% at 60±3.4 days after application of the treatment in all granulomas of GT, being highly significant (p<0.0001). Radiological monitoring of chronic skin lesions, met invasion to underlying tissues compromising bone structures, characterized by tissue fibrosis, moderate exostosis, bake as osteolysis and osteomyelitis. Neither of the animals in the CG showed improvement in clinical characteristics, and macroscopic of pythiosis and maintained equal to the first day throughout the study. Conclusions. The use of triamcinolone acetonide is a good therapeutic alternative for the treatment of granulomatous Pythiosis wounds in horses with 100% clinical recovery.Keywords: Pythium insidiosum, oomicosis, Kunkers, granuloma (Source: MeSh).

“…The main clinical alterations observed in all dogs were related to primary or secondary involvement of intestine, due to granulomatous inflammation unleashed by the agent (Salas et al 2009, Martins et al 2012, Galiza et al 2014, resulting in obstruction of the intestinal lumen. This is most commonly described clinical form of Pythiosis in dogs (Santurio et al 2006), though that may occur sporadically the cutaneous form of the disease (Howerth et al 1989, Torres Neto et al 2009, Pereira et al 2010.…”

RESUMO.-[Pitiose em cães na região semiárida do Nordeste, Brasil.] Descrevem-se os aspectos epidemiológicos, clínicos e patológicos de cinco casos de pitiose em cães na região semiárida do Nordeste. A doença ocorreu em cães com idade entre um e três anos, fêmeas e machos, de diferentes raças. Os cães eram criados em zona urbana, mas ocasionalmente eram levados para zona rural e tinham contato com áreas alagadas. Em um caso não havia informações no histórico sobre acesso à zona rural. Os principais sinais clínicos observados foram perda de peso, vômito, diarreia e tenesmo.Macroscopicamente havia espessamento da parede do intestino com massas firmes, irregulares, com áreas granulares amareladas entremeadas por tecido esbranquiçado, no duodeno, cólon e reto, que se estendia ao pâncreas e linfonodos, além de fígado e vagina. Na pele havia área de alopecia e ulcerações irregulares, algumas contendo pequenas cavitações com secreção serosanguinolenta. Microscopicamente havia inflamação piogranulomatosa e em um caso também havia necrose eosinofílica associada a imagens negativas tubuliformes pela hematoxilina e eosina, fortemente impregnadas pelo GMS e fracamente coradas pelo PAS. As hifas foram fortemente imunomarcadas pela imuno-histoquímica com anticorpo policlonal anti-Pythium insidiosum. A doença ocorre esporadicamente em cães no semiárido nordestino, entretanto deve ser incluída no diagnostico diferencial das doenças em cães com evolução crônica e proliferativa que acometem o sistema gastrintestinal, e frente a lesões cutâneas de difícil tratamento. We describe the epidemiological, clinical and pathological features of five cases of pythiosis in dogs in northeast semiarid. The disease occurred in dogs with age between one and three years, females and males of different breeds. The dogs were created in urban areas, but were occasionally taken to the countryside and then had contact with wetlands. The main clinical signs were weight loss, vomiting, diarrhea and tenesmus. Macroscopically there were intestinal wall thickening with irregular firm masses with yellowish granular areas interspersed with a whitish tissue, involving the duodenum, colon and rectum, extending to the lymph nodes and pancreas, and the vagina and liver. In the skin there were areas of alopecia and irregular ulcerations, some containing small cavitations with serosanguineous secretion. Microscopically there were pyogranulomatous inflammation and in one case also there were eosinophilic necrosis associated with negative images tubuliformes by hematoxylin and eosin, strongly stained by GMS and weakly by PAS. Hyphae were strongly marked by immunohistochemistry with polyclonal anti-Pythium insidiosum. The disease occurs sporadically in dogs in the semiarid Northeast, however should be included in the differential diagnosis of chronic diseases and proliferative aspect of the gastrointestinal system, and front skin lesions of difficult treatment.

“…Em humanos, dados epidemiológicos indicam que a dermatofitose está entre as zoonoses mais comuns do mundo, sendo considerada a terceira doença de pele mais comum em crianças menores de 12 anos e a segunda em adultos (Neves et al 2011). Por isso, a necessidade da realização de um diagnóstico preciso é relevante para o controle dessa micose nos animais domésticos e prevenção da contaminação em humanos (Galiza et al 2014).…”

ABSTRACT.-Torres M.E.L.M., Herculano P.N., Lima M.L.F., Soares P.T., Siqueira A.B.S., Souza-Motta C.M., Porto A. Dermatophytes are fungi that can cause superficial infections of the skin, hair and nails in man and animals. The most frequent dermatophyte species isolated from dogs and cats are Microsporum gypseum, most notably Microsporum canis. The crucial role during the infection process is the production of extracellular enzymes essential for the invasion and establishment of the pathogen in the host tissue. The objective of this research was to isolate dermatophytes from dogs and cats and evaluate the enzymatic profile of the isolates obtained. Hair samples and epidermal scales were collected from dogs and cats in veterinary facilities in Recife-PE, and the isolates were identified based on macroscopic and microscopic characteristics. The qualitative analysis of the enzymes urease, protease, lipase, collagenase and phospholipase was evaluated from the isolated dermatophytes. During 10 months, a total of 106 animals, comprising of 99 dogs and seven cats with clinical signs, regardless of sex and race were evaluated. Only eight animals were confirmed with dermatophytosis, mostly dogs (n=7), being six affected by M. canis and one by M. gypseum, the race most affected was Yorkshire (n=3). However, only one cat was confirmed with M. canis. No sex-related predisposition was observed regarding the occurrence of dermatophytosis in dogs and cats evaluated. Isolated dermatophytes showed similar profiles for the enzymes urease, lipase, protease, phospholipase and collagenase, important characteristic for pathogenic infections. The diagnosis of this zoonosis based on microbiological confirmation and a better understanding of the underlying mechanisms is of great importance for the treatment and prevention of fungal diseases in animals.
