Cutaneous pythiosis in equines in the Amazon Biome / Pitiose cutânea em equídeos no Bioma Amazônico

The study aimed to describe the clinicopathological aspects of 37 cases of pythiosis, 34 in horses and three in mules, from properties located in the Amazon biome of Pará, Brazil. The clinical signs observed in the animals were weakness, poor-to-regular nutritional status, pale mucous membranes, itching at the lesion site, and lameness when the limbs were affected. The lesions were located on the lips, nostrils, rib region, thoracic and abdominal walls, scapular, distal limbs, foreskin, perineum and udder. Macroscopically, ulcerative and granulation-tissue-like masses were observed, with fistulous tracts filled with yellowish and foul-smelling serosanguinous discharges. In the biopsy, it was possible to visualize white and firm areas with foci of yellowish necrotic material and hardened masses, called kunkers. The histopathological examination showed a pyogranulomatous inflammatory reaction with the presence of Pythium insidiosum hyphae, which were impregnated with black, confirming the diagnosis of pythiosis in equids in the Amazon biome, being the first report of the disease in mules in the region.

O trabalho objetivou descrever os aspectos clínico-patológicos de 37 casos suspeitos de pitiose, 34 em equinos e três em muares, provenientes de propriedades localizadas no Pará, bioma amazônico brasileiro. Os sinais clínicos observados nos animais eram caracterizados por debilidade, estado nutricional de ruim a regular, mucosas pálidas, prurido no local da lesão, além de claudicação quando os membros foram acometidos. As lesões eram localizadas nos lábios, narinas, região das costelas, parede torácica e abdominal, escapular, distais dos membros, prepúcio, períneo e úbere. Macroscopicamente observavam-se extensas lesões ulceradas com intensa proliferação de tecido de granulação, de bordos irregulares, com tratos fistulosos, de consistência firme, denominados de "kunkers", preenchidos com material amarelado e friável, possuindo exsudação serossanguinolenta de odor fétido. Ao exame histopatológico observou-se reação inflamatória piogranulomatosa com presença de hifas de Pythium insidiosum, as quais se impregnaram de negro, confirmando o diagnóstico de pitiose em equídeos no Bioma Amazônico, sendo o primeiro relato da doença em muares na região.

Systemic phaeohyphomycosis in a dog caused by Cladophialophora bantiana

Background: Cladophialophora bantiana is a dematiaceous fungus that causes phaeohyphomycosis, a generic term used to describe a variety of unusual mycoses caused by fungi that have melanin in their cell wall. C. bantiana targets the central nervous system, commonly causing localized brain infections that may result in disseminated infections. In Brazil, minimal phaeohyphomycosis data are available, and information about C. bantiana infections in animals, especially canines, is scarce. Thus, the aim of this study was to describe the clinical and pathological aspects of systemic phaeohyphomycosis caused by C. bantiana in a dog. Case: A 1-year-old female Pit Bull presented with weight loss, reduced appetite, and a history of cutaneous lesions on the right thoracic limb; however, clinical evolution was not reported. The bitch had reportedly given birth recently. Physical examination revealed thinness, pale ocular and oral mucosa, submandibular lymph nodes, and enlarged popliteal lymph nodes. The bitch died after convulsive crises during hospitalization. At necropsy, white-yellowish multifocal nodules were observed in the liver and right kidney. The brain featured left cerebral hemisphere asymmetry with blood vessel congestion in the leptomeninges and an irregular brownish focal area on the surface of the right occipital cortex. Cross-sections of the formalin-fi xed brain exhibited compression of the left lateral ventricle and the presence of grayish and friable multifocal areas in the gray matter of the left parietal and right occipital cortices. Fragments of the lesions were collected for histopathological and microbiological examination. Histologically, the lesions were similar, characterized by hepatitis, nephritis, and granulomatous and necrotizing...

Cutaneous candidiasis caused by antifungal-resistant Candida sp. strain in canine individual / Candidíase cutânea causada por cepa de Candida sp. resistente a antifúngicos em indivíduo canino

The aim of the current report is to describe a cutaneous candidiasis case affecting a canine individual treated at the University Veterinary Hospital of State University of Maranhão (UEMA), in São Luís City. The patient had three-month history of skin diseases; it had been previously subjected to several treatments based on antibiotics, corticosteroids and antifungal drugs that have failed to show clinical improvements. Dermatological assessment has indicated generalized moist dermatitis, intense skin desquamation, alopecia, pruritus and meliceric crusts along the animal's body, mainly in its dorsal region. Complementary tests, such as skin cytology and microscopy, trichogram, qualitative PCR and serology for canine visceral leishmaniasis, as well as fungal culture and antifungigram were requested based on this scenario. Serology recorded inconclusive results for leishmaniasis, whereas PCR recorded negative results in the presence of the agent's DNA. Cytology, microscopy and trichogram results have evidenced fungal infection in the assessed samples. Moreover, mycological culture and antifungigram resulted in the growth of Candida sp. specimens capable of resisting antifungal agents such as amphotericin B, fluconazole, itraconazole and nystatin. The therapy adopted after candidiasis diagnosis confirmation comprised oral doses of manipulated ketoconazole, in combination to topical therapy with shampoo based on moisturizing formulas associated with Miconazole and Chlorhexidine (at 2%), for four weeks. After 30 days, when the adopted therapy was over, the aforementioned animal presented remission of the previously observed lesions and fully improved condition.

Esporotricose felina associada à dermatofitose secundária: relato de caso / Feline sporotrichosis associated with secondary dermatophytosis: case report

A esporotricose é uma doença fúngica subaguda ou crônica causada pelo complexo fúngico Sporothrix. Consiste em uma enfermidade zoonótica em que a infecção ocorre a partir da inoculação traumática do fungo em tecido cutâneo ou subcutâneo, sendo o felino doméstico o animal mais susceptível à doença. Os gatos desempenham um papel epidemiológico importante na transmissão e propagação da doença devido aos seus hábitos comportamentais e pela grande quantidade de microrganismos fúngicos que carregam em lesões cutâneas exsudativas, atuando assim como principal fonte de infecção e possuindo o maior potencial de transmissibilidade. É uma micose subnotificada e mais comumente diagnosticada no Rio de Janeiro, mas atualmente a enfermidade vem ganhando importância em diversas regiões do Brasil, onde tem sido observado um número crescente de casos em animais e seres humanos. Diante disto, o presente trabalho apresenta uma revisão bibliográfica sobre o tema, bem como o relato de um caso clínico de uma gata de 1 ano de idade com esporotricose e desenvolvimento secundário de outra zoonose importante para a saúde pública -a dermatofitose, com o intuito de alertar sobre a importância das infecções micóticas em felinos para a saúde única e evidenciando a importância do diagnóstico precoce e da colaboração e comprometimento do tutor para a terapêutica das enfermidades.

Sporotrichosis is a subacute or chronic fungal disease caused by the Sporothrix fungal complex. It consists of a zoonotic disease in which the infection occurs from the traumatic inoculation of the fungus in cutaneous or subcutaneous tissue, with the domestic feline being the animal most susceptible to the disease. Cats play an important epidemiological role in the transmission and spread of the disease due to their habits and the large amount of fungal microorganisms they carry in exudative skin lesions, thus acting as the main source of infection and having the greatest potential for transmissibility. It is an underreported mycosis and most commonly diagnosed in Rio de Janeiro, but the disease is currently gaining importance in several regions of Brazil, where an increasing number of cases in animals and humans have been observed. In view of this, the present work presents a bibliographic review on the subject, as well as the report of a clinical case of a one-year-old female cat with sporotrichosis and with the secondary development of another zoonosis important forpublic health - dermatophytosis, with in order to alert about the importance of mycoticinfections in felines for unique health and highlighting the importance of early diagnosis and the collaboration and commitment of the tutor for the treatment of diseases.

Dermatopatia isquêmica juvenil em um cão / Juvenile-onset ischemic dermatopathy in a dog

Background: Juvenile-onset ischemic dermatopathy is a rare dermatosis in dogs. Reports on this condition are scarce inthe literature, and its pathogenesis is poorly understood. This disease consists of a set of alterations that exhibit similarclinical and histological characteristics, and which are associated with cutaneous vasculopathic processes. Consequently,this case report describes the clinical case of a dog diagnosed with juvenile-onset ischemic dermatopathy.Case: A 9-month-old female mongrel dog exhibited significant tegumentary alterations, while other contact animals (siblingsand mother) did not. The patient history did not contain a complete record of vaccines, and included previous therapeuticfailures. A general skin examination revealed the presence of erythematous lesions containing crusts and erosions associated with extended areas with alopecia, especially in the ears, nose, and tail. Therefore, skin cytology and a parasitologicalexamination of the skin and cerumen were performed. These tests revealed the presence of neutrophilic inflammatoryprocess, bacterial inflammation, and various yeast-like structures compatible with Malassezia sp. The parasitological examination of the cerumen revealed the presence of numerous mites of the Otodectes cynotis species. Consequently, the dogreceived a treatment that included amoxicillin with potassium clavulanate, itraconazole, therapeutic baths with a shampoocontaining chlorhexidine and miconazole, and an antiparasitic medication containing sarolaner, which was administeredonce every 35 days. Thirty days later, the patient returned with a significant improvement of the lesions, except those inthe ears and tail; consequently, material from these two body areas was submitted to histopathological examination, andadditional tests were performed to allow differential diagnosis.

Fungal dermatitis by Scopulariopsis brevicaulisin Guinea pig (Cavia porcellus) / Dermatite fúngica por Scopulariopsis brevicaulis em Porquinho da Índia (Cavia porcellus)

Fungal dermatitis is classified into superficial, cutaneous and subcutaneous mycoses. However, the incidence of fungal dermatitis in small mammals is relatively low. Among rodents guinea pig the most affected specie, however it usually has an asymptomatic pattern. The present text reports an unusual case of fungal dermatitis in Caviaporcelluscaused by Scopulariopsis brevicaulis. The animal was received with complaint of alteration of coat around the neck, as well as report of incorrect feeding management. During the physical examination the presence of a dry and crusty dermatitis, negative on fluorescence test of wood. Samples of blood, skin, scabs and hair were collected for parasitic and mycological analysis. The hematological evaluation showed only a discrete eosinophilia; no ectoparasites were observed, but it was noticed the presence of Scopulariopsis brevicaulis. The animal underwent terbinafine and griseofulvin protocol, with total regression of the lesions after 30 days. S. brevicaulis is an unusual geophilic fungus causing animal mycosis, presenting more pathological reports in human mycoses, thus, representing a zoonotic potential. According to the clinical findings and results obtained from mycology assay, it was diagnosed dermatitis by Scopulariopsis brevicaulis, secondary to nutritional deficiency. The combined use of topical terbinafine with systemic griseofulvin was efficient in the treatment. Finally, it was recommended a dietary correction.

As dermatites fúngicas são classificadas em micoses superficiais, micoses cutâneas e micoses subcutâneas. No entanto, a ocorrência de dermatites fúngicas em pequenos mamíferos é incomum, sendo que entre os roedores o porquinho da Índia é a espécie mais acometida e a infecção costuma ser assintomática. O presente artigo relata um caso incomum de dermatite fúngica em Cavia porcellus causado pelo fungo Scopulariopsis brevicaulis. O animal foi atendido devido à queixa de alteração de pelagem ao redor do pescoço e erros no manejo alimentar. Durante o exame físico observou-se a presença de uma derma-tite crostosa de aparência seca, negativa no teste de fluorescência sob lâmpada de Wood para detectar dermatófitos. Foi cole-tado sangue e também amostras de pele, crostas e pelos para análise parasitária e cultivo micológico. Na avaliação hematoló-gica observou-se apenas uma eosinofilia discreta, no parasitológico não foram observados ectoparasitas. No cultivo micológico foi isolado Scopulariopsis brevicaulis. O animal foi tratado com terbinafina e griseofulvina havendo regressão total das lesões após 30 dias de terapia antifúngica. S. brevicaulis é um fungo geofílico incomum em casos de micose em animais, sendo mais relatado em micoses humanas e havendo um potencial zoonótico. Assim, baseado nos achados clínicos e exames laboratoriais concluiu-se que o caso se tratava de uma dermatite fúngica causada por Scopulariopsis brevicaulis secundária a deficiência nutri-cional, sendo que o uso combinado de terbinafina tópica com a griseofulvina sistêmica foi eficiente no tratamento em com-binação com a correção da dieta alimentar.

A esporotricose é uma micose subcutânea piogranulomatosa causada por um fungo saprófito que acomete grande variedade de animais e também os humanos. O diagnóstico baseia-se na anamnese, exame físico e exames complementares tais como citopatológico da secreção, histopatológico da pele acometida e no estudo morfológico macro e microscópico da cultura fúngica. O presente estudo tem como objetivo descrever os achados laboratoriais de um felino com esporotricose, associando-os com a forma clínica desta enfermidade. Um gato doméstico foi atendido no Hospital Veterinário Universitário Prof. Dr. Ivon Macêdo Tabosa no município de Patos, no estado da Paraíba, em julho de 2019. O paciente apresentava feridas na orelha com presença de secreção, aumento de volume com coloração avermelhada, áreas circulares de alopecia e descamação no membro pélvico esquerdo. Foi solicitado hemograma, bioquímica sérica, citologia e cultura micológica. Não houve alterações no eritrograma e plaquetograma. No leucograma, observou-se leucocitose com desvio a esquerda regenerativo. O exame citopatológico da lesão apresentou estruturas compatíveis com leveduras de Sporothrix spp. no fundo de lâmina e no interior dos leucócitos. No entanto, é sugerido que outros métodos diferenciais de diagnósticos sejam indicados para não excluir a possibilidade da doença.

Sporotrichosis is a subcutaneous pyogranulomatous mycosis caused by a fungus that affects a wide variety of animals and humans. Its diagnosis is based on anamnesis, physical examination, and complementary exams such as cytopathology of the secretion, histopathology of the injured skin and the macro and microscopic morphological study of fungal culture. This study aims to describe the laboratory findings of a feline with sporotrichosis, associating them with the clinical form of this disease. A domestic cat was treated at the University Veterinarian Hospital Prof. Dr. Ivon Macêdo Tabosa in the city of Patos, State of Paraíba, in july 2019. The patient had ear wounds with secretion, swelling with reddish color, circular areas of alopecia and flaking in the left pelvic limb. Blood count, serum biochemistry, cytology and mycological culture exams were requested. There were no changes in the erythrogram and platelet chart. In the leukogram, it was observed leukocytosis with a left regenerative deviation. The cytopathological examination of the lesion showed structures compatible with yeasts of Sporothrix spp. At the bottom of the slide and inside the leukocytes. However, it is suggested that other differential methods of diagnosis be indicated in order not to exclude the possibility of the disease.

Cutaneous mycobiota of boid snakes kept in captivity / Microbiota cutânea de serpentes Boidae mantidas em cativeiro

Boids are large, constrictor snakes that feed mostly on mammals, reptiles, and birds. These animals are commonly raised as pets, and their improper handling can favor the emergence of fungal infections, which can lead to dermatological diseases that are undiagnosed in nature. Here, we isolate and identify the filamentous fungi that compose the mycobiota of the scales of boid snakes kept in captivity at the Biological Museum of the Butantan Institute. Thirty individuals of four species were evaluated: four Eunectes murinus, twelve Boa constrictor constrictor, seven Corallus hortulanus, and seven Epicrates crassus. Microbiological samples were collected by rubbing small square carpets on the snake scales. We isolated five genera of fungi: Penicillium sp. (30%), Aspergillus sp. (25%), Mucor sp. (25%), Acremonium sp. (10%), and Scopulariopsis sp. (10%). Approximately half of the snakes evaluated had filamentous fungi on the scales, but only 12% of the individuals were colonized by more than one fungal genus. We found no dermatophytes in the evaluated species. Our results provide an overview of the fungal mycobiota of the population of boids kept in the Biological Museum, allowing the identification of possible pathogens.(AU)

Boidae são serpentes grandes e constritoras, que comem normalmente mamíferos, répteis e aves. São comumente criadas como animais de estimação, e seu manuseio inadequado pode favorecer infecções fúngicas emergentes, as quais podem causar doenças dermatológicas que não são diagnosticadas na natureza. Foram isolados e identificados os fungos filamentosos da microbiota das escamas das serpentes Boidae mantidas em cativeiro no Museu Biológico do Instituto Butantan. Trinta indivíduos de quatro espécies foram avaliados: quatro Eunectes murinus, 12 Boa constrictor constrictor, sete Corallus hortulanus e sete Epicrates crassus. As amostras microbiológicas foram coletadas por fricção, em pequenos quadrados de carpete das escamas das serpentes. Isolaram-se cinco gêneros de fungos: Penicillium sp. (30%), Aspergillus sp. (25%), Mucor sp. (25%), Acremonium sp. (10%) e Scopulariopsis sp. (10%). Aproximadamente metade das serpentes avaliadas tinham fungos filamentosos nas escamas e apenas 12% dos indivíduos foram colonizados por mais de um gênero. Não foram encontrados dermatófitos nas espécies avaliadas. Os resultados mostraram uma visão geral da microbiota fúngica da população de boídeos mantidos no Museu Biológico, o que permitiu a identificação de possíveis patógenos.(AU)

Canine sporotrichosis: report of 15 advanced cases / Esporotricose canina: descrição de 15 casos avançados

Sporotrichosis is a chronic, granulomatous and usually lymphocutaneous infection of animals and humans, caused by a dimorphic fungus, Sporothrix schenckii complex. The disease in dogs is considered rare, however, in the last years a crescent registration of cases was observed in Brazil, especially in the city of Rio de Janeiro. Fifteen dogs with ulcerated cutaneous lesions were seen at the Dermatology Service in the Small Animal's Hospital at Universidade Federal Rural do Rio de Janeiro, between January 2014 and October 2015. Most lesions were located on the head, mainly the nose. Lesions were even seen on the chest, disseminated on the body and on the limbs. Three dogs (20%) exhibited the cutaneous-lymphatic form, with lesions initially on the distal aspect of one leg and ascending via lymphatics up the leg to the trunk and head. It was not ruled out the disseminated form in at least 3 dogs (20%). They had consistent signs of generalized or disseminated disease exhibiting respiratory symptoms (nasal discharge, sneezing, stertorous breathing), anorexia and weight loss. Draining tracts and cellulitis were very common. Some had large areas of skin necrosis with exposure of muscle and bone. Definitive diagnosis was obtained by cytological examination of exudates, histological examination, and/or isolation of S. schenckii complex by fungal culture. Because of the severity of the lesions that mimic other disorders like neoplasms or autoimmune skin diseases, and due to the difficulties of getting an accurate diagnosis, this study describes 15 advanced cases of canine sporotrichosis.(AU)

A esporitricose é uma doença infecciosa crônica, granulomatosa e frequentemente linfocutânea, causada por um fungo dimórfico do Complexo Sporothrix schenckii. A doença em cães é considerada rara, no entanto, nos últimos anos, um número crescente de casos foi registrado no Brasil, especialmente no Rio de Janeiro. Quinze cães com lesões cutâneas ulceradas foram atendidos no Setor de Dermatologia do Hospital Veterinário de Pequenos Animais da Universidade Federal Rural do Rio de Janeiro, entre Janeiro de 2014 e Outubro de 2015. Todos os animais foram submetidos ao exame clínico e dermatológico. A maioria das lesões estava localizada na cabeça, principalmente no plano nasal. Havia também lesões no tórax, disseminada pelo corpo e nos membros. Três cães (20%) apresentaram a forma cutâneo-linfática, com lesões inicialmente nos membros e se propagavam via vasos linfáticos para o tronco e a cabeça. Não foi descartada a forma disseminada em pelo menos 3 cães (20%). Estes cães apresentaram sinais consistentes de doença generalizada ou disseminada, exibindo sinais respiratórios (descarga nasal, espirros, estertoração), anorexia e perda de peso. Fístulas e celulite eram muito comuns. Alguns tinham grandes áreas de necrose que desencadearam a exposição de músculo e osso. O diagnóstico definitivo da infecção foi obtido por exame citológico de exsudato e por exame histológico, e/ou apenas isolamento do complexo S. schenckii pela cultura de fungos. Por causa da severidade das lesões que imitam outras enfermidades, principalmente neoplasias e doenças autoimunes, e pela dificuldade de se obter o diagnóstico correto, este estudo descreve 15 casos avançados de esporotricose canina.(AU)

Fifteen dogs with ulcerated cutaneous lesions were seen at the Dermatology Service in the Small Animal's Hospital at Universidade Federal Rural do Rio de Janeiro, between January 2014 and October 2015. Most lesions were located on the head, mainly the nose. Lesions were even seen on the chest, disseminated on the body and on the limbs. Three dogs (20%) exhibited the cutaneous-lymphatic form, with lesions initially on the distal aspect of one leg and ascending via lymphatics up the leg to the trunk and head. It was not ruled out the disseminated form in at least 3 dogs (20%). They had consistent signs of generalized or disseminated disease exhibiting respiratory symptoms (nasal discharge, sneezing, stertorous breathing), anorexia and weight loss. Draining tracts and cellulitis were very common. Some had large areas of skin necrosis with exposure of muscle and bone. Definitive diagnosis was obtained by cytological examination of exudates, histological examination, and/or isolation of S. schenckii complex by fungal culture. Because of the severity of the lesions that mimic other disorders like neoplasms or autoimmune skin diseases, and due to the difficulties of getting an accurate diagnosis, this study describes 15 advanced cases of canine sporotrichosis.(AU)

A esporitricose é uma doença infecciosa crônica, granulomatosa e frequentemente linfocutânea, causada por um fungo dimórfico do Complexo Sporothrix schenckii. A doença em cães é considerada rara, no entanto, nos últimos anos, um número crescente de casos foi registrado no Brasil, especialmente no Rio de Janeiro. Quinze cães com lesões cutâneas ulceradas foram atendidos no Setor de Dermatologia do Hospital Veterinário de Pequenos Animais da Universidade Federal Rural do Rio de Janeiro, entre Janeiro de 2014 e Outubro de 2015. Todos os animais foram submetidos ao exame clínico e dermatológico. A maioria das lesões estava localizada na cabeça, principalmente no plano nasal. Havia também lesões no tórax, disseminada pelo corpo e nos membros. Três cães (20%) apresentaram a forma cutâneo-linfática, com lesões inicialmente nos membros e se propagavam via vasos linfáticos para o tronco e a cabeça. Não foi descartada a forma disseminada em pelo menos 3 cães (20%). Estes cães apresentaram sinais consistentes de doença generalizada ou disseminada, exibindo sinais respiratórios (descarga nasal, espirros, estertoração), anorexia e perda de peso. Fístulas e celulite eram muito comuns. Alguns tinham grandes áreas de necrose que desencadearam a exposição de músculo e osso. O diagnóstico definitivo da infecção foi obtido por exame citológico de exsudato e por exame histológico, e/ou apenas isolamento do complexo S. schenckii pela cultura de fungos. Por causa da severidade das lesões que imitam outras enfermidades, principalmente neoplasias e doenças autoimunes, e pela dificuldade de se obter o diagnóstico correto, este estudo descreve 15 casos avançados de esporotricose canina.(AU)

Diagnosis of fungal and parasitic dermatopathies in dogs and cats of Paraíba state, Brazil / Diagnóstico de dermatopatias fúngicas e parasitárias em cães e gatos na Paraíba, Brasil

This study aimed to diagnose fungal and parasitic dermatopathies, describing its casuistry in dogs and cats at the Veterinary Hospital (VH) of the Instituto Federal da Paraíba (IFPB), Sousa, Paraíba. The study was carried out at the Laboratory of Immunology and Infectious Diseases (LIID) and at the Small Animal Medical Clinic (SAMC), VH/IFPB, Sousa, Paraíba, Brazil. Fifty-eight animals with skin lesions, including 41 dogs and 17 cats, were evaluated. Samples from the lesions were processed, resulting in 12.2% (5/41) of dogs testing positive for dermatophytes; 60% (3/5) of those cases were confirmed with Microsporum canis infections. For scabies, 24.4% (10/ 41) of dogs tested positive; of these, 80% (8/10, p≤0.05) had Demodex canis infections. In cats, 17.6% (3/17) were positive for dermatophytes; of these, 67% (2/3) were confirmed to have Microsporum gypseum infections. The positive testing rate for scabies in cats was 17.6% (3/17); of these, 67% (2/3) were Notoedres cati infections. In one cat, a concomitant infection was found witha dermatophyte (M. gypseum) and scabies (N. cati). It was concluded that the occurrence of dermatopathies is high at the SAMC/VH/IFPB. The main dermatophytes found were M. canis in dogs and M. gypseum in cats, and the most frequent scabies were D. canis in dogs and N. cati in cats.

O objetivo desse trabalho foi diagnosticar as dermatopatias fúngicas e parasitárias, descrevendo a casuística dessas enfermidades em cães e gatos no Hospital Veterinário do Instituto Federal da Paraíba – IFPB, campus Sousa, Paraíba-PB.O experimento foi realizado no Laboratório de Imunologia e Doenças Infectocontagiosas – LIDIC e na Clínica Médica de Pequenos Animais - CMPA, HV/IFPB. Foram avaliados 58 animais, sendo 41 cães e 17 gatos. As amostras coletadas para as análises laboratoriais foram pelos e crostas das lesões. Obtiveram-se 12,2% (5/41) dos cães positivos para dermatófitos, destes, 60% (3/5) para Microsporum canis. Para sarnas, 24,4% (10/41) dos cães foram positivos, em 80% (8/10; p≤0,05) a infestação era por Demodex canis. Nos gatos, 17,6% (3/17) foram positivos para dermatófitos, destes, 67% (2/3) Microsporum gypseum. A positividade para sarnas em gatos foi 17,6% (3/17), destes, 67% (2/3) para Notoedres cati. Em apenas um felino foi encontrada infecção concomitante entre dermatófito (M. gypseum) e sarna (N.cati). Concluiu-se que é alta a casuística de dermatopatias na CMPA/HV/IFPB. O principal dermatófito encontrado em cães foi M. canis e em gatos M. gypseum. Dentre as sarnas Demodex spp. foi a mais frequente para cães e Notoedres sp. para gatos.

Padronização de multiplex PCR para detecção de dermatófitos em pelos e crostas de cães e gatos / Standardization of a PCR multiplex for the detection of dermatophytes in dogs and cats fur and crusts

Objetivou-se padronizar uma reação do tipo multiplex PCR (mPCR) para detectar Microsporum canis, Microsporum gypseum e o complexo Trichophyton mentagrophytes em amostras de pelos e/ou crostas de cães e gatos. 250 amostras de pelos e/ou crostas de cães e gatos foram analisadas por meio de exame direto e cultura, o DNA das mesmas foi extraído para mPCR. Primers foram desenhados e como controle positivo da reação utilizou-se o DNA extraído de colônias de M. canis (URM 6273), M. gypseum (URM 6921) e T. mentagrophytes (URM 6211), provenientes da Coleção de Culturas (Micoteca URM), Departamento de Micologia, Centro de Ciências Biológicas da Universidade Federal de Pernambuco (CCB/UFPE). Como controles negativos de reação, utilizou-se água destilada esterilizada e DNA extraído de Alternaria sp. para verificar a especificidade dos primers. Do total de amostras analisadas, 15 (6%) foram identificadas, em cultura, como dermatófitos, e destas, 10 foram M. canis, três M. gypseum e dois T. mentagrophytes (complexo). Destas 15 amostras positivas, 11 (73,3%) foram detectadas por meio da mPCR. Além destas, seis outras, negativas em cultura, foram identificadas como M. gypseum. Verificou-se uma boa concordância entre os resultados da cultura e mPCR (Kappa: 0,66). O protocolo padronizado neste estudo pode ser utilizado como um método de triagem, por apresentar uma sensibilidade maior que a da cultura, usado paralelamente aos exames de rotina, permitindo um diagnóstico em menor tempo.(AU)

The aim of this study was to standardize a multiplex PCR (mPCR) reaction to detect Microsporum canis, Microsporum gypseum and the Trichophyton mentagrophytes complex in dog and cat fur and/or crusts. 250 fur and/or crusts samples from dogs and cats were analyzed by direct examination and culture, DNA from them was extracted for mPCR. Primers were designed and the DNA extracted from colonies of M. canis (URM 6273), M. gypseum (URM 6921) and T. mentagrophytes (URM 6211) from the Collection of Cultures - URM Micoteca - Department of Mycology, Biological Sciences Center of the Federal University of Pernambuco (CCB / UFPE). As negative controls, sterile distilled water and DNA extracted from Alternaria sp., were used to verify the specificity of the primers. Of the total samples analyzed, 15 (6%) were identified in culture as dermatophytes, and of these, 10 were M. canis, three M. gypseum and two T. mentagrophytes (complex). Of these 15 positive samples, 11 (73.3%) were detected by mPCR. Besides these, six others, negative in culture, were identified as M. gypseum. There was good agreement between culture results and mPCR (Kappa: 0.66). The protocol standardized in this study can be used as a screening method, because it has a sensitivity greater than that of the culture, used in parallel to the routine exams, allowing a diagnosis in a shorter time.(AU)

Doenças micóticas em gatos no Rio Grande do Sul / Fungal diseases in cats in Rio Grande do Sul, Brazil

As enfermidades fúngicas são diagnósticos diferenciais de diversas morbidades de caráter infeccioso, degenerativo ou proliferativo neoplásico, principalmente em gatos, que é a espécie mais suscetível a estas. Este trabalho descreve os achados anatomopatológicos de doenças fúngicas em gatos no período de janeiro de 2005 a dezembro de 2015 pelo SPV-UFRGS. Foram revisados 1.274 protocolos de necropsia e encontrou-se 17 casos de micoses, correspondendo a 1,33% dos diagnósticos. Quanto às amostras provenientes de biopsias, foram verificados 2.615 protocolos e detectou-se 59 casos de doenças fúngicas, totalizando 2,25% dos diagnósticos, sendo revisados seus achados macroscópicos, microscópicos, colorações especiais e cultivo micológico. O principal diagnóstico encontrado foi esporotricose com 34 casos de biópsia e cinco de necropsia. Criptococose obteve seis diagnósticos na necropsia e 13 na biópsia. O pseudomicetoma dermatofítico possui cinco casos de biópsia e dois de necropsia. Histoplasmose obteve um diagnóstico na necropsia e dois na biópsia. Aspergilose teve dois casos diagnosticados na necropsia. Candidíase e feo-hifomicose obtiveram um caso cada. Em quatro ocasiões, não se pode identificar o agente envolvido na lesão e foram classificados conforme a alteração morfológica em: dermatite fúngica, enterite fúngica, rinite micótica e dermatite e osteomielite fúngica. Através deste trabalho, pode-se identificar que a esporotricose foi o diagnóstico de doença fúngica mais frequente em felinos, seguido da criptococose e pseudomicetoma dermatofítico.(AU)

Fungal disease is included in the differential diagnosis of a wide range of disorders in cats. At the Department of Veterinary Pathology of Federal University Federal of Rio Grande do Sul (SPV-UFRGS), evaluation of records data of cats from January 2005 to December 2015 were examined. A total of 1,274 necropsy have been reviewed from which 17 cases of fungal infection was revealed accounting for 1.33%, and a total of 2,615 biopsies have been reviewed from which 59 cases of fungal infection was revealed, accounting for 2.25%. We retrospectively analyzed the gross and microscopic findings and the yield of additional diagnostic approaches employed. Sporotrichosis was the most common diagnosis with 34 cases found in biopsy and five necropsies. Cryptococcosis obtained six diagnoses through necropsy and 13 through biopsy. Dermatophytic pseudomycetoma was found in five cases in biopsy and two necropsies. Histoplasmosis diagnosis was obtained in one necropsy and two biopsies. Aspergillosis had two cases diagnosed in necropsy. Candidiase and phaeo-hyphomycosis accounted for one case each. In four occasions, it was not possible to identify the agent involved and the diagnosis was made regarding the morphological changes: fungal dermatitis, fungal enteritis, mycotic rhinitis, and fungal dermatitis and osteomyelitis. In this study, sporotrichosis could be identified as the most frequent diagnosis of fungal disease in cats, followed by cryptococcosis and dermatophytic pseudomycetoma.(AU)
