“…Despite the predominance of males, this difference was significant only when +SG was compared with the group with other skin pathologies (-SG). The higher number of females in the (-SG) group is noteworthy because females could have been affected by dermatophytosis or parasite infections such as scabies, which are acquired independent of trauma [23]. As expected, a higher number of unneutered animals was observed in the infected population, signaling an increased risk of exposure to the etiological agent of sporotrichosis because of fights over territory and females [4, 9, 15].…”

BackgroundSporotrichosis is a neglected zoonosis caused by pathogenic fungi belonging to the Sporothrix schenckii complex. In Rio de Janeiro state, this disease reached an epidemic status with over 4700 domestic felines and around 4000 humans affected since the mid-90s. The present study evaluated clinical and epidemiological aspects and also the frequency of colonization and infection by these fungi in healthy cats and among those with suspicious cutaneous lesions, inhabiting four Rio de Janeiro state distinct areas.ResultsThree hundred and seventy-one cats were included in two groups: 175 healthy cats [CRG] and 196 cats showing lesions suggesting sporotrichosis [SSG]. Mycological diagnosis allowed SSG animals to be divided in positive [104 cats; +SG] and negative [92 cats; -SG] groups. Nails, oral mucosa and lesions swabs were submitted to culture and potential colonies were subculture for micromorphologycal analysis, dimorphism and molecular tests. In the CRG, only one cat was colonized in the oral cavity [0.57%]; in the -SG group, four animals showed colonization of the nail and/or oral cavity [4.3%]; while the highest frequency of colonization [39.4%] was observed in the +SG. All molecularly typed isolates were identified as S. brasiliensis.ConclusionThe results obtained here indicate that healthy cats have a minor role in sporotrichosis transmission within the state of Rio de Janeiro. Conversely, a higher participation of diseased feline in sporotrichosis transmission was evidenced, especially by the colonization of their oral cavity. Sporothrix brasiliensis equally affects and colonizes animals from distinct Rio de Janeiro state areas. Thus, we hypothesize that sporotrichosis is a uniform endemic throughout the state, whose transmission depends mainly on the contact with cats with sporotrichosis. Since Rio de Janeiro displays a world unique epidemic model of the disease, not fully understood, data on the infected and non-infected animals can be of major importance for future strategies of sporotrichosis prevention and control. Finally, considering the importance of the current concept of “one health”, the experience here observed can be helpful for distinct epizootias and/or zoonosis.

A higher prevalence of M. canis was observed by (NEVES et al, 2011), who evaluated the pathogens related to dermatophytosis in dogs and cats treated at the VH at the Universidade Federal de Mato Grosso, where 96.78% (270/279) of the dogs presented M. canis.…”

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. KEY-WORDS: Demodex spp.; dermatomycoses; Microsporium spp; Notoedres sp., scabies. RESUMO 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. PALAVRAS-CHAVE: Demodex spp.; Dermatomicose;, Microsporium spp.; Notoedressp.; sarnas.

“…Consciente desses dados conflitantes, além da ocorrência da lesão cutânea característica, exames de cultivo fúngico e histopatológico com resultados compatíveis foram necessários para firmar o diagnóstico de dermatofitose no intuito de descartar a possibilidade de diagnósticos equivocados, já que sabidamente outras doenças, tais como a foliculite estafilocócica, podem produzir lesões similares às descritas em casos de dermatofitose (Scott et al 1996). Esse alto percentual concorda com a prevalência de dermatofitose em cães e gatos (7,1%) obtida por Neves et al (2011) em seu estudo retrospectivo nesta mesma região e esse fato provavelmente se deve às influências climáticas, visto que Cuiabá-MT possui predominantemente clima quente e úmido, o que viabiliza a ocorrência da doença (Scott et al 1996). O baixo número de casos de doenças endócrinas neste trabalho pode estar relacionado ao número reduzido de cães senis atendidos, visto que cães mais velhos são mais susceptíveis ao desenvolvimento de algumas endocrinopatias, como hiperadrenocorticismo e hipotireoidismo (Halliwell 1990).…”

O objetivo deste trabalho foi avaliar as principais doenças de pele não neoplásicas em cães atendidos no Hospital Veterinário da Universidade Federal de Mato Grosso no ano de 2011. Nesse período, 112 casos dermatológicos foram atendidos, dos quais sistematicamente realizou-se biópsia de pele. Em 93,7% foi possível estabelecer o diagnóstico definitivo por meio de análise histopatológica junto a métodos diagnósticos complementares. As doenças cutâneas de maior prevalência eram de origem parasitária, imunológica, bacteriana e fúngica. Nesses grupos, as afecções cutâneas que mais ocorreram foram a demodicidose (20,9%), a leishmaniose visceral (12,4%), a atopia (10,5%), a dermatofitose (10,5%) e a piodermite superficial disseminada (8,6%). Essas cinco condições perfizeram juntas, pouco mais da metade de todas as doenças de pele de cães diagnosticadas neste estudo.
