Dissertação de Mestrado Integrado em Medicina Veterinária; Esta dissertação aborda a perspectiva clínica de algumas dermatites parasitárias frequentes no cão. O diagnóstico é algo difícil devido à semelhança da sintomatologia. Uma anamnese minuciosa é extremamente útil, nomeadamente no que se refere aos dados sobre a raça, a idade, o surgimento dos sintomas e sua evolução, e a presença de outros animais afectados. Existem animais portadores assintomáticos. Nas dermatites contagiosas é fulcral tratar os ambientes contaminados para eliminar fomites e prevenir recidivas. A sarcoptose, a queiletielose e as dermatofitoses são zoonoses. Um exame físico completo é relevante para o diagnóstico. As lesões e a sua distribuição fornecem pistas importantes da etiologia, auxiliando no estabelecimento de diagnósticos diferenciais. Algumas destas dermatites como a DAPP e as dermatites por Malassezia spp. têm uma forte componente alérgica. As dermatofitoses, as dermatites por Malassezia spp. e as demodicoses apresentam factores predisponentes que devem ser eliminados/controlados. Várias técnicas laboratoriais dermatológicas podem ser executadas na prática clínica. Os princípios activos usados no controlo/tratamento e respectivas apresentações comerciais têm acção contra vários agentes...

The aim of the present study was to evaluate the efficacy of the d-phenothrin/pyriproxyfen association against Psoroptes ovis, Cheyletiella parasitivorax, and Leporacarus gibbus infestations in naturally co-infested rabbits. Twenty crossbreed (New Zealand White x California) rabbits concurrently infested by the three mite species were randomly divided in two groups. All rabbits presented with hyperemia, erythema and formation of crusts in the ear canals caused by P. ovis. Infestations by both C. parasitivorax and L. gibbus were considered asymptomatic in all animals.Ten animals were treated with a 4.4% d-phenothrin and 0.148% pyriproxyfen spray formulation until have their body surface uniformly sprayed, including external ear canals. The other ten rabbits remained untreated, serving as control group. Observations were done on days +7, +14, +21, +28, and +35 post-treatment. The d-phenothrin/pyriproxyfen association showed 100% efficacy against the three mite species and was responsible for the remission of psoroptic mange lesions on treated animals. No signs of intoxication were observed. The results indicate that d-phenothrin/pyriproxyfen spray formulation in a single application is an effective and clinically safe option for the control of different mite infestations in rabbits.

The purpose of this study was to evaluate the efficacy of a topical formulation of selamectin in the treatment of cheyletiellosis in cats. Fifteen adult domestic cats from the same household with naturally occurring Cheyletiella sp. infestation were enrolled in the study. On each cat, 45 mg of selamectin was applied on days 0, 30, and 60. No other treatment or environmental decontamination was performed during the trial. On days 0, 30, 60, and 120, all cats were examined, epidermal debris was collected over the dorsal area of the body with flea combs for microscopic examination, and fecal flotations were done. Clinical signs had subsided by day 60 in all 15 cats and no signs of recurrence were apparent on follow-up 1 year later. All epidermal and fecal samples were negative by day 60. No adverse reactions were observed. Under the conditions of our study, topical selamectin was a practical and well-tolerated means of treatment for cheyletiellosis in cats.

The purpose of this study was to observe the efficacy of a topical pour-on formulation of ivermectin in the treatment of otoacariosis, cheyletiellosis, and toxocariosis in cats. Forty-five cats were treated. All cats received 2 to 4 topical applications of ivermectin on the skin between the shoulder blades in a narrow strip, 14 days apart. This practical treatment was effective in 96% (23/24) of cases of feline otoacariosis and in 100% (20/20) of cats with toxocariosis. All cats with cheyletiellosis (16/16) received 4 treatments and had resolution of clinical signs, but one Cheyletiella egg could still be found 45 days after the last treatment. The viability of this egg could not be evaluated, but the cats were still free of clinical signs on follow-up 6 months later. The treatment was well tolerated in all the animals. A few cats developed a transient small alopecic area and mild scaling at the site of application of the drug.

Twenty adult dogs (11 Cocker spaniels and 9 miniature Poodles) with naturally occurring cheyletiellosis were treated twice, at a three-week interval, with subcutaneous injections of ivermectin at the dose rate of 300 μg/kg. Ivermectin proved to be very effective against Cheyletiella yasguri infestation in dogs. All treated animals were completely cured after one or two treatments. No adverse reactions were noted. Ivermectin should be avoided in Collies and Collie crosses.

Cheyletiella blakei, an ectoparasitic mite of domestic cats, can cause an extremely annoying, persistent and pruritic dermatosis of obscure origin (cryptic infestation) in susceptible persons having close contact with infested cats. Although the prevalence of cheyletiellosis in humans and cats appears to be low, evidence of its occurrence in California is increasing. Cheyletiellosis is often underdiagnosed in both its natural host and in humans. The small size of the mite, lack of publicity about the disease, frequent absence of symptoms in infested cats and failure to recover the mite from humans contribute to its delayed recognition. When C blakei or other mites are suspected of being the cause of a dermatosis, medical entomologists may help to hasten the diagnosis by examining the patient's physical surroundings, potential vertebrate hosts and other sources for the presence of mites. After C blakei has been eliminated from cats with an appropriate pesticide, the disease in humans is self-limiting.
