Resumo
Esta dissertação foi realizada no âmbito da conclusão do Mestrado Integrado em Medicina Veterinária da Universidade Lusófona de Humanidades e Tecnologias e teve como
objetivo o desenvolvimento do tema foliculite bacteriana superficial (FBS) canina. Inclui uma revisão bibliográfica sobre o tema e apresentação e discussão de cinco casos clínicos recolhidos no Hospital Veterinário Arco do Cego.
A foliculite bacteriana superficial é uma infeção do folículo piloso causada pelo
organismo Staphylococcus pseudintermedius, sendo uma das principais causas para prescrição
antibiótica em clínica de pequenos animais. A FBS normalmente ocorre de forma secundária a uma doença primária, sendo a mais comum de origem alérgica, como a dermatite atópica canina.
Os casos clínicos apresentados tinham como causa primária a dermatite atópica.
Apresentaram-se à consulta com lesões típicas da FBS, sendo que as pústulas e eritema eram as lesões predominantes. Chegou-se ao diagnóstico da FBS através da citologia dermatológica,
sendo que, em dois dos casos recorreu-se à cultura + teste de suscetibilidade. O plano
terapêutico dos pacientes for tratamento tópico à base de banhos e mousse e tratamento
sistémico com antibióticos. Como primeira abordagem, optou-se por uma antibioterapia empírica, amoxiciclina ácido-clavulânico e cefalexina. Apenas um dos casos, é que se optou
por um antibiótico de segunda geração, a minociclina. Em todos os casos adicionou-se ao
tratamento suplementos para melhorar a barreira cutânea.
Os casos de MRSP tem vindo a ser um desafio global, pois o uso indiscriminado de antibióticos tem vindo a aumentar os casos de resistência diminuindo as opções terapêuticas
para o maneio das infeções cutâneas.

This dissertation was written to complete the integrated Master’s Degree in Veterinary Medicine of Universiade Lusófona de Humanidades e Tecnologias and discusses Superficial Bacterial Folliculitis (SBF). A bibliographical review on the topic is included, as well as the presentation and discussion of five clinical cases collected at Hospital Veterinário Arco do Cego. Superficial bacterial folliculitis is an infection of the hair follicle caused by the organism Staphylococcus pseudintermedius, and is one of the main causes for prescription of antibiotics in small animal practice. SBF usually occurs secondary to a primary disease, the most common being of allergic origin, such as canine atopic dermatitis. The clinical cases presented with atopic dermatitis as the primary cause of SBF. They presented with typical lesions of SBF, with pustules and erythema were the predominant lesions. The diagnosis of SBF was made by dermatological cytology, and in two cases culture + susceptibility testing was used. The patients therapeutic plan was topical treatment based on baths and application of a mousse and systemic treatment with antibiotics. As a first approach, it was chosen for empirical antibiotic therapy was chosen with amoxicillin-clavulanic acid and cephalexin. There was only one case in which a second generation antibiotic, minocycline, was chosen. In all cases supplements to improve the skin barrier were added to the treatment. The cases of MRSP have become a global challenge, as the indiscriminate use of antibiotics has increased resistance and decreased the therapeutic options for the management of skin infections. Keywords: Staphylococcus pseudintermedius; superficial bacterial folliculitis; pustules; antibiotics; resistance
