Abstract. An uncommon disseminated Mycobacterium tuberculosis infection is described in a 12-year-old female dog presenting with fever, dyspnea, cough, weight loss, lymphadenopathy, melena, epistaxis, and emesis. The dog had a history of close contact with its owner, who died of pulmonary tuberculosis. Radiographic examination revealed diffuse radio-opaque images in both lung lobes, diffuse visible masses in abdominal organs, and hilar and mesenteric lymphadenopathy. Bronchial washing samples and feces were negative for acid-fast organisms. Polymerase chain reaction (PCR)-based species identification of bronchial washing samples, feces, and urine revealed M. tuberculosis using PCR-restriction enzyme pattern analysis-PRA. Because of public health concerns, which were worsened by the physical condition of the dog, euthanasia of the animal was recommended. Rough and tough colonies suggestive of M. tuberculosis were observed after microbiological culture of lung, liver, spleen, heart, and lymph node fragments in Lö wenstein-Jensen and Stonebrink media. The PRA analysis enabled diagnosis of M. tuberculosis strains isolated from organs.
RESUMO A Mastite em éguas é considerada uma doença rara sendo o Streptococcus equi. Staphylococcus sp., Corynebacterium sp., Actinobacillus sp., Nocardia sp. e as enterobacterias os micro-organismos mais frequentemente envolvidos. A doença está relacionada a injúrias e traumas nas mamas e tetos. Edema e fibrose da glândula mamária, leite com aspecto viscoso ou muco-purulento são observados nos casos de mastite clínica. O diagnóstico é baseado no exame clínico da mama associado ao cultivo microbiológico do leite. Os métodos indiretos para o diagnóstico de mastite subclínica como California Mastits Test e Contagem de Células Somáticas não são padronizados para a espécie em questão. A terapia para a mastite equina é baseada no uso sistêmico de antimicrobianos, com base nos resultados obtidos no teste “in vitro” de sensibilidade microbiana. Não há medidas de controle específicas para a mastite equina. Objetivou-se neste estudo revisar os principais aspectos relacionados a mastite em éguas com ênfase na etiologia, epidemiologia, sinais clínicos, diagnóstico, tratamento, medidas de controle e profilaxia.
