E-mail: garciajuanagustin@hotmail.com A retrospective analysis (2000 to 2013) of cattle poisoning caused by toxic plants and other compounds was carried out in the Pampas region of Argentina by the Animal Health Group of INTA-EEA, Balcarce. During this period, 1263 reports of diseases of different etiologies (infectious, parasitic, toxic, metabolic and miscellaneous) were recorded in cattle, by collecting anamnestic, clinical and pathological information. A toxic etiology was diagnosed in 21.1% of these reports. Iatrogenic poisoning caused by ionophores was the most frequently recorded etiology. Consumption of toxic plants (Wedelia glauca, Solanum glaucophyllum, among others), mycotoxins (Claviceps purpurea, Claviceps paspali, Epichloë coenophiala, among others), and plants producing cyanide and nitrates/nitrites were also commonly diagnosed. The high frequency of toxic episodes and the difficulties in their diagnosis by practitioners in our livestock production systems emphasizes the importance of this report.

ABSTRACT.- Margineda C.A., Odriozola E., Moreira A.R., Cantón G., Micheloud J.F., Gardey P., Spetter M. & Campero C.M. 2013. Atypical actinobacillosis in bulls in Argentina: granulomatous dermatitis and lymphadenitis. Pesquisa Veterinária Brasileira 33(1):1-4. Instituto Nacional de Tecnología Agropecuaria (INTA), Estación Experimental Agropecuaria Balcarce, Ruta 226 Km 73,5 (7620) Balcarce, Argentina. E-mail: eodriozola@balcarce.inta.gov.ar Actinobacillosis is a common cause of sporadic infection in cattle. It was mostly characterized as a pyogranulomatous inflammation of the tongue, but also soft tissues as lymph nodes, other digestive tract localization and skin. The aim of this study was to describe an episode of granulomatous dermatitis and lymphadenitis affecting a bull herd in Argentina during 2010. Actinobacillus lignieresii was isolated from samples collected from one of the affected bulls, and characteristic lesions were observed. Lesions other than ‘wooden tongue’ are usually uncommon; however, actinobacillosis should be included as a differential diagnosis for cutaneous diseases.

RESUMO.- Margineda C.A., Odriozola E., Moreira A.R., Cantón G., Micheloud J.F., Gardey P., Spetter M. & Campero C.M. 2013. Atypical actinobacillosis in bulls in Argentina: granulomatous dermatitis and lymphadenitis. [Actinobacilose atípica em touros na Argentina: dermatite granulomatosa e linfadenite.] Pesquisa Veterinária Brasileira 33(1):1-4. Instituto Nacional de Tecnología Agropecuaria (INTA), Estación Experimental Agropecuaria Balcarce, Ruta 226 Km 73,5 (7620) Balcarce, Argentina. E-mail: eodriozola@balcarce.inta.gov.ar A actinobacilose é causa comum de infecções esporádicas em bovinos. Esta afeção tem sido caracterizada como uma infecção piogranulomatosa não somente da língua como também de tecidos moles tais como linfonodos, ou outras localizações no trato digestivo e na pele. O objetivo do presente trabalho é descrever um episódio de dermatite piogranulomatosa e linfadenite que afetou um rebanho de touros na Argentina em 2010. As amostras recolhidas de um dos animais afetados permitiram o isolamento de Actinobacillus lignieresii. Observaram-se as lesões características da doença. Habitualmente não são comuns outras lesões para além das descritas como “língua de pau”, no entanto, a actinobacilose deve ser incluída como um possível diagnóstico diferencial de doenças cutâneas.
