Abstract(s)
A ecografia não é um método de diagnóstico habitual em patologia respiratória em caprinos. No entanto, poderá constituir uma ferramenta relativamente simples e útil para detetar determinadas doenças e mais rapidamente se instituírem medidas terapêuticas e profiláticas adequadas. Nos pequenos ruminantes o exame ecográfico ao tórax é útil para demonstrar hidro ou piotórax, abcessos pulmonares com extensão à pleura e consolidação pulmonar associada a pneumonias víricas ou bacterianas.
Foi examinado clinicamente uma fêmea adulta com um quadro de tosse crónica e emaciação
progressiva e sujeita a exame ecográfico com um equipamento Aloka Echo – Camara SSD% 500 e uma sonda de 5 MHz segundo os procedimentos previamente descritos.
Ao exame ecográfico visualizaram-se pequenas estruturas hiperecogenicas com aproximadamente 1 mm de diâmetro difusas por todo o parênquima pulmonar e hepático. Procedeu-se à eutanásia do animal e posterior necropsia onde se visualizaram granulomas miliares no parênquima pulmonar e hepático. Foram recolhidas amostras para exame microbiológico (congeladas a E20oC) e histológico (fixadas em formol a 10%).
Para o exame microbiológico, as amostras de pulmão e fígado foram enviadas para o LNIV E Lisboa, onde foram processados de acordo com as recomendações da OIE (2008). A identificação das espécies de micobactérias isoladas foi baseada em PCREREA. Foi isolado Mycobacterium caprae. spoligotipo SB0157. O exame histológico revelou a presença de uma pneumonia granulomatosa, tendo-se visualizado bacilos álcool-ácido resistentes. Neste trabalho, os autores utilizam, pela primeira vez, a ecografia no diagnóstico ante morte de tuberculose num caprino, associada aos métodos convencionais de diagnóstico pós morte. Os resultados demonstram a utilidade do exame ecográfico como primeiro método de diagnóstico de lesões granulomatosas, compatíveis com tuberculose. Por outro lado, sendo um método rápido, poderá conduzir a medidas sanitárias precoces, o que poderá ser decisivo na luta contra a tuberculose.
Ultrasound is not a usual method of diagnosis in respiratory disease in goats. However, it may be a relatively simple and useful tool for detecting certain diseases and more quickly establish appropriate therapeutic and prophylactic measures. In small ruminants, ultrasound is useful to demonstrate hydro or pyothorax, lung abscesses extending to the pleura and lung consolidation associated with viral or bacterial pneumonia. Ultrasound examination was performed to an adult female with emaciation and chronic, progressive cough with an equipment Aloka Echo – Camara SSDE 500 and a 5 MHz probe, according to previously described procedures. Small hyperechogenic structures of approximately 1 mm diameter diffuse across the lung and liver parenchyma were noted. At necropsy, miliar granulomas were seen in lung and liver parenchyma. Samples for microbiological examination (frozen at E20 ° C) and histology (fixed in 10% formalin) were collected. For microbiological examination, samples of liver and lung were sent to the LNIV E Lisbon, where they were processed in accordance with the recommendations of the OIE (2008). Identification of mycobacteria was based on PCREREA. Mycobacterium caprae spoligotipo SB0157 was isolated. Histological examination revealed the presence of a granulomatous pneumonia, with acidEfast bacilli. In this paper, the authors used, for the first time, the ultrasound in the diagnosis ante mortem of tuberculosis in a goat associated with conventional post mortem diagnosis methods. The results demonstrate the utility of ultrasound technique as an initial method of diagnosis of granulomatous lesions compatible with tuberculosis. On the other hand, being a fast method, can lead to early health measures, which could be decisive in the fight against tuberculosis.
