RESUMO
This paper describes the in vivo Bronchoalveolar lavage (BAL) technique by endoscopy in tapirs (Tapirus terrestris) with clinical signs of tuberculosis. The technique was performed in two tapirs, male and female, from Curitiba Zoo, Paraná, Brazil. A flexible endoscope and a polyethylene catheter were used after the chemical restraint of the animals. For BAL technique, 60mL of saline 0.9% were infused with a polyethylene catheter, introduced by the endoscope's working channel, and 15mL of BAL were recovered, analyzed and submitted to cytocentrifugation. Slides were stained by Papanicolaou, periodic acid-Schiff (PAS) and Ziehl-Neelsen methods contained high quantity of inflammatory cells on light microscopy (macrophages 27.5%, lymphocytes 0.5%, neutrophis 67% and eosinophis 5%). BAL samples were submitted to culture, bacilloscopy and PCR and were negative for both animals. Based on this study, it was concluded that the bronchoalveolar lavage technique in tapirs is feasible, simple, noninvasive, practical and fast, providing an important clinical information in vivo regarding the functional status of the lower respiratory tract...
O presente trabalho descreve a técnica de lavado broncoalveolar (LBA) por endoscopia em antas (Tapirus terrestris) in vivo com sinais clínicos de tuberculose. A técnica foi realizada em duas antas, um macho e uma fêmea, provenientes do Zoológico de Curitiba, Paraná, Brasil, utilizando-se endoscópio flexível e sonda de polietileno, após a contenção química desses animais. Para o LBA, 60mL de solução fisiológica 0,9% foram infundidos com auxílio de cateter de polietileno, introduzido pelo canal de trabalho do endoscópio, e, aproximadamente, 15mL de LBA foram recuperados, acondicionados, analisados e submetidos à citocentrifugação. As lâminas foram coradas pelas técnicas de Papanicolau, ácido periódico de Schiff (PAS) e Ziehl- Neelsen, método que contém altas quantidades de células inflamatórias em microscopia (macrófagos 27,5%, linfócitos 0,5%, neutrófilos 67% e eosinófilos 5%). Amostras de LBA foram submetidas a cultura, baciloscopia e PCR e foram negativas em ambos os animais. Concluiu-se, baseado no presente trabalho, que técnica de lavado broncoalveolar é simples, não invasiva, funcional e rápida. Pode fornecer ao clínico importantes informações acerca do estado de funcionamento do aparelho respiratório in vivo...

Captive adult male ocelots (Leopardus pardalis, n = 3), margays (L. wiedii, n = 3) and tigrinas (L. tigrinus, n = 4) in two locations in southern Brazil were studied for 14 consecutive months to evaluate the effect of season on testicular function. Reproductive evaluations, including testicular measurements, electroejaculation and blood collection were conducted monthly. Fecal samples were collected weekly for androgen metabolite analysis to assess testicular steroidogenic activity. Ocelots had the highest number of motile spermatozoa in the ejaculate (114.7+/-15.8 x 10(6); P < 0.05), the highest percentage of morphologically normal spermatozoa (82.4+/-1.2%; P < 0.05) and the highest concentration of fecal androgens (1.71 vs. 0.14 microg/g; P < 0.05). Margays and tigrinas had lower numbers of motile spermatozoa (23.4+/-2.8 x 10(6), 74.2+/-8.9 x 10(6), respectively), lower percentages of morphologically normal spermatozoa (57.4+/-2.8, 59.2+/-3.5%, respectively), and lower fecal androgen concentrations (0.15+/-0.01, 0.23+/-0.01 microg/g, respectively). Serum testosterone concentrations were similar among the three species. Fecal androgen concentrations were not affected by season, with the exception of the ocelot where concentrations were higher (P < 0.05) in the summer. Ejaculates were collected throughout the year; however, peaks in average sperm production were observed during the summer for all species. In summary, this study has identified several species differences in male testicular traits among ocelots, margays and tigrinas. Results of longitudinal reproductive assessments suggest males of each species are capable of breeding throughout the year.
