E-mail: reginacrpaz@gmail.com The pampas cat Leopardus colocolo (Molina, 1782) is a species of the Felidae family, widely distributed in South America, included on CITES Appendix II and classified as Near Threatened on the IUCN Red List, with population trend decreasing. Based on this information, the objective of this study is to describe morphologically the testes and epididymal ducts of pampas cat. The animal, coming from the Federal University of Mato Grosso Zoo, Brazil, had died after anesthesia procedure and the male reproductive system was dissected to collect the testicles. The samples taken were fragmented and histologically examined. From the microscopic analysis of the testes were identified: vaginal and tunica albuginea, formed by dense connective tissue modeled with large amount of collagen fibers. The tunica albuginea fibrous septa emits into the body. The seminiferous tubules are coiled and coated internally by spermatogenic epithelium consisting of Sertoli cells, surrounded by a basement membrane in the presence of myoid cells. The interstitial tissue between the seminiferous tubules, is composed of loose connective tissue, blood and lymph vessels, and Leydig cells in polyhedral shape. The epididymal ducts showed pseudostratified columnar epithelium with secretory cells of which stereocilia design, situated on a basement membrane filled by myoid cells. This epithelium has principal and basal cells, the main cell design stereocilia toward the lumen of the epididymal duct.

RESUMO.- Mehanna M., Ferreira A.L.S., Ferreira A. & Paz R.C.R. 2016. Morphology of the testes and epididymal ducts in the Pampas cat Leopardus colocolo (Molina, 1782). [Morfologia dos testículos e ductos epididimários do gato-palheiro Leopardus colocolo (Molina, 1782).] Pesquisa Veterinária Brasileira 36(10):1014-1020. Laboratório de Pesquisa em Animais de Zoológico, Faculdade de Agronomia, Medicina Veterinária e Zootecnia, Universidade Federal de Mato Grosso, Avenida Fernando Corrêa da Costa 2367, Bairro Boa Esperança, Cuiabá, MT 78060-900, Brazil. E-mail: reginacrpaz@gmail.com O gato-palheiro Leopardus colocolo (Molina, 1782) é uma espécie da família Felidae, com ampla distribuição na América do Sul. Está incluido no Appendix II da CITES e classificada como Próxima da Extinção na Lista Vermelha da IUCN, apresentando população em decrescimo. Com base nessas informações o objetivo deste estudo é caracterizar morfologicamente os testículos e ductos epididimários de L. colocolo. O animal, oriundo do Zoológico da Universidade Federal de Mato Grosso, Brasil, veio a óbito após procedimento anestésico e o sistema reprodutor masculino foi dissecado para coleta dos testículos. As amostras retiradas foram fragmentadas e histologicamente examinadas. A partir das análises microscópicas dos testículos foram identificados: a túnica vaginal e albugínea, formada por tecido conjuntivo denso modelado, com grande quantidade de fibras de colágeno. A túnica albugínea emite septos fibrosos para o interior do órgão. Os túbulos seminíferos são enovelados e revestidos internamente por epitélio estratificado constituído por células espermatogênicas e células somáticas de Sertoli, envolvidos por uma membrana basal com presença de células mioides. O tecido intersticial, entre os túbulos seminíferos, é constituído de tecido conjuntivo do tipo frouxo com vasos sanguíneos e linfáticos, e células de Leydig em formato poliédrico. Os ductos epididimários apresentaram epitélio cilíndrico pseudoestratificado com células secretoras dos quais projetam estereocílios, situados sobre uma membrana basal repleta por células mióides. Este epitélio apresenta células principais e basais, cujas células principais projetam estereocílios em direção ao lúmen do ducto epididimário.

E-mail: vetjrossi@gmail.com The development of dentistry is delayed in the preventive internal medicine for wild animals. Some international papers about wild animal dentistry have already been published regarding some species in wild life or kept in captivity in different geographical regions, but not specifically about the great neotropical felines Panthera onca and Puma concolor. The aim of this study was to survey the prevalence of malocclusion in neotropical felines maintained in the state of São Paulo. For the study a sample of 42 jaguars (Panthera onca) and 36 pumas (Puma concolor) was used, totalizing 78 animals, proceeding from 18 institutions where such species were kept in captivity. All animals were examined if the occlusion was in accordance with the normal for the species. The teeth were identified one by one, examined directly by means of a dental explorer. Malocclusion was present in 47.61% (20 cases) in Panthera onca, and in 5.55% (2 cases) of Puma concolor. The animals with malocclusions apparently did not have problems of food apprehension or chewing ability, although they presented a more reduced interproximal space, with food accumulation the lack of removal of which could provoke oral problems.

Prof. Dr. Orlando de Marques de Paiva 87, Bloco 8-superior, Cidade Universitária, São Paulo, SP 05508-000, Brazil. E-mail: vetjrossi@gmail.com The aim was to survey the main oral lesions related with periodontal disease of jaguars, Panthera onca, living in captivity or in the wild, as conservation of threatened animals from extinction, as in case of the jaguar, and the preservation of such species in free life may be determined by environmental conditions which can influence oral health. Forty-two jaguars (P. onca) kept in captivity in 18 institutions in the state of São Paulo were studied. The animals to be examined were anesthetized by the Plan of Neotropical Handling of Felids. Additionally, 4 jaguars (P. onca) proceeding from wild life were captured for the study on Farm Sete, municipality of Miranda, Mato Grosso do Sul, in the southern Pantanal. All animals surveyed in captivity showed various degrees of oral lesions related to periodontal disease. The animals living in the wild did not present any clinical signs of oral lesions.
