E-mail: silng@uol.com.br An anatomopathologic study of 130 captivy psittacines from zoos, breeders and rehabilitation centers showed the presence of neoplastic disease in seven birds, totalizing 5.4% of the cases. The neoplasms were identified like cholangiocarcinoma, cholangioma, lymphoma, haemangiosarcoma and renal cell carcinoma. The cholangiocarcinoma was the tumor most commonly observed. it was present in birds. This study describes the macro and microscopic findings of these tumors; also reports diagnostic methods employed to identify these neoplasms.

Luiz de Camões 2090, Lages, SC 88520-000, Brazil. E-mail: fonteque@cav.udesc.br The poisonous snakes of the genera Crotalus and Bothrops have been kept in captivity with the purpose of extracting poison for the production of immunobiological. Knowledge of the physiology of these animals and serum proteins concentration changes are important for early identification of major diseases which lead to states of hypoproteinemia and hyperproteinemia. The objective was to determine the concentration of total protein and serum protein electrophoresis profile of Crotalus durissus terrificus (rattlesnake) in captivity. Blood samples were taken from the ventral coccygeal vein of 21 adult and healthy snakes divided into groups: Group 1 with 12 males, weighing in average 588.89±193.55g, and Group 2 with nine females, weighing in average 708.33±194.04g. The total serum concentration of protein was determined by the method of refractometry and agarose gel electrophoresis. The total protein values in the serum for females was 4.82±0.72, for males 4.51±0.50 and males and females 4.64±0.61, identified by four fractions (g/dL): albumin, a, b and g-globulin. Additionally the albumin/globulin ratio was calculated. The female snakes showed higher values for the variables, albumin and the albumin/globulin (AG) differed significantly (P<0.05) from the group of male snakes, but there was no clinical significance.

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.

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.

Abstract in English:

The objective of this study was to determine the attack rate of vampire bats, Desmodus rotundus (Geoffroy, 1810), on cattle kept in captivity. It was observed that the bats returned to wounds previously made by them, but without a rigorous pattern of repetition. New wounds were made almost everyday, while old wounds were temporarily or definitively abandoned. Vampire bats fed on all regions of the body, although showed preference for the front legs, dorsal region, hind legs and withers. Finally, a great number of wounds were opened, whereas only a few were utilized on the sarne night.

Abstract in Portuguese:

O objetivo deste estudo foi determinar a taxa de ataque de morcegos hematófagos Desmodus rotundus alimentando-se em bovinos mantidos em cativeiro. Observou-se que os morcegos retornam aos ferimentos por eles provocados anteriormente, porém sem um padrão rigoroso de repetitividade. Eles abrem novos ferimentos quase que diariamente e abandonam temporária ou definitivamente outros. Os morcegos sugaram em todas as regiões corporais dos bovinos, mas preferencialmente nos membros anteriores, dorso, membros posteriores e cernelha. Finalmente, causam um grande número de ferimentos nos animais, apesar de utilizarem poucos deles por dia.
