RESUMO

Background: Wild and captivity monkeys are infested by several parasites species, mainly, Strongyloides sp. and Acanthocephala sp, which has been identifi ed as the major causes of illness and death. However, Molineus torulosus is a pathogenic nematode found in Neotropical New World Primates and causes severe illness in small primates due to severe gastrointestinal injury. In South America, the parasite was described in Cebus apella and C. olivecaeus from French Guyana and were verifi ed the occurrence in tropical forests. Thus, it is the fi rst report about M. torulosus infestation in capitivity capuchin monkeys in Brazil.Case: Two capuchin monkeys were presented for necropsy. According to veterinarian the monkeys had about fi ve years old and weighed 0.9 kg and lived in a particular park in urban with 20 to 30 capuchin monkeys group. The veterinarian described that six capuchin monkeys were found dead in two months period. One of the monkeys were found dead and another one had respiratory disturbance, apathy, prostration, cyanotic mucosa, feces with green coloration and death after four days in observation and isolation of the group. Necropsy confi rmed emaciation and moderate splenomegaly, great amount of fibrin on the intestine and presence of multifocal 1 to 2 cm nodules in small intestine with numerous parasites mainly initial portion.

RESUMO

The experiment aimed to evaluate the effects of diets without micro minerals and vitamins, reduced inorganic phosphorus levels and phytase addition in bone metabolism and renal and hepatic functions in finishing pigs. Forty eight 105-day old females were randomly allotted in six groups: standard diets (T1), composed of corn, soybean meal and wheat meal; standard ration without micro mineral and vitamin supplement (T2); T2 ration with phytase (T3) T2 ration reducing 1/3 of inorganic P with phytase (T4), T2 ration reduced 2/3 of inorganic P with phytase (T5) and T2 ration with complete reduction of inorganic P with phytase (T6). The experiment was carried out in two phases: phase 1: 24 animals slaughtered at 150 days of age (106.65 kg); and phase 2: 24 animals slaughtered at 175 days of age (123.87 kg). The serum parameters evaluated were: total and ionic calcium, phosphorus, calcium/phosphorus ratio, total protein, albumin, AST, GGT, alkaline phosphatase, urea and creatinine. All biochemical parameters were analyzed using commercial kits in an automatic analyzer. The levels obtained for all analyzed parameters ranged within normal established values for this species and age. Inorganic phosphorus decrease in phytase-added diets did not interfere in bone metabolism. Vitamin and mineral supplements withdrawal and progressive decrease of inorganic phosphorus and phytase addition in

RESUMO

The present experiment aimed to evaluate histological changes in hepatic, renal, thyroid, parathyroid and metacarpian bone tissues of pigs submitted to diets without micro minerals and vitamins, reduced inorganic phosphorus levels and phytase addition in two restriction times. Forty eight 105-days old (66.15±0.14 kg) female pigs received experimental diets with corn, soybean and wheat meal. The animals were randomly distributed in six groups: standard diets (T1); composed of corn, soybean meal and wheat meal; standard ration without micro mineral and vitamin supplement (T2); T2 ration with phytase (T3); T2 ration reducing 1/3 of inorganic phosphorus with phytase (T4); T2 ration reduced 2/3 of inorganic phosphorus with phytase (T5); and T2 ration with complete reduction of inorganic phosphorus with phytase (T6). The experiment was carried out in two phases: Phase 1. 24 animals, 35 days of restriction and slaughter at 150 days of age (106.65 kg), and Phase 2, 24 animals, 60 days of restriction and slaughter at 175 days of age (123.87 kg). At slaughter, samples of liver, kidney, thyroid, parathyroid and metacarpian bone were collected from all animals. The samples were fixed in 10% buffered formaldehyde and stained by hematoxilin and eosin (HE). The Mallorys trichrome stain was used in bone sections. Kidney histopathological evaluation showed interstitial nephritis in 37 animals

RESUMO

A tireoidite linfocítica é uma enfermidade auto-imune e uma das principais afecções tireoidianas, responsáveis por causar hipotireoidismo primário em cães. O presente trabalho relata o caso de um canino, Bull terrier, macho, de dois anos de idade e histórico de morte súbita durante exercício em esteira. À macroscopia, as alterações relevantes compreenderam congestão e edema pulmonar e endocardiose de mitral. Ao exame microscópico foram verificadas endocardiose, aterosclerose em vasos de diversos órgãos e, na tireóide, constatou-se tireoidite linfocítica. O exame anatomopatológico compreendeu ferramenta decisiva na descrição das alterações e conclusão do diagnóstico, visto que não havia diagnóstico prévio da enfermidade.
