ABSTRACT
A gota úrica visceral é uma doença que acomete répteis, aves e mamíferos. Caracteriza-se por depósitos de cristais de urato e ácido úrico em diferentes órgãos da região visceral. O objetivo deste trabalho foi relatar um caso de gota úrica visceral em um indivíduo de bobo-pequeno (Puffinus puffinus) encontrado morto no litoral norte de Santa Catarina, sul do Brasil. No período de 20 de agosto de 2015 a 20 de abril de 2016, as praias dos municípios de Araquari, Barra do Sul, São Francisco do Sul e Itapoá foram monitoradas diariamente para o registro e a recuperação de tetrápodes marinhos mortos, incluindo aves marinhas. Foram encontrados e necropsiados 84 indivíduos. Um deles apresentou o pericárdio aderido ao miocárdio e com a coloração esbranquiçada. Os rins, o fígado e os pulmões continham inúmeros pontos esbranquiçados. A ocorrência dessa patologia na espécie foi de 1,19%. Trata-se do primeiro relato de bobo-pequeno com gota úrica visceral encontrado no Brasil.(AU)
Visceral gout uric is a disease that affects reptiles, birds and mammals. It is characterized by urate crystal deposits and uric acid in different organs of visceral region. The objective of this study was to report a case of visceral urica drop in a manx shearwater individual (Puffinus puffinus) found dead on the north coast of Santa Catarina, Southern Brazil. In the period from 20 August 2015 and 20 April 2016, beaches in the municipalities of Araquari, Barra do Sul, São Francisco do Sul and Itapoá, were monitored daily for the registration and recovery of dead marine tetrapods, including seabirds. Eighty-four were found and necropsied. One of them was whitish in color and had the pericardium adhered to the myocardium. The kidneys, liver and lungs contained numerous whitish dots. The occurrence of this disease in the species was 1.19%. This is the first manx shearwater report with visceral urica drop found in Brazil.(AU)

Pontoporia blainvillei (Gervais and d'Orbigny, 1844) is an endangered small cetacean endemic to South America with four Franciscana Management Areas (FMA) recognized as different population stocks. The role of the intestinal parasite Synthesium pontoporiae (Digenea: Brachycladiidae) as a possible biological marker to differentiate P. blainvillei stocks was evaluated using nuclear and mitochondrial DNA markers. Internal transcribed sequence 1 and 2 (ITS1 and ITS2) regions of S. pontoporiae did not show intraspecific variability. The mitochondrial NADH dehydrogenase subunit 3 (ND3) and cytochrome oxidase subunit I (COI) gene sequences suggested lack of population structure in S. pontoporiae and population expansion. The apparent panmixia of S. pontoporiae may be due to the high mobility of one or more of its intermediary hosts. Alternatively, it may be due to the small sample size. This result is incongruent with the previously proposed FMA.
