Description and prevalence of Thynnascaris sp. larvae Dollfus, 1933 (Nematoda: Anisakidae) in Plagioscion squamosissimus Heckel, 1840 from Volta Grande Reservoir, State of Minas Gerais, Brazil

O presente trabalho teve por objetivo o estudo da helmintofauna da corvina de água doce Plagioscion squamosissimus, do reservatório de Volta Grande, MG, Brasil. Foram colhidos 68 peixes com comprimento médio de 25,2 cm e peso médio de 180,9 g, com rede de espera, bimestralmente no período de dezembro de 1995 a dezembro de 1996. Os parasitos foram cuidadosamente retirados de seus cistos que estavam aderidos ao mesentério intestinal. Os espécimes foram fixados em AFA a 65°C e conservados em álcool 70°GL contendo 5% de glicerina. Após diafanização com ácido acético ou lactofenol de Amann, 21 nematóides foram desenhados em câmara clara. As larvas foram identificadas como Thynnascaris sp. (Nematoda: Anisakidae). Das 68 corvinas examinadas, 30 estavam infectadas por esses parasitos com uma prevalência de 44,1%. O número médio de parasitos por hospedeiro foi de 0 a 13,8 e a intensidade média, de 0 a 16. A análise estatística, de acordo com o Teste Exato de Fisher, mostrou que a sazonalidade foi dependente da pluviosidade e temperatura do ar.

Death of two slender-billed parakeet (King) (Enicognathus leptorhynchus) (Aves, Psittacidae) by Ascaridia hermaphrodita (Froelich, 1789, Railliet & Henry, 1914) at the National Zoo of Santiago, Chile

No Zoológico Nacional do Parque Metropolitano de Santiago, Chile, foram encontrados dois psitacídeos Enicognathus leptorhynchus, mortos pelo nematódeo Ascaridia hermaphrodita (Froelich, 1789). Este é o primeiro registro desse nematódeo em E. leptorhynchus e também o primeiro registro deste parasito no Chile.

Injuries caused by scorpionfishes and (Scorpaena plumieri Bloch, 1789 Scorpaena brasiliensis Cuvier 1829) in the Southwestern Atlantic Ocean (Brazilian coast): epidemiologic, clinic and therapeutic aspects of 23 stings in humans

Fishes of the family Scorpaenidae are responsible for severe injuries and occasionally deaths in humans around the world. The more venomous fishes on the Brazilian coast and in the Southwestern Atlantic region are classified in the genus Scorpaena (family Scorpaenidae). However, there are few studies on the venomous apparatus, the effects of the venom, or clinical aspects of human envenoming provoked by Atlantic scorpionfishes.In this communication, the authors present 23 accidents caused by scorpionfishes of the genus Scorpaena among fishermen, and report the species that provoked the injuries, the circumstances of contacts, the clinical aspects observed and the therapeutic measures utilized for control of the symptoms of the victims. The intense pain and the systemic findings observed in the patients were very frequent and we think that the injuries provoked by scorpionfishes should be considered the most important manifestations caused by venomous fishes of the East Atlantic Ocean.

Espaços de exclusão e subjetividades do exílio: sobre Angu, de sangue, de Marcelino Freire

The paper aims to examine the work of Marcelino Freire, Angu de sangue (2000), from a poetic of identity with the black narratives and experiences of characters who participate in a space of exclusion, violence and social exile. Overall, the book deals with death and violence so raw and without idealizations. The characters struggle to survive in a cruel formo f life and denote the suffering and despair of those marked by peripheral situation. By proposing an analysis of tales of Angu de sangue, the work presented here reflects on a poetics of exclusion that runs the seventeen tales that make up the work in dialogue with images and internal references (through the images that illustrate the stories), and on the other hand, with pictures and references to the urban context of the excluded, represented on the pages of newspapers, magazines and television news.

Ultrastructure of the digestive tract in neotropical carnivorous catfish Hemisorubim platyrhynchos (Valenciennes, 1840) (Siluriformes, Pimelodidae)

The surface of the digestive tract of Hemisorubim platyrhynchos was analyzed by scanning electron microscopy. Morphometric studies by transmission electron microscopy were performed to analysis the intestinal microvilli. H. platyrhynchos is a Neotropical carnivorous freshwater catfish featuring a short digestive tract composed of a short esophagus, saccular stomach, and intestine with four regions: anterior, middle, posterior, and rectal. The esophageal surface is constituted by fingerprint-like microridges that anchor the mucosubstances secreted by goblet cells facilitating the passage of food. Goblet cells present the opening to the esophageal lumen, between the microridges. Club cells are in basal epithelium and they do not present the opening to the lumen. The gastric luminal surface shows polygon-shaped epithelial cells which secrete granules by exocytose to protect the gastric surface. The intestinal luminal surface reveals folds that are thicker in the anterior intestine than in the posterior intestine, increasing the absorptive surface area. The intestinal surface presents the microvilli of enterocytes and the opening of goblet cells. The morphometric analysis showed that the microvilli are longer in the anterior intestine, significantly decreasing towards the posterior intestine. The microvilli surface area significantly is greater in the anterior and middle intestine than in the posterior intestine. Numerous openings of goblet cells were observed in the posterior intestine acting in epithelial protection and lubrication. SCANNING 9999:1-8, 2015. © 2015 Wiley Periodicals, Inc.
