Abstract

The stomachs of 100 free-ranging black caimans (Melanosuchus niger Spix, 1825) from the Mamirauá Sustainable Development Reserve, Amazonas state, Brazil, were examined for parasitism and pathologic lesions. All animals were harvested for human consumption. Ascaridoid nematodes were found in 67 caimans and were identified as Brevimulticaecum sp. These parasites were associated with focally extensive, chronic gastric ulcers and formation of localized intramural granulomas containing nematodes. All caiman were in good nutritional condition, which suggests that effects of gastric nematodiasis on the crocodilian hosts were minimal at the time of slaughter.

摘要

对来自巴西亚马孙州马米拉瓦可持续发展保护区的100只自由放养的黑凯门鳄（Melanosuchus niger Spix，1825）的胃部进行了寄生虫感染和病理损伤检查。所有动物均被捕获以供人类食用。在67只凯门鳄中发现了蛔虫类线虫，并鉴定为短多盲囊线虫属（Brevimulticaecum sp.）。这些寄生虫与局部广泛的慢性胃溃疡以及含有线虫的局部壁内肉芽肿形成有关。所有凯门鳄营养状况良好，这表明在屠宰时胃线虫病对鳄鱼宿主的影响最小。
