Based on microscopic examination of the brains of seven wild-caught nurse sharks (Ginglymostoma cirratum), we observed a severe meningoencephalitis associated with numerous parasitic granulomas. The parasites were larval nematodes with morphological characteristics of the Superfamily Dracunculoidea. Although meningeal larval aggregates were associated with chronic inflammation, additional parasitic nodules found on the endocardial surface and perimandibular region did not provoke an inflammatory response. Neither the route of infection nor life cycle were determined.
基于对7条野生捕获的护士鲨（Ginglymostoma cirratum）大脑的显微镜检查，我们观察到一种严重的脑膜脑炎，伴有大量寄生性肉芽肿。寄生虫为幼虫线虫，具有龙线总科的形态特征。虽然脑膜幼虫聚集体与慢性炎症有关，但在心内膜表面和下颌周区域发现的其他寄生性结节并未引发炎症反应。感染途径和生命周期均未确定。
