Abstract

Neobenedenia melleni (MacCallum, 1927) is a widely spread pathogen in teleost maricultures with a very low host specificity. Between July of 2006 to June of 2007, 120 specimens of Trichiurus lepturus Linnaeus, 1758 were acquired of local fishermen in the Guanabara Bay (22 degrees 57' S and 42 degrees 41' W), State of Rio de Janeiro, Brazil, to the study of the parasite fauna. The surface of the host body was scraped and the monogeneans obtained were identified as N. melleni, which showed prevalence of 8.3% and mean intensity of infection 1.2+/-0.42. Data about morphology of the specimens collected were included herein. Neobenedenia melleni is recorded by the first time parasitizing on a wild host from the Brazilian coastal zone.

摘要

梅氏新贝尼登虫（MacCallum，1927年）是硬骨鱼海水养殖中广泛传播的一种病原体，宿主特异性极低。2006年7月至2007年6月期间，从巴西里约热内卢州瓜纳巴拉湾（南纬22度57分，西经42度41分）的当地渔民处采集了120尾1758年命名的带鱼样本，用于研究寄生虫区系。刮取宿主鱼体表，所获单殖吸虫被鉴定为梅氏新贝尼登虫，其感染率为8.3%，平均感染强度为1.2±0.42。本文还纳入了所采集样本的形态学数据。梅氏新贝尼登虫首次被记录寄生在巴西沿海区域的野生宿主上。
