and are Erythrinidae family widely distributed in the Amazon River system of great value to both commercial and subsistence fishing for riverine populations. As such, the objective of the present study was to investigate the endoparasite communities of and of a tributary of the Amazon River in the north of Brazil. The endoparasite communities of and were taxonomically similar (85%) and consisted of sp., , () , sp. and , although the dominant endoparasite was , which was the most prevalent and abundant. All the specimens of both and were parasitized, with a total of 1237 helminths collected in the former host and 1151 helminths collected in the latter. possessed greater parasite species richness. Both hosts had an aggregate dispersion of parasites, and the abundance of sp. and correlated positively with the weight and length of the hosts. The condition factor was not affected by parasitism, but the abundance of and sp. increased when the condition factor of the hosts decreased. This is the first report of for and sp. for .
[鱼名1]和[鱼名2]属于Erythrinidae科，广泛分布于亚马逊河系统，对河流沿岸居民的商业捕鱼和自给性捕鱼都具有重要价值。因此，本研究的目的是调查巴西北部亚马逊河一条支流中[鱼名1]和[鱼名2]的体内寄生虫群落。[鱼名1]和[鱼名2]的体内寄生虫群落在分类学上相似（85%），包括[寄生虫名1]属、[寄生虫名2]、[寄生虫名3]（[寄生虫名3]的学名）、[寄生虫名4]属、[寄生虫名5]和[寄生虫名6]，尽管主要的体内寄生虫是[寄生虫名1]，它最为常见且数量最多。[鱼名1]和[鱼名2]的所有标本都被寄生，在前一种宿主中总共收集到1237条蠕虫，在后一种宿主中收集到1151条蠕虫。[鱼名1]拥有更丰富的寄生虫物种。两种宿主的寄生虫分布都呈聚集分布，并且[寄生虫名4]属和[寄生虫名5]的数量与宿主的体重和体长呈正相关。健康状况因子不受寄生影响，但当宿主的健康状况因子下降时，[寄生虫名6]和[寄生虫名4]属的数量增加。这是关于[鱼名1]感染[寄生虫名1]以及[鱼名2]感染[寄生虫名4]属的首次报告。
