This study reports the occurrence of metacercariae of Austrodiplostomum compactum in Pimelodus platicirris from a Neotropical reservoir in the Grande River, SP, Brazil. A total of 164 fish were collected, of which 12.80% were infected with metacercariae in the eyes. The mean intensity of infection and mean abundance were 1.52±0.14 (1‒3) and 0.23±0.05 (0‒3), respectively. The presence of this parasite with a high intensity of infection can cause exophthalmos, retinal displacement, opacity of the lens, blindness or even death. This is the first record of ocular metacercariae for P. platicirris, thus increasing the number of hosts for A. compactum.
本研究报告了在巴西圣保罗格兰德河一个新热带水库的扁吻魾(Pimelodus platicirris)中发现紧密澳双穴吸虫(Austrodiplostomum compactum)囊蚴的情况。共采集了164条鱼,其中12.80%的鱼眼部感染了囊蚴。平均感染强度和平均丰度分别为1.52±0.14(1 - 3)和0.23±0.05(0 - 3)。这种高感染强度的寄生虫的存在可导致眼球突出、视网膜移位、晶状体混浊、失明甚至死亡。这是扁吻魾眼部囊蚴的首次记录,从而增加了紧密澳双穴吸虫的宿主数量。
