Abstract
The family Cyathocotylidae trematode is a world-widely distributed parasite whose adults are mainly found in fish, reptiles, birds, and mammals in both freshwater and marine environments. However, little is known of the prevalence of these trematode in China. For the first time, we found Cyathocotylidae trematode in the Wuhu area. Therefore, we investigated the prevalence of metacercariae in Carassius auratus from Zhang Lake, Kui Lake, Qingyi River, and Yangtze River (Wuhu Section) in Wuhu area. A total of 392 one-year-old C. auratus were tested in January, April, July, and October 2019, respectively. After the fish were euthanized, the back, chest, and tail muscles were used for preliminary screening for the presence of metacercariae by direct compression method. Metacercariae were isolated by the artificial digestion method and then morphologically and molecularly identified by cox1 (642 bp) and ITS2 (418 bp) sequences amplification by PCR. Based on morphological features and sequence analysis, they were identified as cyathocotylid metacercariae. The four water sources have different degrees of prevalence throughout the year, the prevalence ranges from 28.45% (29/102) in Yangtze River to 50.55% (46/91) in Zhang Lake, with an average prevalence of 40.56% (159/392). There were also differences in the prevalence in different months: The highest occurred in July, which was 81.63% (80/98), while the lowest occurred in January, which was 8.89% (8/90). This study can provide basic data for the prevention and control of cyathocotylid trematode in this area.
