Abstract:
Ergasilus lizae Krøyer, 1863 is a parasitic copepod known to infect mullets (Mugilidae) in different parts of the world. It was originally reported from the east coast of North America, but the original description lacks enough detail, making identification with this information difficult. In this study, we provide a redescription of E. lizae found on Mugil curema Valenciennes and M. cephalus Linnaeus, caught in two coastal lagoons of northwestern Mexico during two climatic seasons: warm/rainy and cold/dry. The prevalence of this parasite was higher in the warm season than in the cold season. To facilitate the species identification, new sequences of the barcoding gene (COI mtDNA) of E. lizae were generated and compared against unpublished sequences of E. lizae available in the Barcode of Life Database (BOLD). Our results suggest that the sequences of BOLD possibly belong to a species misidentified as E. lizae.
摘要:
ErgasiluslizaeKrøyer,1863年是一种寄生co足类动物,已知会感染世界不同地区的鱼(Mugilidae)。它最初是从北美东海岸报道的,但是最初的描述缺乏足够的细节,很难识别这些信息。在这项研究中,我们提供了在MugilcuremaValenciennes和M.cephalusLinnaeus上发现的E.lizae的重新描述,在两个气候季节,墨西哥西北部的两个沿海泻湖中被捕:温暖/多雨和寒冷/干燥。这种寄生虫在温暖季节的患病率高于寒冷季节。为了便于物种识别,产生新的李泽兰的条形码基因序列(COImtDNA),并与生命条形码数据库(BOLD)中未公开的李泽兰序列进行比较。我们的结果表明,BOLD的序列可能属于被误认为是E.lizae的物种。
