摘要
鼹鼠蟹(Emerita analoga)生活在太平洋海岸的沙滩上,是各种种群的主要食物来源,尤其是滨鸟。据报道,沿着秘鲁海岸,类似木螺是一种供人类食用的水生生物资源,由于其作为不同寄生虫群的中间宿主的作用,这引起了潜在的公共卫生问题。本研究的目的是确定类似性大肠杆菌的流行率和寄生负荷,以及与性别和头胸长度(LC)的关系。该研究于2023年10月和11月在Mollendo海滩环路(秘鲁阿雷基帕)进行。结果发现,在548个样本中,51.64%的个体被感染,且LC尺寸较大,其中雌性个体的平均尺寸较大(x′= 20.06 mm)。Fisher的测试显示性别和寄生虫感染之间没有显著差异;然而,LC和感染之间存在显著差异(r = 0.32, p < 0.001),尤其是在女性中(r = 0.31, p < 0.001)。共鉴定出2种寄生虫,分别为棘头目(Profilicollis altmani)和线虫目(Proleptus sp.),分别占41.61%和4.74%。在当地人口中进行的一项调查突出表明,目前在捕鱼和人类消费(例如,煎蛋卷和酸橘汁腌鱼)中使用类似肠虫,鉴于发现50%以上的人受到感染,这增加了健康风险。
Prevalence and parasitic load in Emerita analoga “Muymuy” on the beaches of Mollendo (Arequipa), Southern Peru
The mole crab, Emerita analoga, is found on the sandy beaches of the Pacific coast and is the primary food resource for various populations, particularly shorebirds. Along the Peruvian coast, E. analoga has been reported as a hydrobiological resource used for human consumption, which raises potential public health concerns due to its role as an intermediate host for different groups of parasites. The aim of this study was to determine the prevalence and parasitic load in E. analoga, as well as the relationship with sex and cephalothorax length (LC). The study was conducted on the Mollendo beach circuit (Arequipa, Peru) during October and November 2023. It was found that of the 548 E. analoga individuals sampled, 51.64% were infected and exhibited larger LC sizes, with females showing a greater mean size (x̄ = 20.06 mm). Fisher's test revealed no significant differences between sex and parasitic infection; however, significant differences were observed between LC and infection (r = 0.32, p < 0.001), especially in females (r = 0.31, p < 0.001). Two parasite species were identified: Profilicollis altmani (Acanthocephala), with a prevalence of 41.61%, and Proleptus sp. (Nematoda), with 4.74%. A survey conducted among the local population highlighted the current use of E. analoga in fishing and human consumption (e.g., omelet and ceviches), which poses an increased health risk given that more than 50% of the individuals were found to be infected.
期刊介绍:
Aquatic Ecology publishes timely, peer-reviewed original papers relating to the ecology of fresh, brackish, estuarine and marine environments. Papers on fundamental and applied novel research in both the field and the laboratory, including descriptive or experimental studies, will be included in the journal. Preference will be given to studies that address timely and current topics and are integrative and critical in approach. We discourage papers that describe presence and abundance of aquatic biota in local habitats as well as papers that are pure systematic.
The journal provides a forum for the aquatic ecologist - limnologist and oceanologist alike- to discuss ecological issues related to processes and structures at different integration levels from individuals to populations, to communities and entire ecosystems.
