Abstract

The world distribution of oriental culture and the common use of fish which is not cooked manifested problems related to parasites. There is a great incidence of Ascocotyle sp. parasites in mullet fishes, which are part of human culinary spread all over world. The aim of the present study is to estimate the presence of trematode Heterophyidae metacercariae among mullet fishes commercialized at Iguape city Sao Paulo, Brazil. Ascocotyle sp. metacercarie (Digenea: Heterophyidae) were observed and analyzed in viscera and muscles of 60 mullets Mugil liza and 60 mullets Mugil curema (Osteichthyes: Mugilidae) purchased in the fish market of the Iguape city. The extraction of metacercariae of Ascocotyle sp. from viscera and muscles was performed by homogenization in homemade processor. All mullets samples were infected. M. liza and M. curema marketed in city constitute in a potential risk to the population, because of high prevalence of infection (100%) and large numbers of metacercarie in their tissues (up to 939 to M. liza and 92 to M. curema).

在巴西圣保罗IGUAPE市的商业鱼类中收集的MUGIL LIZA和MUGIL CUREMA(骨鱼目:MUGILIDAE)组织中的METACERCARIA DE ASCOCOTYLE SP. (DIGENEA: HETEROPHYIDAE)

东方文化的世界分布和不煮鱼的普遍使用表明了与寄生虫有关的问题。乌鱼是世界各地人类食用的一部分，其子囊纲寄生虫在乌鱼中发病率很高。本研究的目的是估计在巴西圣保罗市伊瓜普市销售的鲻鱼中吸虫异泡囊蚴的存在。对在伊瓜普市鱼市购买的60条乌鱼(Mugil liza)和60条古乌鱼(Mugil curema)的内脏和肌肉进行了子囊类囊蚴(dienea:异鳍鱼科)的观察和分析。在自制的加工机上均质提取子囊纲动物内脏和肌肉中的囊蚴。所有鲻鱼样本均被感染。由于感染的高流行率(100%)和组织中大量的包囊蚴(liza和currema分别高达939和92)，在城市中销售的M. liza和M. curema对人群构成潜在风险。
