<em>Eustrongylides</em> spp. is considered a freshwater fish zoonotic nematode. In the present study, the prevalence of <em>Eustrongylides</em> spp. in six edible fish (European perch - <em>Perca fluviatilis</em>, goldfish - <em>Carassius auratus</em>, largemouth black bass - <em>Micropterus salmoides</em>, tench- <em>Tinca tinca</em>, carp - <em>Cyprinus carpio</em> and sand smelt - Atherina boyeri) of Trasimeno lake was surveyed. The investigations were conducted from October 2014 to September 2015 and 384 specimens per species for each season were caught in Trasimeno lake and examined for the presence of larvae in the abdominal cavity and muscle. The presence of nematodes in the abdominal cavity and musculature was revealed in three fish species. The prevalence of Eustrongylides spp. infection was 6.84, 1.89 and 0.13% in perch, largemouth black bass and sand smelt, respectively. The number of parasites per fish was only one in largemouth black bass and sand smelt and ranged from one up to three in perch. This study states that the European perch, largemouth black bass and sand smelt of Trasimeno lake are infected with zoonotic parasites; therefore, food business operators have to take appropriate measures to guarantee the health of consumers.

Reported Study

AbstractIn July 2005 a Koi carp from a private pond in Bavaria was investigated. The aim of the presently reported study was to determine the composition of the monogenean fauna of Koi carp, Cyprinus carpio var. koi and to observe the development of Dactylogyrus extensus, under natural conditions, on the fish gills. A total of three species were recovered, namely: Dactylogyrus extensus Müller et Van Cleave, 1932, Dactylogyrus minutus Kulwieć, 1927, and Gyrodactylus cyprini Diarova, 1964. The dominant species was D. extensus, while the remaining monogeneans were not abundant. Six developmental stages of D. extensus were defined and they were compared with those previously observed by Prost (1963), under experimental conditions. The differences observed in size of the sclerotised structures of the haptor and the copulatory apparatus were discussed.
