“….Macroscopic examination revealed marked paleness of the infested fish gills with excessive mucous secretions forming claudy film of slime, the result which agree with that noticed by Paperna,I. (1991) for monogenean gill affection shape, vary in number (15)(16)(17)(18)(19)(20) and each measuring 0.06 -0.08 mm. Genital atrium is armed with 34-40 spines with curved tips.…”

“…From pathological point of view, the induced lesions depend on the type of monogenea and Some of them induce closely similar tissue changes [15,16]. Monogeneans feed mainly on the superficial layers of the skin and gills, this feeding activity is irritating and thus often causes skin cloudiness or focal reddening resulting from excess mucus production [17] Several blood-feeding polyopisthocotylean monogeneans have been shown to induce gill damage and mortality [18,19].…”

This investigation was realized between December 2012 to November 2013. A total of 400 Sea bream (Sparus aurata) were sampled with history of loss of appetite and sluggish movement with increased breathing frequency, were investigated in terms of monogenean parasites .The prevalence, seasonal dynamics, mean intensity as well as the histopathological influence of the detected monogeneans were estimated. The standard parasitological methods were used in the survey and yielded four monogenean species on the Sea bream gills: Furnestinia Echeneis (58.59% of invaded fish), Encotyllabe spari 32.81%, Sparicotyle chrysophrii 25.78% and Choriocotyle chrysophrii 17.19%. The total prevalence was 32% and the highest rate was recorded during summer. With the exception of Encotyllabe spari, the detected parasites are new records for the monogenean fauna of Egypt (new geographical record) and also Sea bream (Sparus aurata) is a new host record for the monogenean Choriocotyle chrysophrii. Histopathological examination revealed different pathological changes in the affected branchial tissue. The lesions were depended on the type of the detected monogenea. Necrosis of the gill lamellar epithelium, hyperplasia of mucous secreting cells and focal areas of denuded epithelium were the most common lesions noticed at the sites of parasites attachment.

Microcotyle visa n. sp. (Monogenea: Microcotylidae), a gill parasite of Pagrus caeruleostictus (Valenciennes) (Teleostei: Sparidae) off the Algerian coast, Western Mediterranean

et al. 2019

Parasite biodiversity of fish of the southern part of the Mediterranean sea is still incompletely explored. We describe here Microcotyle visa n. sp. from the gill filaments of the bluespotted seabream Pagrus caeruleostictus (Valenciennes) (Sparidae) collected off the Algerian coast. The identity of fish hosts was confirmed by barcoding. Microcotyle visa n. sp. is herein described and illustrated. Analysis of the cox1 gene of the monogeneans revealed minor intraspecific variation (1.4%), an order of magnitude lower than the distance between this species and other Microcotyle species (10-15 %). Microcotyle visa n. sp. is distinguished from Microcotyle erythrini van Beneden & Hesse, 1863, a congener infesting sparids, on the basis of morphological (size of clamps, number of testes) and molecular (cox1) differences. This is the fourth member of the genus known to parasitise a sparid host. A species of Paramicrocotyle sp. included in the molecular analysis was nested within a robust Microcotyle + Paramicrocotyle clade; in the absence of demonstrated molecular and morphological differences, we consider that Paramicrocotyle Caballero & Bravo-Hollis, 1972 is a junior synonym of Microcotyle van Beneden & Hesse, 1863 and transfer two species of Paramicrocotyle as Microcotyle danielcarrioni (Martinez & Barrantes, 1977) n. comb. and Microcotyle moyanoi (Villalba & Fernandes, 1986) n. comb.

Macroparasites of allis shad (Alosa alosa) and twaite shad (Alosa fallax) of the Western Iberian Peninsula Rivers: ecological, phylogenetic and zoonotic insights

et al. 2015

Samples of anadromous Alosa alosa (Clupeidae) (n = 163) and Alosa fallax (Clupeidae) (n = 223), caught in Western Iberian Peninsula Rivers from 2008 to 2013, were examined for buccal, branchial and internal macroparasites, which were identified using morphological and molecular methods. Alosa alosa were infected with Anisakis simplex s.s., Anisakis pegreffii, Hysterothylacium aduncum, Rhadinorhynchus pristis, Mazocraes alosae, Hemiurus appendiculatus, Ceratothoa italica and an unidentified ergasilid copepod. Ceratothoa italica represents a new host record for A. alosa. Alosa fallax were infected with A. simplex s.s., A. pegreffii, H. aduncum, H. appendiculatus, Clavellisa emarginata and an unidentified cymothoid isopod. This is the first report of C. italica, C. emarginata and M. alosae in the Iberian Peninsula. The phylogenetic positions of M. alosae, H. appendiculatus and C. emarginata were assessed using 18S and 28S ribosomal RNA (rRNA); our contributions provide a better understanding of the phylogenetic relationships within their groups. Qualitative and quantitative differences in the parasite faunas of these two shad species are consistent with different feeding strategies. The results provide information about host migration behaviour and transmission pathways through diet during the marine trophic phase of the shad's life cycle and their roles as paratenic or final hosts and transporters of parasites between seawater and freshwater environments. The zoonotic parasites A. simplex s.s. and A. pegreffii pose a risk for consumers or riverine mammals (e.g. European otter). The use of parasites as biological tags for shad stocks in Western Iberian Rivers could be a useful approach in multidisciplinary studies concerning fish stock delimitation and characterization.
