Unlike other long-term studies of Diplostomum spp. metacercariae in fish eyes, this study investigated accumulation of the parasites in the eyes of very young roach for 3 consecutive years. Fish were caught by electro-fishing in the summers of 1990, 1991 and 1992 and the numbers of parasites located in the hosts eyes were recorded.

Parasite communities in freshwater fish vary annually and seasonally and can be influenced by the length, age, sex and phylogeny of hosts, and by associations among parasite species. We assessed the influence of these factors in species of Diplostomum in the eyes of 828 fish in 20 different species collected in a single lake in early summer or autumn ...

Experiments have shown thai infection by low intensities of the eye fluke affects the vision of three‐spined stickleback when selecting prey, and also shortens the reactive distance to the prey. The results have consequences for the fitness of the individual, and also for the study of prey selection.

In this study, sequences from the barcode region of cytochrome c oxidase I (COI) were used to distinguish Diplostomum spp. in a sample of 497 metacercariae collected from diverse fishes of the St. Lawrence River, Canada and findings were corroborated with internal transcribed spacer (ITS) regions of rDNA. Twelve species were detected based on sequences

Abstract. A histopathological study was carried out on rainbow trout suffering from acute and chronic diplostomiasis. Clinical signs were few in acutely infected fish but in chronic cases fish were blind, exophthalmic and emaciated. Acute infections resulted in subcapsular cataract formation with varying capsular change.

Metacercariae of the genus Diplostomum dwelling in the retina of perch Perca fluviatilis and the lens of roach Rutilus rutilus were identified on the basis of adults obtained by feeding various piscivorous birds of the families Laridae, Anatidae and Phasianidae with metacercariae on an experimental basis. Both morphological studies of the metacercariae

Two distinct site‐specific populations of Diploslomum spp., occurring concurrently in the lens and retina of naturally infected rainbow trout, were different morphologically. They represent separate populations epidemiologically. The lens and retina metacercariae did not differ immunologically when tested by an enzyme‐linked immunosorbent assay against

Survival of two trematode parasites (Diplostomum spp.) in mammalian eyes and associated pathology.
Canadian journal of ophthalmology. Journal canadien d'ophtalmologie, 1976Cercariae of Diplostomum spathaceum dropped onto the eyes of small unanaesthetized rabbits penetrated through the cornea, crossed the anterior chamber, and entered the lens. After 2-3 weeks they died and became semi-permanent amorphous cataracts. Cercariae remaining in the cornea became the centres of stromal nebulae 0.1-0.2 mm across which remained ...

Based on the morphology of adults recovered from experimental infection of gulls, the metacercariae from the eyes of lake whitefish were identified as Diplostomum spathaceum indistinctum and Diplostomum baeri bucculentum. The two species inhabit different sites in both fish and bird hosts:D. s. indistinctum in the lens and D. b.

Abstract Metacercariae of Diplostomum spp. are widespread fish parasites. In this study we obtained the first data on infection of Bullhead Cottus koshewnikowi with these larvae in five rivers of northern Europe (Finland and Russia) using molecular and morphological description. Three Diplostomum spp.
