Parasitized gonads showed digenean
trematode infection directly inside of follicles, but their connective tissue, in both females and males, showed the same organization relative to nonparasitized gonads; histological changes, however, were evident within parasitized follicles, including the displacement of oocytes and sperm and a heavy hemocytic infiltration process.
Results: Two digenean
species were recorded: Prosorhynchoides gracilescens (Bucephalidae), which is commonly found in L.
Some helminth parasites of marine fishes and cephalopods of South Africa: Aspidogastrea and the digenean
families Bucephalidae, Haplosplanchnidae, Mesometridae and Fellodistomidae.
nuchalis suggests that this fish is a secondary intermediate host that consumes mollusks, which are primary intermediate hosts for this digenean
that in general have as definitive hosts the fish eating-birds (Marcogliese et al.
To identify the trematode by real-time PCR, a new set of primers was designed in our laboratory on the basis of conserved ITS2 sequences of the digenean
trematodes, including P.

The main biological disease-causing agents in marine bivalves are viruses bacteria fungi protists digenean

Paramphistomosis (or amphistomosis) is a disease caused by digenean

Information concerning digenean
parasites of freshwater fish in southern Africa and parts of Africa is scant and far from complete.
Effect of the digenean
parasite Proterometra mactrostoma on host morphology in the freshwater snail Elimia livescens.
The recovered helminths were identified as 1 digenean
trematode species, Neodiplostomum reflexum; 2 species of nematodes, Synhimantus species, and larvae of Porrocaecum species; and a single species of Acanthocephala, Centrorhynchus species.
