To the Editor: The digenean
trematode Alaria alata is considered an emerging zoonotic parasite in Europe because of increased findings in wild boars during Trichinella inspection.
The results showed the presence of rickettsiales-like organisms (RLO) in the epithelium of the digestive gland, ciliates, and unidentified coccidia in gills, a meront-like cell in one digestive gland, digenean
trematode sporocysts in gonads, metacercariae embedded in the foot, and turbellarians in gills.
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.
The nine studies cover catalytic activity in transcripts from Schistosoma non-autonomous retro-transposons, mobile genetic elements of malaria vectors and other mosquitoes, retro-transposons in the genomes of the digenean
parasitic trematodes Clonochis sinensis and Paragonimus westermani, endogenous retro-transposon sequences of the Schistosoma mansoni intermediate snail host Biomphalaria glabrata, the transposon-mediated transgenis of mosquitoes, Schistosome long terminal repeat retro-transposons colonizing Schistosome genomes, Schistosome DNA transposons, and mobile genetic elements resident in hookworm genomes.
Phonology of recruitment and infection patterns of Ascocotyle pachycystis, a digenean
parasite in the sheepshead minnow, Cyprinidon variegatus.
Cercariae were extracted for DNA and PCR's were performed for detection of Neorickettsia (16S rRNA gene), and for identification of digenean
harteri (655 mm SVL female, CVC 880708-6) collected from the Somervell County site on 8 July 1988 was found to be infected in its mouth with four specimens of the digenean
trematode Ochetosoma aniarum.
Among influences on digenean
infection parameters in fish are the distributions and abundances of molluscan intermediate hosts, where the parasites perform one or more generations of asexual reproduction.

This manuscript reports and illustrates a digenean
species of subfamily Diplostominae and two species and one genus of nematodes of superfamily Oxyuridea found in S.
