P.A.S. OLIVIER, S.M. DIPPENAAR, L.F. KHALIL & N.M . MOKGALONG. 2000. Observations on a lesser-known monogenean, Udonella myliobati, from a copepod parasite, Lepeophtheirus natalensis, parasitizing the spotted ragged-tooth shark, Carcharias taurus, from South African waters. Onderstepoort Journal of Veterinary Research, 67: 135-140 The phylogeny of the genus Udonella has been disputed for quite ...

We studied the systematics of 14 species of monogenean (Ancyrocephalidae) gill parasites from West African tilapiine hosts (Cichlidae) using both morphological and genetic data. With these tools, we were able to: (i) confirm the validity of the previously described morphological parasite species and of the genus Scutogyrus; (ii) propose that some stenoxenous species (i.e., parasite species with...

The Monogenea are an ideal group for investigations of the processes behind their past diversification and their present diversity for at least three reasons: they are diverse both in terms of morphology and numbers, they are generally host specific, and their phylogeny is well resolved, at least to the family level. The present investigation takes a broad look at monogenean diversity in order ...

Forty five specimens of the short beaked garfish Belone svetovidovi, a rare belonid species largely confused with the garfish Belone belone from Tunisian coast Sea were examined for metazoan parasite. Nine metazoan parasites species were identified: one monogenean (Axine sp.), 4 digeneans (Lecithostaphylus retroflexus, Tergestia acanthocephala, Aponurus laguncula and Condylocotyla pilodora meta...

It is widely accepted that disease interactions between cultured and wild fish occur repeatedly, although reported cases have mainly relied just on the observation of similar symptoms in affected populations. Whether there is an explicit pathogen transfer between fish stocks, or each develops its own pathogen population, has been insufficiently studied and rarely supported by molecular tools. I...

The starry smooth-hound Mustelus asterias is a near-threatened coastal shark in Europe, whose parasitofauna largely unknown. We studied metazoan parasites of 20 immature sharks (13 males and seven females) from the English Channel we examined their relationships with host condition use as bioindicators. All were parasitized by one to six taxa among twelve recorded whole sampling (one trematode,...

Helminth parasites secrete several types of biomolecules to ensure their entry and survival in hosts. The proteins secreted the extracellular environment participate pathogenesis anthelmintic immune responses. aim this work was identify functionally annotate excretory/secretory (ES) monogenean ectoparasite Rhabdosynochus viridisi through bioinformatic approaches. A total 1655 putative ES were i...

Monogenea is one of the most species-rich groups of parasitic flatworms worldwide, with many species described only recently, which is particularly true for African monogeneans. For example, Cichlidogyrus, a genus mostly occurring on African cichlids, comprises more than 100 nominal species. Twenty-two of these have been described from Lake Tanganyika, a famous biodiversity hotspot in which man...

The metazoan parasite fauna of Hippoglossina macrops (n = 123) from northern Chile (30 degrees S) is quantitatively described for the first time, and the role of host age and sex was evaluated. Twelve parasite species were recovered, including 5 ectoparasites (2 Monogenea, 2 Copepoda and 1 Piscicolidae) and 7 endoparasites (1 Digenea, 3 Cestoda, 2 Acanthocephala, and 1 Nematoda). The copepod Ho...
