“…This corresponds to our previous studies , Bayssade-Dufour et al 2006) which, however, focused only on selected bird schistosomes (nasal Trichobilharzia, Bilharziella and Dendritobilharzia). The present study is more complex, because it centres on a broader spectrum of birds and their schistosome parasites.…”

Abstract. In 2005, we dissected 102 wildfowl from the Czech Republic and 73 wildfowl from Poland including representatives of Anseriformes, Gruiformes and Gaviiformes. Schistosome infection was found in a total of 21 (29%) and 23 (23%) birds from Poland and the Czech Republic, respectively. All infected birds belonged to the order Anseriformes. The prevalences of nasal and visceral species were, respectively, 22% and 16% in Poland and 6% and 19% in the Czech Republic. Four species of schistosomes were found: Bilharziella polonica Kowalewski, 1895, Trichobilharzia regenti Horák, Kolářová et Dvořák, 1998, T. szidati Neuhaus, 1952, and an undetermined schistosome from the intestinal wall of Anas penelope L. The finding of T. szidati represents the first record of the parasite from natural final host since the species description.

“…Finding these parasites usually requires skilled helminthological examination. Recent studies showed that bird schistosomes are quite frequent in anatid birds of Western and Northern Europe (Simon-Martin and Simon-Vicente 1999, Skírnisson and Kolářová 2005, Bayssade-Dufour et al 2006, Kolářová et al 2006.…”

“…Yet the schistosome species found in a wide range of avian host orders (e.g., Bilharziella and Dendritobilharzia) ( Table 1) are not the ones recurrently responsible for outbreaks and are also species that are not genetically diverse compared to other species (69,125,126). Currently, D. pulverulenta might be the most widespread single species of avian schistosome, crossing both the Northern and Southern Hemispheres (117,125,127,128).…”

Avian Schistosomes and Outbreaks of Cercarial Dermatitis

et al. 2015

SUMMARY Cercarial dermatitis (swimmer's itch) is a condition caused by infective larvae (cercariae) of a species-rich group of mammalian and avian schistosomes. Over the last decade, it has been reported in areas that previously had few or no cases of dermatitis and is thus considered an emerging disease. It is obvious that avian schistosomes are responsible for the majority of reported dermatitis outbreaks around the world, and thus they are the primary focus of this review. Although they infect humans, they do not mature and usually die in the skin. Experimental infections of avian schistosomes in mice show that in previously exposed hosts, there is a strong skin immune reaction that kills the schistosome. However, penetration of larvae into naive mice can result in temporary migration from the skin. This is of particular interest because the worms are able to migrate to different organs, for example, the lungs in the case of visceral schistosomes and the central nervous system in the case of nasal schistosomes. The risk of such migration and accompanying disorders needs to be clarified for humans and animals of interest (e.g., dogs). Herein we compiled the most comprehensive review of the diversity, immunology, and epidemiology of avian schistosomes causing cercarial dermatitis.

“…These variations were not only observed for eggs isolated from different hosts (for example A. platyrhynchos and C. olor) but also among hosts belonging to the same species originating from different areas (for example the different size of eggs isolated from A. platyrhynchos from Iceland and France). This phenomenon can be explained by the appearance of variations depending on the final host, but also by environmental factors such as the seasons as shown by Bayssade-Dufour et al in 2006 for Bilharziella polonica and Dendritobilharzia pulverulenta.…”

Final hosts and variability of Trichobilharzia regenti under natural conditions

et al. 2010

View full text Add to dashboard Cite

In Europe, despite of intensive work on avian schistosomes in the past, only one representative of nasal schistosomes has been detected so far, Trichobilharzia regenti, a species that remained undescribed to the scientific community until 1998. Since then, however, T. regenti has gained a considerable attention, not only due to the induction of serious lesions concomitant with the migration of the schistosomulae through the central nervous system of their natural hosts (birds) but also due to their implication in cercarial dermatitis and their neurotrophic behaviour in mammals (mice, experimental) where the parasite migrate to the CNS. From 2001 to 2010, by a parasitic control of various potential final hosts (aquatic birds) living in natural condition in France and in Iceland, we detected T. regenti in six species: Anas platyrhynchos, Cygnus olor, Aythya fuligula, Aythya ferina, Mergus merganser and Anser anser. Although morphological features, mainly of eggs, showed some variations with the original description of the parasite, molecular analysis confirmed their membership to the T. regenti species. Nevertheless, specific molecular and morphological variations were especially observed for nasal parasite isolated from Anas clypeata. For this species, we discuss the possibility for this nasal schistosome to belong to a nasal Trichobilharzia species already described in Africa or even an undescribed nasal species.
