Etude des vers parasites des Amphibiens anoures de la région de Bordeaux

Abstract

Nous allons seulement opposer les principaux caractères distinc tifs et grouper les espèces trouvées en un tableau dichotomique simplifié.Identifier une espèce, c'est la comparer en tous points à celle qui est classiquement décrite à la suite d'un travail original. Cette iden tification à la description originale est faite pour chaque ver. Elle nous conduit, pour certains spécimens, à la mise en évidence de Ann. de P a r a s i t o l o g i e , t. X X IX , n° 5-6. -1954.

Common occurrence of Cryptosporidium hominis in asymptomatic and symptomatic calves in France

“…The presence of Cryptosporidium spp. oocysts was microscopically determined by the same experienced clinical parasitologists using Bailenger type feces concentration method [ 28 ] and Heine staining [ 29 ]. The presence of other intestinal parasites ( Giardia , Strongyloides , and coccidia) detected in some of the calves using various methodologies was not considered in the present study.…”

Helminths of the Eurasian marsh frog, Pelophylax ridibundus (Pallas, 1771) (Anura: Ranidae), from the Shiraz region, southwestern Iran

“…Haematoloechus similis (Looss, 1899) (Digenea: Haematoloechi dae) has been recorded in P. ridibundus in the North East of Iran (Combes & Knoepffler, 1972) and in several species of Pelophylax and Rana in Europe: P. kl. esculentus Linnaeus, 1758 (Bailenger & Chanseau 1954; Bjelic–Cabrilo et al 2009; Chikhlaev et al 2009; Looss, 1899; Odening, 1960; Prokopic & Krivanec, 1974); P. ridibundus (Odening, 1960; Romanova & Matveeva 2010; Saeed et al, 2007) , Rana arvalis Nilsson, 1842 (Odening 1960; Tkach et al 2000); R. temporaria Linnaeus, 1758 (Chikhlyaev & Ruchin 2014; Odening, 1960); Rana sp. (Travassos & Darriba 1930).…”

Hidden in plain sight: novel molecular data reveal unexpected genetic diversity among paramphistome parasites (Digenea: Paramphistomoidea) of European water frogs

“…The first was identified as Opisthodiscus diplodiscoides , with average to low prevalence per host population and low intensity of infection per examined host individual, and the second was Diplodiscus subclavatus , with comparatively higher prevalence and infection intensity. Previously, representatives of the genus Opisthodiscus have been found relatively rarely in European amphibians, in comparison to those of the genus Diplodiscus (Bailenger and Chanseau, 1954 ; Vojtková et al ., 1963 ; Combes and Gerbaux, 1970 ; Combes and Sarrouy, 1971 ; Grabda-Kazubska, 1980 ; Martínez-Fernández et al ., 1988 ; Vojtková and Roca, 1994 ; Andreas, 2007 ; Navarro and Lluch, 2006 ). In Western Europe, the genus Opisthodiscus is represented by O. nigrivasis parasitizing endemic Iberian P. perezi (López-Seoane, 1885) and widely distributed P. esculentus (Combes and Gerbaux, 1970 ; Combes and Sarrouy, 1971 ; Martínez-Fernández et al ., 1988 ).…”

“…So far, only 1 Diplodiscidae species is reported from European water frogs. Diplodiscus subclavatus (Pallas, 1760) is a common species which parasitizes the rectum of amphibians all across Europe, with a distribution range from the Iberian Peninsula in the west up to the Ukraine and Turkey in the East (e.g., Bailenger and Chanseau, 1954 ; Gomez, 1987 ; Vojtková and Roca, 1994 ; Navarro and Lluch, 2006 ; Bjelić-Čabrilo et al ., 2009 ; Popiołek et al ., 2011 ; Düşen and Öz, 2013 ; Karakaş, 2015 ; Herczeg et al ., 2016 ; Kuzmin et al ., 2020 ; Čeirāns et al ., 2021 ). The family Cladorchiidae is represented by 2 species parasitizing water frogs in Europe – Opisthodiscus diplodiscoides Cohn, 1904 and O. nigrivasis Mehély, 1929 .…”

“…The family Cladorchiidae is represented by 2 species parasitizing water frogs in Europe – Opisthodiscus diplodiscoides Cohn, 1904 and O. nigrivasis Mehély, 1929 . Species of this genus are less prevalent and are reported from France (Dollfus, 1951 ; Bailenger and Chanseau, 1954 ; Combes et al ., 1973 ), Germany (Andreas, 2007 ), Slovakia (Kopřiva, 1957 ; Vojtková, 1974 ), Poland (Grabda-Kazubska, 1980 ), Spain (Combes and Gerbaux, 1970 ; Combes and Sarrouy, 1971 ; Martínez-Fernández et al ., 1988 ) and Hungary (Mehély, 1929 ; Sey, 1991 ). The 2 Opisthodiscus species have often been considered a single taxon, since their morphological differentiation is not fully clear (Odening, 1959 ), and, therefore, their hosts and expected distribution have to be viewed with caution.…”
