RÉSUMÉ. Une étude comparative des isoenzymes est effectuée sur les adultes de trois espèces du genre Echinostoma (E. caproni, E. togoensis, E. sp.). Parmi les 23 enzymes recherchées par électro-phorèse en gel d'amidon, la Pgm et la Pgi sont caractérisées par des zymogrammes différents chez les trois espèces. L'isoélectrofocalisation en gel d'agarose et de polyacrylamide précise la structure génétique de chaque enzyme : la Pgm est codée par trois locus, la Pgi par un seul. Le polymor phisme de la Pgm permet d'envisager l'étude d'autres souches expérimentales ou naturelles. (Voltz et coll., 1985). Une espèce isolée du Cameroun, E. sp., paraît très proche des deux précédentes tant par la morphologie des larves et des adultes que par le cycle expérimental (Bertram, 1983). L'analyse comparative des protéines et des isoenzymes des trois espèces est entreprise dans le but de préciser les caractères génétiques de chacune et d'aborder la chimiotaxonomie du genre Echinostoma dont la systématique demeure controversée (Kanev, 1985). L'électrophorèse en gel d'amidon épais permet

Although Patagifer is a rather small genus, the problematical description of Dietz (1910), in which a high variation was attributed to the type-species, P. bilobus, plus the long history of inadequate descriptions and/or poor differential diagnoses of newly established taxa, have resulted in a complicated synonymy, especially with regard to the species described from Asian material.…”

Patagifer Dietz, 1909 is revised and a key to the species is presented. P. oweni n. sp. is described from Threskiornis molucca (Cuvier) in the Western Province of Papua New Guinea and distinguished from the related P. chandrapuri Srivastava, 1952 by: the shape of the pair of large angle spines (cudgel-shaped vs sub-rectangular); pointed (vs rod-shaped) marginal spines; a smaller body and internal organs; more anteriorly located testes; and larger eggs. The new species differs from P. brygooi Richard, 1964 in its larger body, head collar, suckers, pharynx and eggs, longer oesophagus and testes, the latter being also more elongate and more anteriorly located, and a different number of collar spines (61-62 vs 59). P. bilobus (Rudolphi, 1819) (the type-species), P. parvispinosus Yamaguti, 1933, P. chandrapuri and P. vioscai Lumsden, 1962 are redescribed on the basis of museum and newly collected material. The variations in the number and size of the collar spines and other metrical characters of P. bilobus are studied in two different host species from Europe, Plegadis falcinellus and Platalea leucorodia. Other species considered valid are: Patagifer consimilis Dietz, 1909, P. acuminatus Johnston, 1917, P. fraternus Johnston, 1917, P. wesleyi Verma, 1936, P. brygooi and P. toki Onda, Imai & Ishii, 1983. P. plegadisi Sakla, Monib & Mandour, 1988 and P. simarai Nigam, 1944 are considered synonyms of P. bilobus, and P. sarai Saksena, 1957 is placed in synonymy with P. chandrapuri. Forms considered dubious are: P. bilobus of Machida et al. (Jpn J Parasitol 15:339, 1966) and Machida (Bull Natl Sci Mus Tokyo 11:157-160, 1968), P. simerai [sic] of Mehra (The fauna of India and adjacent countries. Platyhelminthes, 1980), P. skrjabini Hilmy, 1949 sp. inq. and P. srivastavai Peter, 1954 sp. inq. Lists of the records and hosts of the 11 valid species are included.

“…These studies covered worldwide species and were based on morphological, biological and ecological features. These authors re-examined and redescribed three species and concluded that only five species may be considered valid in the "revolutum" group: E. revolutum, E. echinatum (Zeder, 1803), E. trivolvis (Cort, 1914), E. jurini (Skvorozov, 1924) and E. caproni Richard, 1964. The conclussions of these authors have been widely accepted and, for a time have constituted the basis of diagnosis in the "revolutum" group.…”

Echinostomatidae (Trematoda) is the largest family within the class Trematoda. Members of this family have been studied for many years in relation to their utility as basic research models in biodiversity and systematics and also as experimental models in parasitology since they offer many advantages. Echinostomes have contributed significantly to numerous developments in many areas studied by parasitologists and experimental biologists. In this review, we examine the history of the echinostomebased studies from the beginnings to the present. For this purpose, we have divided the history of echinostomes into four periods (i.e. 18 th and 19 th centuries, first half of the 20 th century, second half of the 20 th century and the late 20 th and 21 th century) according to the types of studies performed in each of them. Moreover, we also briefly review the history of echinostome infections in humans.
