Two new genera and species of avian schistosomes from Argentina with proposed recommendations and discussion of the polyphyletic genus Gigantobilharzia (Trematoda, Schistosomatidae)

Parasitology, 2022
Abstract Gigantobilharzia Odhner, 1910 (Schistosomatidae) includes species that parasitize several orders of birds and families of gastropods from both freshwater and marine environments worldwide.

Parthenogenesis in Schistosomatidae

Parasitology Today, 1995
Among which species, in what situations and how, does parthenogenesis occur in the biology of reproduction of schistosomes? Here, José Jourdane, Daniéle Imbert-Establet and Louis Albert Tchuem Tchuenté review the literature on parthenogenesis in schistosomes, and debate the evolutionary aspects of this type of reproduction.

Hermaphroditic Female Schistosomatium douthitti (Trematoda: Schistosomatidae)

Journal of Parasitology, 1951
In trematodes of the family Schistosomatidae it has long been considered that there is complete separation of sexes, in contrast to the hermaphroditic condition occurring in other families of flukes. However, recent reports on hermaphroditic tendencies in males of the genus Schistosoma (Vogel, 1947; Short, 1948a; Gonnert, 1949; and Lagrange and ...

A new schistosome (Digenea: Schistosomatidae) from the nasal tissue of South America black-necked swans, Cygnus melancoryphus (Anatidae) and the endemic pulmonate snail Chilina gibbosa.

Zootaxa, 2021
To date, 9 species of Schistosomatidae have been found parasitizing the nasal tissues of mammal and bird hosts in the Eastern Hemisphere, 5 species in Rwanda (Africa), 2 in Australia (Oceania) and 2 in Eurasia.

Cultivation in vitro of Schistosomatium douthitti (Trematoda: Schistosomatidae)

International Journal for Parasitology, 1982
Abstract Cultivation in vitro of Schistosomatium douthitti (Trematoda : Schistosomatidae). International Journal for Parasitology12: 541–545. We grew S. douthitti in vitro from the cercaria to pairing ovigerous adults, using methods and media previously reported for cultivation of Schistosoma mansoni. Growth of S.

A new species of Trichobilharzia (Digenea: Schistosomatidae) from Mareca sibilatrix (Aves: Anatidae), an endemic South American duck

Journal of Helminthology
Avian schistosomatids are blood flukes parasitizing a wide spectrum of aquatic birds. However, its research in the Neotropics is ongoing with several putative new taxa pending description.

Uniparental Miracidia of Schistosomatium douthitti and their Progeny (Tremaoda, Schistosomatidae)

American Midland Naturalist, 1952
In a paper to be published elsewhere I show that females of Schistosomatium douthitti mature sexually in definitive hosts (mice) in the absence of males; that these females lay eggs and that many such eggs develop parthenogenetically, giving rise to uniparental miracidia. It is pointed out that in unisexual infections with female S.

Karyotype of an avian schistosome Trichobilharzia szidati (Digenea: Schistosomatidae)

International Journal for Parasitology, 1996
Somatic chromosomes of Trichobilharzia szidati Neuhaus, 1952 are described from larval stages dissected from snails, air-dried on slides and stained with Giemsa and C-banding technique, used for the first time in Trichobilharzia sp. The karyotype consisted of 7 autosomal pairs and 1 pair of sex chromosomes, ZZ in the male and ZW in the female, where Z ...

Encephalitis in a Swan Due to Dendritobilharzia sp. (Trematoda; Schistosomatidae)

The Journal of Parasitology, 1956
of the encephalitic symptoms, a virus disease was suspected, and chick embryos were inoculated with brain tissue. The brain, duodenum, liver, pancreas, gizzard and proventriculus were fixed in Zenker's fluid, sectioned and stained with hematoxylin and eosin. A segment of small intestine was placed in the refrigerator.
