Description and surface topography of the cercaria of Austrobilharzia sp. (Digenea: Schistosomatidae)

Parasitology International, 2004
The cercaria of Austrobilharzia sp. from the marine prosobranch gastropod Planaxis sulcatus in Kuwait Bay is described. The surface microtopography and pattern of the tegumentary sensory receptors are examined using scanning electron microscopy. The general microtopography of the surface of the cercaria is similar to that previously observed in ...

Argentophilic Papillae of Schistosomatium douthitti Cercariae (Trematoda: Schistosomatidae)

The Journal of Parasitology, 1979
Argentophilic papillae of cercariae of Schistosomatium douthitti were studied by light microscopy. The basic number of body papillae was 56, excluding 20 at the anterior tip. The average number of tail papillae was 18. Average locations and spatial ranges of body papillae indicate a rather constant pattern.

Chromosomes of Heterobilharzia americana (Digenea: Schistosomatidae) from Texas

The Journal of Parasitology, 1986
Heterobilharzia americana is 1 of 2 known species of mammalian schistosomes indigenous to North America and is the only species in its genus. Reported vertebrate hosts include dogs, raccoons, nutria, and other wild animals (Goff and Ronald, 1981, American Journal of Veterinary Research 42: 1775-1777).

Maintenance of Schistosomatium douthitti (Cort, 1914) in the Laboratory (Trematoda: Schistosomatidae)

The Journal of Parasitology, 1954
In the United States, in addition to several avian schistosomes and Heterobilharzia americana found in the raccoon and lynx (Price, 1943), we have Schistosomatium douthitti occurring naturally in muskrats and field mice. S. douthitti is readily maintained in the laboratory and its life cycle is essentially the same as the species parasitizing man.

Mitochondrial gene order change in Schistosoma (Platyhelminthes: Digenea: Schistosomatidae)

International Journal for Parasitology, 2012
In the flatworm genus Schistosoma, species of which include parasites of biomedical and veterinary importance, mitochondrial gene order is radically different in some species. A PCR-based survey of 19 schistosomatid spp. established which of 14 Schistosoma spp. have the ancestral (plesiomorphic) or derived gene order condition.

CHROMOSOME ANALYSIS OF SCHISTOSOMA RODHAINI (TREMATODA: SCHISTOSOMATIDAE)

Canadian Journal of Genetics and Cytology, 1980
The chromosome number of Schistosoma rodhaini Brumpt is 2n = 16, with apparent sexual dimorphism quantifiable in chromosome pair no. 2. A method for dissociating host tissue coupled with hypotonic treatment yields permanent mitotic chromosome spreads with very defined centromere regions. The karyotype of S.

Karyotype evolution and sex chromosome differentiation in schistosomes (Trematoda, Schistosomatidae)

Chromosoma, 1981
The morphology of C-banded metaphase chromosomes has been studied in two hermaphroditic and ten gonochoristic digenetic trematodes (schistosomes). Comparison of numbers and morphology of chromosomes indicates that the karyotype of primitive trematodes probably was composed of 10 (or 11) pairs of telocentric or subtelocentric chromosomes, and reduction ...

Evolutionary Relationships among the Schistosomatidae (Platyhelminthes: Digenea) and an Asian Origin for Schistosoma

The Journal of Parasitology, 2000
Schistosome blood flukes parasitize birds, mammals, and crocodilians and are responsible for causing one of the great neglected diseases of humanity, schistosomiasis. A phylogenetic study of 10 schistosome genera using approximately 1,100 bases of the large subunit of the nuclear ribosomal gene complex revealed 2 major clades.
