Karyotype of an avian schistosome Trichobilharzia szidati (Digenea: Schistosomatidae)
International Journal for Parasitology, 1996Somatic 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, 1956of 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.

Argentophilic Papillae of Schistosomatium douthitti Cercariae (Trematoda: Schistosomatidae)
The Journal of Parasitology, 1979Argentophilic 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, 1986Heterobilharzia 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).

Hermaphroditic Female Schistosomatium douthitti (Trematoda: Schistosomatidae)
The Journal of Parasitology, 1951In 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 ...

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.

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 ...

Mitochondrial gene order change in Schistosoma (Platyhelminthes: Digenea: Schistosomatidae)
International Journal for Parasitology, 2012In 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, 1980The 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, 1981The 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 ...
