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).

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 ...

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.

A Review of the Genus Dendritobilharzia Skrjabin and Zakharow 1920 (Trematoda: Schistosomatidae)
The Journal of Parasitology, 1980An historical review, the geographical distribution, and a list of known hosts for the genus Dendritobilharzia Skrjabin and Zakharow 1920 are presented. Nine new host records are included. Dendritobilharzia loossi Skrjabin 1924 and D. anatinarum Cheatum 1941 are considered synonyms of D. pulverulenta (Braun 1901) Skrjabin 1924, and D.

Uniparental Miracidia of Schistosomatium douthitti and their Progeny (Tremaoda, Schistosomatidae)
American Midland Naturalist, 1952In 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.

STUDIES ON CERCARIAL DERMATITIS AND THE TREMATODE FAMILY SCHISTOSOMATIDAE IN MANITOBA
Canadian Journal of Research, 1940A biological investigation of cercarial dermatitis in Manitoba has revealed that three species of apharyngeal brevifurcate cercariae are responsible for the disease. An ecological study of the organisms and their molluscan hosts has been carried out, and descriptions of the general types of habitats are given in addition to the distribution of the ...
