The chromosomes of Biomphalaria tenagophila (Gastropoda--Basommatophora--Planorbidae).
The subfamilies Bulininae and Biomphalariinae are of medical importance being potential intermediate hosts of human and herbivore schistosomiasis. South America is inhabited by the subfamilie Biomphalariinae. Biomphalaria glabrata (=Australorbis glabratus) is the principal host of Schis tosoma mansoni in Brazil. In Argentina there are no cases of schistosomiasis as yet although Biomphalaria ten...

The specimens were collected in 15 localities in 12 municipalities of the southern region of the state of Rio Grande do Sul, Brazil. The following species were found and identified: Biomphalaria tenagophila guaibensis, Biomphalaria oligoza and Biomphalaria peregrina. ...
متن کاملPhylogenetic analysis of Biomphalaria tenagophila (Orbigny, 1835) (Mollusca: Gastropoda).
Mitochondrial DNA of Biomphalaria tenagophila, a mollusc intermediate host of Schistosoma mansoni in Brazil, was sequenced and characterised. The genome size found for B. tenagophila was 13,722 bp and contained 13 messenger RNAs, 22 transfer RNAs (tRNA) and two ribosomal RNAs (rRNA). In addition to sequencing, the mitochondrial DNA (mtDNA) genome organization of B. tenagophila was analysed base...
