Conventional Giemsa-stained and C-banded chromosomes of seven strains of Schistosoma mansoni.
Karyotypes stained with conventional Giemsa and with a C-banding method were compared among 7 strains of Schistosoma mansoni: 2 from Puerto Rico and 1 each from St. Lucia, Brazil, Venezuela, Egypt, and Kenya. A few differences were noted in relative lengths and centromeric indexes, but overall karyotypes of all strains were similar, with 2n = 16. The W chromosome of the female of all strains had a relatively large heterochromatic block, distinguishing the female from the male karyotype.
