The chromosomes of Rodentolepis nana (Siebold, 1852) Spasskii, 1954 obtained from naturally infected mice conventionally maintained in a Braziuan laboratory animal house.
The karyotype of Rodentolepis nana obtained from mice in Rio de Janeiro, Brazil, was described. The diploid chromosome number obtained by the division of embryonic cells was 2n = 12. The first and the third pairs presented subterminal centromeres and the other pairs were all acrocentric. The studied species differed in chromosome morphology when compared to previous description by Mutafova and Gergova (1994) in Bulgaria, suggesting an intraspecific variation.
