Chromosomal evolution in Callithrix emiliae.

We studied the karyotype of specimens of Callithrix emiliae (Callithricidae, Primates) from Rondonia, Brazil. Comparison with the karyotype of Callithrix jacchus showed that, even though these two species show many karyotypic similarities, they differ by a Robertsonian translocation, a paracentric inversion and large-scale addition of heterochromatin. The C. emiliae species appears to be in an active phase of chromosome evolution by the addition of constitutive heterochromatin.

The association of blood groups, ABH secretion, haptoglobins and hemoglobins with filariasis.

Results on 605 patients and 597 controls carefully matched in relation to sex, age, marital status and profession are reported. A higher frequency of nonsecretors, as well as an excess of B and lack of A2 were observed among the filarial patients. Since these differences do not occur in other series, however, their significance is doubtful.
