Cytogenetic study of the genus Saguinus (Callithrichidae, Primates)

چکیده
Eight subspecies from the genus Saguinus (S. fuscicollis fuscicollis, S. fuscicollis weddelli, S. bicolor bicolor, S. bicolor martinsi, S. mystax mystax, S. imperator imperator, S. midas midas, and S. midas niger) were studied. Five of them (S. f. fuscicollis, S. f. weddelli, S. b. martinsi, S. m. mystax and S. i. imperator) had their karyotypes described for the first time. Conventional coloration, banding patterns G, C and NOR, and G/C sequential banding tecniques were used. All samples showed the same diploid number (2n = 46). The patterns of the G, C and NOR bands were very similar with little differences in the quantity and constitutive heterochromatin distribution of the autosomes. Constitutive heterochromatin was observed only in telomeric regions of some chromosomes of S. f. fuscicollis and S. f. weddelli. The X chromosome was the same in all subspecies, but chromosome Y differed in size and morphology. XX/XY chimerism was verified in all subspecies.

Dental microwear analysis is conducted on a community of platyrrhine primates from South America. This analysis focuses on the primate community of Cachoeira Porteira (Para, Brazil), in which seven sympatric species occur: Alouatta seniculus, Ateles paniscus, Cebus apella, Chiropotes satanas, Pithecia Pithecia, Saguinus midas, and Saimiri sciureus. Shearing quotients are also calculated for eac...

Chronic Plasmodium brasilianum infections in wild Peruvian tamarins
There is an increased interest in potential zoonotic malarias. To date, Plasmodium malariae that infects humans remains indistinguishable from Plasmodium brasilianum, which is widespread among New World primates. Distributed throughout tropical Central and South America, the Callitrichidae are small arboreal primates in which detection of natural Plasmodium infection has been extremely rare. Mo...
متن کاملEpstetn-barr Virus
Considerable efforts have been made to develop suitable animal models to study EBV infection and pathogenesis; however, such attempts have had little success, because Old World primates carry their own EBV-like virus and cross-reacting antibody (Kieff, 1996). New World primates do not carry EBV homologues, however, and at least five species appear to be infectable by EBV, i.e, the cotton-topped...
