Synaptonemal complexes and XY behavior in two species of Argentinian armadillos: Chaetophractus villosus and Dasypus hybridus (Xenarthra, Dasypodidae).
Spermatocytes from the two armadillo species, C. villosus and D. hybridus were studied in microspreads for synaptonemal complexes (SCs) and in thin sections for electron microscopy (EM). The complete SC karyotype generally agrees with previous reports on mitotic chromosomes, except for the sex chromosomes. The X chromosome is submetacentric in both species and the Y is the shortest one in C. vi...
متن کاملRecords of Nine-Banded Armadillos, Dasypus novemcinctus, in Illinois
The nine-banded armadillo, Dasypus novemcinctus, has been expanding its range in the United State since the mid-1800s. There had been sporadic reports of this species in Illinois prior to 1990. I conducted a mail survey in 2003 of individuals knowledgeable about the fauna of southern Illinois to investigate the possible expansion of the armadillo into the state. I also sent questionnaires to an...
متن کاملThe fetomaternal interface in the placenta of three species of armadillos (Eutheria, Xenarthra, Dasypodidae)
BACKGROUND Placental characters vary among Xenarthra, one of four supraordinal clades of Eutheria. Armadillos are known for villous, haemochorial placentas similar to humans. Only the nine-banded armadillo has been well studied so far. METHODS Placentas of three species of armadillos were investigated by means of histology, immunohistochemistry including proliferation marker, and transmission...
متن کاملPatterns of Mycobacterium Leprae Infection in Wild Nine-banded Armadillos (dasypus Novemcinctus) in Mississippi, Usa.
The nine-banded armadillo ( Dasypus novemcinctus ) is the only known nonhuman reservoir of Mycobacterium leprae , the causative agent of Hansen's disease or leprosy. We conducted a 6-yr study on a wild population of armadillos in western Mississippi that was exposed to M. leprae to evaluate the importance of demographic and spatial risk factors on individual antibody status. We found that spati...
