Tissue sections from 237 nine-banded armadillos (Dasypus novemcinctus) from 51 central Texas counties were examined microscopically for acid-fast bacilli and/or lesions of leprosy. Neither were found. A review of the literature relative to the incidence of leprosy from armadillos in Texas indicates that residents of counties along the Texas Gulf Coast may be at risk of contracting leprosy by handling infected armadillos or their tissues.
Samples from 77 nine-banded armadillos (Dasypus novemcinctus) inhabiting a 16.7 km portion of the East Atchafalaya River Levee, Point Coupee Parish, Louisiana, were serologically tested and/or histopathologically examined for evidence of naturally acquired leprosy. Five of 67 (7.5%) armadillos tested sero-positive with ELISA test for IGM class antibodies to the phenolic-glycolipid-1 antigen of Mycobacterium leprae. One of 74 (1.3%) was histopathologically positive as determined by presence of acid-fast bacteria in nerves.
This chapter addresses the origin of higher primates, this reduces to two more specific questions: What were the most primitive higher primates like?; and what were possible precursors at an earlier stage like, and to which of these are primitive anthropoids most similar? In other words the general problem of the origin of higher primates focuses on the question of whether Oligocene Simiiformes more closely resemble Eocene Omomyidae or Eocene Adapidae. Fossil primates, mammalian faunas, and paleogeography have a direct bearing on the origin of South American monkeys. The dental formula of omomyids and adapids is variable and by itself does not suggest special affinity of either group to early simiiform primates. On the other hand, virtually all other dental characteristics distinguish Adapidae and Simiiformes from Omomyidae. The structure of the ectotympanic in Omomyidae is tubular as it is in Tarsius.
