Forty-two chromosomes were counted from expanded cultured cells of four Celebes apes, Cynopithecus niger. Mitotic cells from three Indian langurs, Presbytis entellus, contained 44 chromosomes. These counts support cytogenetically the taxonomical classification of these animals according to Simpson.
Angora, New Zealand, and Dutch-belted rabbits were tested for their susceptibility to graded doses of
Herpesvirus hominis
type 2 administered by vaginal instillation, intracorneal injection, and scarification of the cornea. Central nervous system involvement and death occurred after infection by the various routes employed. Prior immunization of Dutch-belted and New Zealand rabbits with viable
Mycobacterium bovis
(BCG) cells injected intravenously provided protection against subsequent infections with type 2 virus.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
