Journal ArticleDOI
Oral immunization and protection of raccoons (Procyon lotor) with a vaccinia-rabies glycoprotein recombinant virus vaccine.
Charles E. Rupprecht,Tadeusz J. Wiktor,David H. Johnston,Amir N. Hamir,Bernhard Dietzschold,William H. Wunner,Lawrence T. Glickman,Hilary Koprowski +7 more
TL;DR: This work demonstrates the feasibility of a recombinant virus vaccine containing the rabies glycoprotein gene for immunization of raccoons, and possibly other wildlife, to obtain long-term protection against rabies.
Journal ArticleDOI
Elimination of rabies from red foxes in eastern Ontario.
Charles D. MacInnes,Stephen M. Smith,Rowland R. Tinline,Neil R. Ayers,P. Bachmann,David Ball,Laurie A. Calder,Sarah J. Crosgrey,Carolyn Fielding,Peggy Hauschildt,Janet M. Honig,David H. Johnston,Kenneth F. Lawson,Christopher P. Nunan,Michael A. Pedde,Bruce A. Pond,Robert B. Stewart,Dennis R. Voigt +17 more
TL;DR: In 1995, the last bovine and companion animal cases were reported and in 1996 the last rabid skunk occurred, and only bat variants of rabies were present until 1999, when the raccoon variant entered from New York (USA).
Journal ArticleDOI
Efficacy of a Vaccinia-Rabies Glycoprotein Recombinant Virus Vaccine in Raccoons (Procyon lotor)
TL;DR: A vaccinia recombinant virus vaccine (V-RG) expressing the ERA (Evelyn-Rokitnicki-Abelseth) rabies virus glycoprotein was highly immunogenic for laboratory animals and raccoons by the intradermal, intramuscular, and oral routes.
Journal ArticleDOI
An Aerial Baiting System for the Distribution of Attenuated or Recombinant Rabies Vaccines for Foxes, Raccoons, and Skunks
David H. Johnston,Dennis R. Voigt,Charles D. MacInnes,P. Bachmann,Kenneth F. Lawson,Charles E. Rupprecht +5 more
TL;DR: The aerial distribution system is capable of economically reaching a high proportion of foxes, skunks, and raccoons over large areas and trials with attenuated ERA (Evelyn-Rokitnicki-Abelseth) vaccines are under way in Ontario.
Journal ArticleDOI
Wild carnivore acceptance of baits for delivery of liquid rabies vaccine
P. Bachmann,Richard N. Bramwell,Sarah J. Fraser,Douglas A. Gilmore,David H. Johnston,Kenneth F. Lawson,Charles D. MacInnes,Frank O. Matejka,Heather E. Miles,Michael A. Pedde,Dennis R. Voigt +10 more
TL;DR: The rapidity with which foxes picked up their first bait appeared more affected by unknown characteristics of years or study areas than by experimental variables, which has potential for field control of rabies, although higher acceptance will be desirable.
