| Abstract: | Striped skunks (Mephitis mephitis) were exposed to challenge virus standard rabies virus by feeding infected mouse brain in suspension or as intact brain free choice, by forced feeding of suspension, and by intranasal, intratracheal and intraintestinal instillation of suspension. All of five skunks exposed intranasally, two of five exposed intratracheally and two of ten exposed by forced feeding developed rabies. None of the skunks exposed to challenge virus standard virus, by other methods, became rabid. Most of the survivors, when challenged intramuscularly with street rabies virus at six months, developed rabies. The results indicate that the skunk is much more susceptible to challenge virus standard rabies virus given intranasally than by the other methods used. When disease occurs following oral administration, infection may be associated with prolonged contact with buccal mucosa or accidental contact with nasal mucosa. Survivors had little or no protection when challenged intramuscularly with street rabies virus. |
