In light of recent canine distemper virus (CDV) epidemics, we set out to
determine the historical significance of CDV infection in captive lions and
tigers in Switzerland. The retrospective case material consisted of 42 lion
and tiger necropsy cases from 1972 to 1992. Necropsy reports for all lions
and tigers were reviewed. All existing paraffin tissues were
immunohistochemically examined with a polyclonal antibody raised against
CDV. The results for 19 of the 42 lions and tigers were classified as
positive by immunohistochemistry; 23 results were negative or questionable.
The results for four animals (three positive and one negative ) were
further tested by in situ hybridization, and the results concurred with the
immunohistochemistry findings. CDV infection of large cats is older and
more widespread than previously thought. All large cats in captivity should
be immunized even if canine distemper is not believed to be a problem for
large cats in the area.
