title: Canine encephalitozoonosis in kennels and the isolation of Encephalitozoon in tissue culture.
abstract: The protozoan Encephalitozoon was isolated in primary kidney cultures from dogs originating from three separate outbreaks of encephalitozoonosis in kennels. The disease was characterized by a fading syndrome in young puppies with nervous signs developing in some cases. It was not possible to reproduce the clinical disease with cultured organisms in either normal dogs or dogs immunosuppressed with methylprednisolone. The organisms were, however, reisolated in primary culture from two immunosuppressed dogs but not from other experimentally infected dogs. The freezing of Encephalitozoon organisms in liquid nitrogen is described.
