Continuing search for the etiology of cat scratch disease

Abstract
Cat scratch disease patients (50) were tested for antibodies against candidate etiological agents [feline pneumonitis strains, lymphogranuloma venereum strain, trachoma-inclusion conjunctivitis strains, feline leukemia virus strains, feline syncytium-forming virus strain] with inconclusive results. Future research should emphasize new viral isolation methods to discover the elusive agent.
