Foshay, a microbiologist at the University of Cincinnati, suspected CSD to be a possible manifestation of tularemia. On meeting Debre in 1947, the 2 investigators compared notes on "catscratch disease" (Debre) and "cat fever" (Foshay). Foshay had produced an antigen from the pus of affected patients and achieved what was believed to be a diagnostic reaction after intradermal injection. Debre and his colleagues subsequently developed a similar antigen and demonstrated reactions in both old and new cases of CSD.

These results were presented and published in 1950. [17] These investigators also recorded failure of transmission of CSD to 15 different species of animals and possible human-to-human transmission in 1 of 4 cases.
