Hemagglutinating Virus Isolated from Cat Scratch Disease

Publication Date



Dodd, Graber, and Anderson (1959) demonstrated a hemagglutinin in pus from ten cases of cat scratch disease which was inhibited by antiserum to the agent and by sera from some cases of the disease.

The present report concerns the properties of a hemagglutinating virus, which is antigenically related to herpes simplex, encountered in chick embryos inoculated with pus from suspected cases of the disease. The virus is demonstrable only by hemagglutination of rabbit and rat red cells after inhibitors are removed from the allantoic fluid and lacks the typical virulence and cytopathogenic properties of herpes virus.
