The relatively small number of reported cases of mixed infection resulting from the simultaneous occurrence of the Plasmodium malariæ and Bacillus typhosus in the same patient is sufficient pretext for the relation of the following case, which presents many features of unusual interest and which, furthermore, may prove to those skeptical as to the possibility of a double infection, that the same host may, and sometimes does, entertain two guests whose morphologic appearance and biologic habits so widely differ:
Patient.
—On June 2, 1905, I was called to see Mrs. A. C. S., Scotch, aged 35. She complained of frequent micturition, accompanied by vesical tenesmus. The marked irritability of the bladder was most troublesome at night, requiring the patient to leave her bed every few minutes. Heat and opium suppositories afforded some relief by inducing sleep.
Course of Diease.
—The next morning a chill caused me to be sent for.
