INFECTION due to Leptospira canicola is common in dogs but is transmitted infrequently to man despite their close association. Although several hundred human cases are recorded in the world literature, the number reported in the United States has been relatively few. There are 15 reports * which cover a total of 32 sporadic cases and 2 accounts † of group outbreaks, which together amount to an additional 35 cases. It is probable that L. canicola was the offending organism in still another group outbreak in which 24 persons were involved.18

The following is a report of three cases of meningitis due to L. canicola admitted to the U. S. Army Hospital at Fort McClellan, Ala., in the summer of 1952. A study of the source of these infections and an epidemiological survey of the reservoir of infection at Fort McClellan is included.
