Leptospirosis in wildlife in Brazil: isolation of serovars canicola, pyrogenes and grippotyphosa.

The isolation of serovar canicola from the Norway rat (Rattus norvegicus), shows that it is a reservoir of canicola and is therefore significant from an epidemiological point of view. The isolation of pyrogenes and grippotyphosa from a water rat, Nectomys squamipes is also described.
