Rodent leptospirosis in Colorado.
A study was conducted to evaluate leptospirosis in brown rats (Rattus norvegicus), muskrats (Ondatra zibethicus) and mice (Mus musculus) in southeastern Larimer County, Colorado. Leptospira serotype icterohaemorrhagiae was isolated from fourteen of 143 feral brown rats, an infection rate of 9.8%. Serological evidence of infection with this stereotype was found in 66.4% of the rats. Serological evidence of L. serotype ballum infection was present in three of 17 muskrats. Leptospires were seen in histological sections of kidney tissue from two of 61 feral mice. No isolations were made from cultures and serology was not done on mice.
