A total of 474 serum samples from client owned Irish dogs were tested for the presence of antibodies to serovars Canicola, Icterohaemorrhagiae, Bratislava, Autumnalis, Pomona, Altodouro, Grippotyphosa, Mozdok, Hardjobovis and Ballum. Six per cent of dogs presented to veterinary practitioners for problems unrelated to leptospirosis showed evidence of prior exposure to leptospiral serovars belonging to the serogropus Ballum, Australis, Pomona and Sejroe. One unvaccinated dog suspected to have leptospirosis showed seroconversion to serogroup Icterohaemorrhagiae. Based on these results the authors conclude that canine exposure to serogroup Ballum should be monitored because dogs may serve as sentinels for this serovar in the environment. Vaccination with multivalent vaccines containing serovar Bratislava in addition to serogroups Icterohaemorrhagiae and Canicola is advisable.
