Plain-English summary
In Greece, a study found that 12.9% of dogs tested had antibodies to certain strains of Leptospira, which can cause serious illness. The highest number of positive tests was for a newly identified strain called Altodouro, linked to clinical disease. Another strain, Bratislava, was also detected in a smaller percentage of dogs. These findings suggest that veterinarians may need to update dog vaccines to include these new strains to better protect pets from leptospirosis.

Abstract
A total of 855 sera from dogs in Greece were tested for antibodies to strains belonging to the Pomona, Grippotyphosa and Australis serogroups of Leptospira to assess exposure levels to these serogroups, possible associations with clinical disease and to evaluate whether these findings support the inclusion of additional serovars in dog vaccines. Antibodies were detected in 110 (12·9%) dogs. The highest seroprevalence (4·9%) was to the proposed novel serovar Altodouro belonging to the Pomona serogroup. This serovar also showed a statistically significant association with clinical disease. Serovar Bratislava antibodies were found in 3·4% of sera. Consideration should be given to the inclusion of serovars belonging to the Pomona serogroup and serovar Bratislava in future dog vaccines for the Greek market.
