False negatives, misleading positives, and assay limitations can complicate leptospirosis diagnosis. Jane Sykes, BVSc, DACVIM (SAIM), PhD, MPH, MBA, FNAP, explains where veterinarians most often go wrong and how to interpret results in context.

Jane Sykes, BVSc, DACVIM (SAIM), PhD, MPH, MBA, FNAP, discusses what researchers still don’t know about canine leptospirosis and where progress may be coming.

New evidence suggests long-held assumptions about risk, vaccination, and exposure may be leaving dogs unprotected, explains Jane Sykes, BVSc, DACVIM (SAIM), PhD, MPH, MBA, FNAP, in this interview with dvm360.

Jane Sykes, BVSc, DACVIM (SAIM), PhD, MPH, MBA, FNAP, discusses how urban environment, social conditions, and vaccination gaps have been reshaping how and where veterinarians encounter leptospirosis.

The 2023 ACVIM leptospirosis consensus marks a turning point in canine care, shifting vaccination to a universal core protocol while updating diagnostic standards and shortening handling precautions.

Rats and other reservoir hosts can carry leptospirosis without illness, shedding bacteria into the environment while dogs and people become the visible victims of infection, explains Jane Sykes, BVSc (Hons), DACVIM (SAIM), PhD, MPH, MBA, FNAP.

Dr Sykes outlines why new evidence on leptospirosis epidemiology and safer vaccines led to a recommendation for annual vaccination of all dogs.
