• Leptospirosis occurred in a 45-year-old man with presumed infection from an exposure to contaminated water at his source of employment. An intensive epidemiological investigation, including serological examination of all family members and pets and cultures on the patient and his family pets (cats and dogs), proved that the leptospiral organism was acquired by the patient's exposure to his dogs. The risk of acquiring infection from dogs that are asymptomatic and vaccinated is emphasized by this report.
