Details (age, sex, day of first [S1] collection after the onset of symptoms, occupation, contact with animals, and their highest microscopic agglutination test [MAT] titers against particular Leptospira serogroups) of 16 leptospirosis patients (P #1–14 and P #16–17), and one presumptive leptospirosis patient (P #15), from three human leptospirosis high-risk neighborhoods (Las Américas, Por Fin, and Rebolo) in Barranquilla. The highest MAT titers obtained against a particular serogroup are shown.
