How is lepto treated in cows?
Cattle with acute leptospirosis can be treated with the label dosage of tetracycline, oxytetracycline, penicillin, ceftiofur, tilmicosin, or tulathromycin. Leptospires also are highly susceptible to erythromycin, tiamulin, and tylosin, although these antibiotics cannot be relied on to remove the renal carrier state.
