Sarcocystis leporum was found in 42 of 173 (24.3 %) cottontail rabbits (Sylvilagus floridanus mearnsi) examined. Infections were not observed in cottontails less than 6 months old. Incidence rose from zero at age 5 months to 67% at age 12 months. Ninety per cent of cottontails 25-48 months old were infected. The age of individual cottontails was estimated from the eye lens weight.
