Abstract

Summary

A total of 3,836 tropicorbid snails, , from 13 localities in Louisiana collected between 1959 and 1966 proved to be nonsusceptible to infection with a Puerto Rican, a Brazilian (Minas Gerais), and a St. Lucian strain of . Among these were snails collected from the same locality where susceptible snails had been found in earlier studies in 1945 through 1953. It is possible that the snails found at present in these lakes have been recently introduced from a nearby drainage system (Mississippi River) and that the susceptible snails may still exist in other parts of the same drainage system (Amite River), but none has yet been found.
