title: Studies on immunity to reinfection with Schistosoma mattheei in sheep and cattle.
abstract: Few experiments have been reported on immunity to reinfection in domestic stock. The degree of resistance to reinfection with S. mattheei was studied in cattle and sheep. On the basis of the results, the only evidence of acquired immunity in calves and sheep is a reduction in the length of adult worms.
