Varying infectivity ofTaenia taeniaeformis for rats and mice

Abstract
Strains ofTaenia taeniaeformis were shown to possess markedly differing infectivities for Sprague-Dawley rats and CF1 mice. Strains from Scotland, Belgium and Iraq were more infective for mice than rats while this situation was reversed with a Malaysian strain. There were also differences in their ability to infect hosts of different ages within the range 3–12 weeks of age.
