Study on effects of Lymnaeidae size on infection of Trichobil-harzia living in Huaihe River system / 中国血吸虫病防治杂志

ABSTRACT

F0.01(1,5)=16. 30,P0. 05). Conclusion Laboratory results thus suggest that infection intensity is related to snail size per se, whereas prevalence in the field is related to snail size only through the correlation between size and age. In addition, under these experimental conditions, infected snails were no larger than uninfected snails, so the gigantism snails observed in the field might not be attributable to Trichobilharzia-induced effect.
