Davison, A. and Blaxter, M. L. (2005) An expressed sequence tag survey of gene expression in the pond snail Lymnaea stagnalis, an intermediate vector of Fasciola hepatica. Parasitology130, 539–552.

Unfortunately, an error was introduced during the authors' editing of the manuscript. Although Lymnaea stagnalis can host Fasciola hepatica under experimental conditions (Kendall, S. B. 1949, Nature163, 880–881), the impression was inadvertently given that L. stagnalis is a common intermediate vector in nature. The truth is that only some species of the genus Lymnaea are intermediate vectors for F. hepatica, such as L. truncatula.

Therefore, the title of the paper could be better as ‘An expressed sequence tag survey of gene expression in the pond snail Lymnaea stagnalis, an intermediate vector of trematodes’.

In the INTRODUCTION, the following line should be modified from ‘The life-cycle of F. hepatica in Lymnaea stagnalis is typical of the digenean platyhelminths …’ to ‘The life-cycle of F. hepatica in Lymnaea is typical of the digenean platyhelminths …’

Otherwise, the results and conclusions are not affected.
