Sequence heterogeneity in a repetitive DNA element of Fasciola
1998
Kramer, F. | Schnieder, T.
A repetitive DNA sequence used as a specific probe for Fasciola hepatica infections in snails was examined in F. hepatica and Fasciola gigantica (36 individuals) specimens from five continents. The degree of intraspecific identity ranged from 79 to 99% in F. hepatica and from 93 to 99% in F. gigantica. The interspecific identity ranged from 81 to 100%, confirming the suggestion that the DNA probe sequence could be used worldwide as an epidemiological tool for the examination of the intermediate host snail in fasciolosis. Differentiation between F. hepatica and F. gigantica infections in snails was not possible using the probe.
