  abstract = {{D}epending on the extent of evolutionary divergence among parent taxa, hybrids may suffer from a breakdown of coadapted genes or may conversely exhibit vigour due of the heterosis effect, which confers advantages to increased genetic diversity. {T}hat last mechanism could explain the success of hybrids when hybridization zones are large and long lasting, such as in the water frog hybridization complex. {I}n this hybridogenetic system, hybrid individuals exhibit full heterozygosity that makes it possible to investigate in situ the impact of hybridization. {W}e have compared parasite intensity between hybrid {R}ama esculenta and parental {R}. lessonae individuals at the tadpole stage in two populations inhabiting contrasted habitats. {W}e estimated intensity of {R}. lessonae individuals at the tadpole stage in two populations inhabiting contrasted habitats. {W}e estimated intensity of {G}yrinicola sp. ({N}ematoda) in the gut, {E}chinostome metacercariae in the kidneys and {H}aplometra cylindracea in the body cavity (both species belong to {T}rematoda). {D}espite high sampling effort, no variation in parasite intensity was detected between taxa, except a possible higher tolerance to {H}. cylindracea in hybrid tadpoles. {T}he low effect of hybridization suggests efficient gene co-adaptation between the two genomes that could result from hemiclonal selection. {V}ariation in infection intensity among ponds could support the {R}ed {Q}ueen hypothesis.},
