| first occurrence of mesocestoides sp. in a bird, the red-legged partridge, alectoris rufa, in spain. | larvae of mesocestoides sp. were found in the celomic cavity of one red-legged partridge (alectoris rufa) from azuara (aragón, north-eastern spain). this is the first report of this larval cestode occurring in birds from spain. none of the other 36 partridges from this area nor 150 partridges from other spanish localities were affected. the red-legged partridge does not seem to be an important link in the mesocestoides sp. life-cycle. | 2003 | 12743808 |
