Chromosome characteristics of Trichobilharzia franki Müller et Kimmig, 1994, causing swimmer's itch in the Western Germany, were described and compared with the karyotype of the sympatric species Trichobilharzia szidati Neuhaus, 1952. Karyotypes of both species are very similar: diploid sets consist of seven pairs of autosome chromosomes and one pair of sex chromosomes [2n = 16, n = 5m + 2sm + Zsm/Wst), the sex determining mechanism is ZZ in males and ZW in females and gross morphology of autosome pairs does not differ markedly. The only clear discriminative feature lies in the size and shape of sex chromosomes.
Résumé
Les caractéristiques chromosomiques de Trichobilharzia franki Müller et Kimming, 1994, agent de la dermatide des baigneurs en Allemagne de l'Ouest, ont été décrites et comparées avec le caryotype de l'espèce sympatrique Trichobilharzia szidati Neuhaus, 1952. Les caryotypes des deux espèces sont très proches: la série diploïde consiste en sept paires de chromosomes aulosomaux et une paire de chromosomes sexuels (2n = 16, n = 5m + 2sm + Zsm/Wst), le mécanisme de la détermination du sexe est ZZ chez les males et ZW chez les femelles et la morphologie générale des paires autosomales ne diffère pas considérablement. Le seul caractère distinctif clair se situe au niveau de la taille et la forme des chromosomes sexuels.
