Summary

Two Persian cats kept in common, 3 months and 2 years old, presented a heavy infestation withCheyletiella mites. The cats showed itching and loss of hair. The animals' owners suffered from severe itching and redish papulae, particularly on those parts of the body which frequently got in contact with the cats.

After three treatments with Alugan® powder (Hoechst) the cats were freed from the mite infestation. The owners' skin affection disappeared soon without any treatment.

This is the first recovery ofCheyletiella mites on cats in Austria.

The mites were identified asC. blakei, although obvious differences between the first description and our material were encountered.C. blakei could be primarily separated fromC. parasitivorax according to the female tectum and the peritremata. Typically the sense organs on the genua of the first pair of legs are ovoid in shape. This feature, although morphologically variable, could be used as a diagnostic aid, if enough adult specimens are available.

Zusammenfassung

Zwei gemeinsam gehaltene Perserkatzen, 3 Monate und 2 Jahre alt, wiesen einen hochgradigenCheyletiella-Befall auf. Sie zeigten Juckreiz und Haarausfall. Die Tierbesitzer litten an stark juckenden geröteten Papeln, besonders an jenen Körperstellen, die häufig mit den Katzen in Kontakt kamen.

Durch drei Behandlungen mit Alugan®-Puder (Hoechst AG) wurden die Katzen von den Milben befreit, die Hautveränderungen der Tierbesitzer verschwanden bald von selbst.

In Österreich war bisher noch nieCheyletiella-Befall auf Katzen diagnostiziert worden.

Die Milben wurden der ArtC. blakei zugeordnet, es ergaben sich aber deutliche Unterschiede zwischen der Erstbeschreibung dieser Species und dem vorliegenden Material.

Die morphologische Abgrenzung gegenüberC. parasitivorax ist unter anderem anhand des weibl. Tectum und der Peritremata möglich. Die im typischen Fall ovoiden Sinnesorgane an den Genua des ersten Beinpaares wiesen beträchtliche Formvarianzen auf, sind aber besonders bei Vorliegen mehrerer adulter Milben, als diagnostisches Hilfsmittel geeignet.
