Summary

The importance of the mite Laelaps agilis (Parasitiformae) for the transmission of the Hepatozoon species living in the blood of Apodemus sylvaticus and Apodemus flavicollis (Hepatozoon sylvatici) is examined. With this mite the experimental transfer of the parasite to bred hosts of the same species was successful five times; for once, the transmission to a non-specific host (Clethrionomys glareolus) was also possible. Besides, an eventual stimulating effect emanating from the gonads of female mites to the development of parasites can be considered. Differences in the morphology of schizonts in the bone marrow and in the liver of infected Apodemus flavicollis are especially pointed out.

Zusammenfassung

Die Bedeutung der parasitiformen Milbe Laelaps agilis für die Übertragung des Waldmaus-Hepatozoons, Hepatozoon sylvatici, wird untersucht. Es gelang mit dieser Art eine fünfmalige experimentelle Übertragung des Parasiten auf gezüchtete, artgleiche Neuwirte, einmal auch in einen unspezifischen Zwischenwirt (Clethrionomys glareolus). Eine eventuelle gonadotrope Stimulation der Parasitenentwicklung von seiten geschlechtsreifer Milbenweibchen kann in Betracht gezogen werden. Auf die unterschiedliche Morphologie der Schizonten in Knochenmark und Leber infizierter Apodemus flavicollis wird besonders hingewiesen.
