Ein zwei Wochen alter Wellensittich (Melopsittacus undulatus) wurde tot in derVoliere aufgefunden und zur Untersuchung auf Erkrankungs- und Todesursacheeingesandt. Makroskopisch wurden ein schlechter Ern\u00e4hrungszustand undwenige Federn festgestellt. Histopathologisch fanden sich in epithelialen undmesenchymalen Geweben zahlreiche, bis zu 15 amp;#956;m im Durchmesser gro\u00dfe, intranukle\u00e4re,amphophile bis basophile Einschlussk\u00f6rperchen mit hellem Zentrum.Des Weiteren wurde eine Dysplasie der Federn mit Retentionshyperkeratose derFederfollikel beobachtet. Elektronenmikroskopisch wurden etwa 35 nm gro\u00dfeViruspartikel im Federfollikelepithel nachgewiesen. Nachdem der NachweisAvi\u00e4rer Polyomaviren in einer nativen Hautprobe des Tieres negativ verlief, gelanges, virale DNA in formalin-fixiertem Nierengewebe, das viele Einschlussk\u00f6rperchenaufwies, nachzuweisen. Dar\u00fcber hinaus gibt dieser Artikel eine \u00dcbersicht \u00fcbervirus-induzierte Erkrankungen von Psittaciden, die Einschlussk\u00f6rperchen verursachen,wie Avi\u00e4res Pockenvirus, Psittacine Beak and Feather disease-Virus, Avi\u00e4resAdenovirus, Psittacines Herpesvirus und Papillomvirus.
