Subviral

Subviral

Unter dem Begriff subzelluläre Erreger (engl. subcellular pathogens) oder subzelluläre Agentien werden verschiedene biologische Systeme zusammengefasst, die sich ohne eigenes zelluläres System und genetisch autonom vermehren können. Zu ihnen gehören neben den klassischen Viren, Viroiden und Virusoiden auch die nicht-extrazellulär vorkommenden („subviralen“) aber sehr eng verwandten Retroelemente wie Retroposons, LTR-Retrotransposon, Retroviroide, sowie DNA-Transposons und Satelliten-DNA. Subzelluläre Erreger ohne Nukleinsäure sind die Prionen.

Das Fachgebiet zur Erforschung der subzellulären Erreger ist die Virologie, von der auch wesentliche Methoden und Impulse zur Erforschung der subviralen Elemente ausgingen.
