Alina Wieliczko Anna K. Matczuk Katarzyna Ćwiek

Chorobę dużej wątroby i śledziony (Big Liver and Spleen Disease - BLS), opisywaną także w literaturze jako syndrom zapalenia wątroby i splenomegalii kurcząt (Hepatitis- Splenomegaly Syndrome - HSS) wywołuje ptasi wirus zapalenia wątroby typu E (avian Hepatitis E Virus - aHEV) należący do rodziny Hepeviridae, rodzaju Orthohepevirus. W obrębie tego rodzaju opisano 4 gatunki nazwane Orthohepevirus od A do D.
