Sažetak
Golublji paramiksovirus tipa 1 (PPMV-1) smatra se antigenskom varijantom njukaslske bolesti koja uzrokuje visoku smrtnost i znatne ekonomske gubitke u peradarskoj industriji. Patogenost virusa PPMV-1 u pilića međutim još uvijek nije jasna. U ovom je radu provedena biološka karakterizacija PPMV-1 izoliranog iz golubova za koje se sumnja da su oboljeli od njukaslske bolesti te je istražena njihova patogenost u SPF pilića. Filogenetsko stablo i evolucijske udaljenosti otkrili su da novi izolat pripada podgenotipu VI.2.1.1.2.2 virusa njukaslske bolesti (NDV). Unatoč motivu u mjestu cijepanja F-proteina koji sadržava sekvenciju 112RRQKR↓F117 povezanu s virulentnim sojevima NDV-a, vrijednosti MDT-a i ICPI-ja izolata pokazale su mezogene značajke. Ovo probno istraživanje je pokazalo da su izolati PPMV-1 slabo patogeni u pilića, dok u golubova uzrokuju lezije na više organa i tkiva.
