Psittacid herpesvirus 1 (PsHV-1) is the causative agent of Pacheco's disease, an acute, highly contagious, and potentially lethal respiratory herpesvirus infection in psittacine birds, while infectious laryngotracheitis virus (ILTV) is a highly contagious and economically significant avian herpesvirus which is responsible for an acute respiratory disease limited to galliform birds. The complete...

We have cloned and sequenced the KpnI L and M restriction fragments of infectious laryngotracheitis virus (ILTV, gallid herpesvirus 1) DNA, which are localized adjacently at the right end of the unique long region of the genome. Within the 6930 bp DNA sequence six complete open reading frames (ORFs) were identified. The predicted amino acid sequences of four of them exhibit significant homologi...

The 24 kbp KpnI restriction fragment A from the unique long genome region of infectious laryngotracheitis virus (ILTV, gallid herpesvirus-1) has been sequenced. The analysed region contains 14 open reading frames sharing homology with conserved alphaherpesvirus genes. Arrangement of the UL6 to UL20 homologues of ILTV is almost identical to that found in the herpes simplex virus type 1 genome. A...
