Current situation and genomic characterization of fowlpox virus in lower Egypt during 2022.

ABSTRACT: A total of 45 samples of vaccinated and non-vaccinated layer chickens were collected from farms in the Egyptian governorates of Sharqia, Ismailia, Menofia, Gharbia, Kafr El Sheikh, Qalyubia, and Dakahlia in the year 2022. They exhibited nodular lesions on their combs, mouth corners, and eyelids, suggesting they were infected with pox disease, which was associated with a 3 to 5% mortality rate. The samples were grown on the chorioallantoic-membrane of embryonated chicken eggs to ensure their viability. In both vaccinated and non-vaccinated farms, 35 of 45 virus isolates were confirmed positive via polymerase chain reaction (PCR) of fpv167 (P4b), based on the amplicon length of the fpv167 gene locus. The 6 strains from various Egyptian governorates were chosen for sequencing and genetic char
