Background and Aims: Newcastle disease (ND) is one of the contagious viral diseases in avian species. Recently, several ND outbreaks in pigeon caused by pigeon paramyxovirus serotype-1 (PPMV-1) have been reported din limited numbers from Iran and phylogenetic studies have been conducted on partial sequence of NDV fusion (F) gene. Materials and Methods: In the present study, ten PPMV-1, named Pigeon_paramyxovirus1_isolate_pigeon/Iran/UT_EGV1-10/2018, isolated from infected pigeons, and were subjected to partial sequencing. All isolates showed MDT of 74-80 hours, thus categorizing them as mesogenic. Results and Conclusion: The phylogenetic analysis based on the F gene sequence revealed the isolates belong to XXI.1.1 subgenotype. According to BLAST results, the partial genome of UT-EGV1-10 had high homology with some Russian and Egyptian strains (the highest was 96.55%). The information obtained from this study can be useful in preventive measures for ND caused by PPMV-1 in pigeons.
