Objective. To research the molecular characteristics of two HPAI strains – A/Ch/Syvash/02/05/H5N1 and A/Ch/Krasnogvardeysk/58/08/H5N1, which were identifi ed as representatives of the highly pathogenic H5N1 viruses. Methods. RNA extraction, real-time polymerase chain reaction (PCR). Results. The phylogenetic studies revealed that the above mentioned strains belong to two various genetic lineages originated from the Eastern European strains isolated in 2005, but differ from the viruses introduced
