Five avian infectious bronchitis virus (IBV) isolates were isolated from broiler chickens showing respiratory and renal lesions. The isolated strains were characterized by reverse transcriptase polymerase chain reaction and sequence analysis of the hypervariable region 3 of the S1 spike glycoprotein gene. Three out of five isolates formed a distinct phylogenetic group with the Egypt/Beni-Suef/01 variant (Var 1). Two of the five isolates showed 89 and 84 % amino acid sequence identity and 89 and… CONTINUE READING
