Abstract

The present study aimed to characterize chicken infectious anemia virus isolated from various outbreaks in Thailand during 2008-2011, and compare them with other strains from the GenBank database using molecular and bioinformatic techniques. For this purpose, thirteen samples were collected from eight commercial farms affected by chicken infectious anemia outbreak. All were positive by PCR and grouped in 2 clusters with phylogenetic analysis based on nucleotide sequencing, consistent with amino acid sequence analysis of the VP1 gene in the hypervariable region. All of the thirteen strains were closely related to Chinese and Japanese strains with a high percentage of sequence similarity and was distantly related to vaccine strains used in Thailand.
