Abstract:
Objective To study human bocavirus (HBoV) induced respiratory tract infection in Guangdong Province in China. Methods HBoV was deteced by using polymerase chain reaction (PCR) technology and was identified by DNA sequences. Results One strain of HBoV was detected and identified from 50 samples collected from children with acute respiratory tract infections. This was the first clinical case of HBoV infection reported in Guangdong and was named as GD-1 strain. The HBoV capsid protein (VP) gene amplified from the specimen by PCR was identified by sequencing and was compared with gene sequences in GenBank. Phylogenetic trees were constructed for sequence homology analysis. The nucleotides similarities between GD-1 and Beijing strains, France strains and Canada strains were over 98%, while the simlilarity was over 36% compared with Korea KNIH-2K6GJ2713 strain and over 77% compared with US NH4549 strain. Conclusion HBoV infection does exist in Guangdong Province. It is valuable to start systemic study on it.
