Abstract:
OBJECTIVETo investigate the mutations in nucleotide and amino acid level in HPV61, 83 and 84 Shanxi isolates.
METHODSAmplified fragments of HPV61, 83 and 84 from human papillomavirus (Human papillomavirus, HPV) molecular epidemiologic survey of Shanxi Province using HPV consensus primers MY09/11 were cloned in pMD18-T vector, and the plasmids were sequenced, then nucleotide sequences and amino acid sequences were analyzed.
RESULTSHPV61 and HPV83 isolates were consistent with reference strains U31793 and AF151983 in nucleotide sequences; four mutations of nucleotide (C6760T, T6931C, T6951C and C6987A) were found in HPV84 isolate compared with reference strain AF293960, among which C6987A resulted in D441E and the amplified sensitivity of standard sample of HPV61 using primers MY09/11 was higher than that of HPV83 and 84.
CONCLUSIONHPV61 and HPV83 isolates were consistent with reference strains, four mutations of nucleotide and one mutation of amino acid were found in HPV84,the amplified sensitivity of standard sample of HPV61 using primers MY09/11 was the highest among those three isolates.
