Abstract
This study analyzed 50 varicella zoster virus (VZV) samples collected during 2004 to 2007 from patients with VZV infection, who were treated at the National Center of Communicable Diseases, Ulan-Bator, Mongolia. The method based on amplification of specific DNA fragments of the ORF21, ORF22, and ORF50 genes was used, followed by the sequencing and detection of the status of characteristic point mutations in these fragments. The results indicated that the collected samples belonged to genotypes J (62%), M1 (18%), E1 (12%), E2 (4%), and M2 (4%). Moreover, restriction endonuclease polymorphism in ORF 62 for the cleavage site SmaI and MspI, in ORF 38 and ORF 54 for the cleavage site PstI and BglI were analyzed. All the samples were Sma- Msp-. All samples with genotype E were Pst+ Bgl-; all samples with genotype M1 and M2 were Pst+ Bgl+. Out of 31 samples with genotype J, 29 and 2 were Pst+ Bgl+ and Pst- Bgl+, respectively. The study could identify the genotypes of VZV circulating in Mongolia and confirmed the absence of mutations characteristic for the vaccine strain.
