Publikováno v: Emerging Infectious Diseases, Vol 9, Iss 12, Pp 1523-1530 (2003)

Phylogenetic analysis of a collection of 103 E1 gene sequences from rubella viruses isolated from 17 countries from 1961 to 2000 confirmed the existence of at least two genotypes. Rubella genotype I (RGI) isolates, predominant in Europe, Japan, and t

Molecular characterization of ambiguous mutations in HIV-1 polymerase gene: implications for monitoring HIV infection status and drug resistance.

Autor: Du-Ping Zheng, Margarida Rodrigues, Ebi Bile, Duc B Nguyen, Karidia Diallo, Joshua R DeVos, John N Nkengasong, Chunfu Yang

Publikováno v: PLoS ONE, Vol 8, Iss 10, p e77649 (2013)

Detection of recent HIV infections is a prerequisite for reliable estimations of transmitted HIV drug resistance (t-HIVDR) and incidence. However, accurately identifying recent HIV infection is challenging due partially to the limitations of current
