| association between mycobacterium tuberculosis beijing/w lineage strain infection and extrathoracic tuberculosis: insights from epidemiologic and clinical characterization of the three principal genetic groups of m. tuberculosis clinical isolates. | clinical strains of mycobacterium tuberculosis can be divided into three principal genetic groups based on the single-nucleotide polymorphisms at the katg gene codon 463 and the gyra gene codon 95. one subgroup of genetic group 1, the beijing/w lineage, has been widely studied because of its worldwide distribution and association with outbreaks. in order to increase our understanding of the clinical and epidemiological relevance of the genetic grouping of m. tuberculosis clinical strains and the ... | 2007 | 17166963 |
| [subtype and sequence analysis of gag genes among hiv-1 strains circulating in beijing during 2007]. | to investigate the subtype distribution and sequence characteristics of hiv-1 strains prevalent in beijing during 2007 and to analyze the relationship between distribution of hiv-1 subtypes and transmission routes, we collected the anti-conglutinated whole blood samples from hiv-1 newly infected individuals in beijing during 2007 and separated plasma specimens from the aamples. rnas were extracted and the gag genes from the various samples were amplified by rt-pcr and nest-pcr. the pcr products ... | 2009 | 20077931 |
| [env gene sequencing and hiv-1 subtyping of infected msm from beijing]. | objective: to comprehend the latest hiv-i epidemic tendency and the character of v3 loop in msm population of beijing. methods; the c2-v3 regions of the hiv envelop gene were amplified by nest-pcr and sequenced from 11 hiv-l-infected msm in beijing in 2007. the subtype and sequences of v3 loop was analyzed. results there are 4 subtype b strains, 5 crf ae, 1 crfo7bc and 1 crf15-01b strains within all 11 strains. there are five types of central motifs of the 11 samples, in which gpgr and gpgq are ... | 2009 | 20108772 |
| high genetic diversity of hiv-1 was found in men who have sex with men in shijiazhuang, china. | men who have sex with men (msm) have become one of the populations with severely hiv prevalence in china. however, very few genetic studies have been done on hiv-1 spreading in this population. in this study, the genetic characterization of hiv-1 strains prevalent in the msm in shijiazhuang, china, was analyzed basing on the hiv-1 full-length gag, pol, and partial env gene. 21 drug-naïve hiv-1 sero-positive patients were enrolled into the study. full length gag, pol, partial env genes and some n ... | 2011 | 21645646 |
