              CRF55_01B 和 CRF68_01B 7 种 HIV⁃1 亚型和 6 种独特重组型。2014 年原发性耐药率为 4.95%,2016 年获得性耐药率为
              5.75%。5例感染者耐药情况发生变化,其中1例亚型发生变异。结论:无锡市HIV/AIDS人群HIV⁃1亚型多样且复杂,亚型及
              耐药变化大,应继续加强对亚型及耐药突变监测。

             [Abstract] Objective:To investigate the change of HIV subtypes and drug resistance in the follow⁃up HIV/AIDS population in
              Wuxi,Jiangsu in 2014 and 2016. Methods:HIV molecular epidemiological survey and follow⁃up study were carried out among HIV/
              AIDS patients who did not receive antiviral treatment in Wuxi in 2014. The basic information of the infected person was collected and
              DNA was extracted from blood samples. The pol,env,and gag gene fragments of HIV were amplified by nest⁃PCR and sequenced to
              determine the HIV genotype of the infected person. The pol sequence was submitted to the HIV drug resistance database for drug
              resistance mutation site analysis. In 2016,the same population was followed up and selected for antiviral treatment. HIV subtypes and
              drug resistance mutations were detected again,and the changes of subtypes and drug resistance in two years were analyzed. Results:A
              total of 117 HIV/AIDS cases were collected,and 234 samples were detected. Seven subtypes of HIV⁃1,CRF01_ AE,CRF07_ BC,B,
              CRF67_ 01B,CRF08_ BC,CRF55_ 01B,and CRF68_ 01B,and six unique recombinant types(URFs)were detected. The transmitted
              drug resistance rate was 4.95% in 2014,acquired drug resistance rate was 5.75% in 2016. The drug resistance of 5 cases changed,and
              one of the subtypes changed. Conclusion:The HIV⁃1 subtypes of HIV/AIDS patients in Wuxi are diverse and complex. The subtypes and
              drug resistance have changed greatly. Therefore,it is necessary to strengthen the surveillance of subtypes and drug resistance mutations.
