Rapid discrimination between human immunodeficiency virus type 2 groups A and B by real-time PCR.

چکیده
We studied the feasibility of genotyping human immunodeficiency virus (HIV) type 2 groups A and B by real-time PCR. Two group-specific PCRs were developed. Real-time genotyping of 22 samples of genotype A, 10 samples of genotype B, and the isolate of new group H were compared to genotyping by sequencing and phylogeny. The group-specific PCRs specifically identified 84.3% of group A or B samples; isolate H was not detected. This method allowed rapid and specific discrimination between HIV-2 groups A and B and could be a useful tool for molecular epidemiological studies.

Background and purpose: Recently, use of enzyme-linked immunosorbent assay (ELISA) and rapid Immunochromatographic test (ICT) in diagnosis and screening of patients with hepatitis B reduced the risk of hepatitis during blood transfusion. However, the incidence of hepatitis B is very high in high-risk patients such as hemodialysis, thalassemia and hemophilia which receive a lot of blood transfus...

During 2010-2011, Real-time PCR procedure was used to detecting FMDV RNA on 147 epithelium samples from the field. In this survey, for Real-time PCR from 3D gene segment as conserve region selected for tracking all of seven serotypes FMDV. The assay detected the viral RNA in all serotypes of FMDV. The rRT-PCR specifically detected FMD virus in sample with greater sensitivity than our convention...
