Limited data are available regarding CMI among at - risk, seronegative, aviremic Egyptian healthcare workers (HCW), where HCV genotype 4 predominates. We investigated CMI responses among HCW at the National liver institute, where over 85% of the patients are HCV - infected. We quantified HCV - specific CMI in 52 seronegative aviremic Egyptian HCW using an interferon gamma (IFN - Þ) enzyme-linked immunospot (ELISpot) assay in response to 7 HCV genotype 4a overlapping 15mer peptide pools covering most of the viral genome. We also characterized the phenotype of the responding T cells to the HCV peptide pools by flow cytometry UR - http://172.23.153.220/th.pdf ER -
