PTPRC and infection: At 2-weeks post infection with S. stercoralis, the CD45+ lymphocyte population in humanized mice was 14% ± 1.4 of the lymphocyte gate and granulocyte gate based on forward and side scatter, which was statistically lower than the 71% ± 35 in HTLV-1 infected and 87% ± 15 in HTLV-1/S. stercoralis coinfected animals.
