Histology of the murine lungs (H&E stain) in normal and γδ T-cell-deficient mice following intranasal infection with a nonlethal dose of log-phase cells of N. asteroides GUH-2. (A) γδ T-cell knockout mice at 3 days after infection; (B) C57BL/6J wild-type mice at 3 days after infection; (C) γδ T-cell knockout mice at 5 days after infection; (D) C57BL/6J wild-type mice at 5 days after infection; (E) γδ T-cell knockout mice at 7 days after infection; (F) C57BL/6J wild-type mice at 7 days after infection. Original magnification, ×100. Bars, approximately 50 μm.
