From: Decrease of virulence for BALB/c mice produced by continuous subculturing of Nocardia brasiliensis
Immunostaining of biopsies of lesions at five weeks postinfection. Top: Mouse inoculated with the non-subcultured isolate showing positive cells for anti-CD4 (left) and for anti-CD14 (right); 100×. Bottom: Foot-pad biopsy of mouse inoculated with T130. CD4+ (left) and CD14+ (right) T-cell lymphocytes are seen abundantly surrounding the microabscesses among the scarring tissue; (100×).
