Protective effects of alveolar macrophages in sublethal vaccinia infection. Mice (n = 10) were injected intratracheally with clodronate or saline liposomes and then infected 2 days later with 4 × 104 pfu of Vac-FL i.n. (A) Weight and (B) rectal temperature were measured daily to monitor overall progression of disease. Data are mean values ± SEM for percent weight loss or temperature, respectively. (C–E) Photon flux from regions-of-interest defined for the head (C), chest (D), and abdomen (E) on bioluminescent images over the course of infection. Data are mean values of background subtracted photon flux ± SEM. (F–I) Viral titers were quantified on days 3 and 5 post-infection (n = 3 per group) in the trachea (F), lung (G), brain (H), and spleen (I). Data are presented as mean values for viral titers ± SEM. 30 pfu/g tissue is the lower limit of detection for viral titers.
