Histopathological analysis of the inflammatory infiltrate profile in uninfected mice. The mice were submitted to three administrations of 20 μL of AWB (c and d) and of SAL (e and f) at five-day intervals (Scheme 1). The evaluation by light microscopy was performed by hematoxylin-eosin staining from the posterior region of the quadriceps muscle collected from mice 48 h after AWB and SAL injection (c-f) compared to samples obtained from untreated (a, b) animals. Original increments × 100 (a, c and e) and × 1000 (b, d and f). Arrows: inflammatory infiltrate
