Leukocyte recruitment is not impaired by HKH20. FACS analysis of peritoneal lavage from noninfected mice injected with PBS (A) or HKH20 (B), mice injected intraperitoneally with 5 × 10⁶ CFU S pyogenes in the absence (C) or presence (D) of 200 μg HKH20. Peritoneal lavage was analyzed 18 hours after infection. All leukocytes are CD45 positive, and neutrophil populations (red) are separated from monocyte populations (green) based on their side scatter pattern.
