IL6 and peritonitis: Regarding mixed infection of C. albicans and aerobic bacteria, studies have found that a model of peritonitis in mice coinfected with S. aureus and C. albicans caused more severe infections, produced more macrophage inflammatory protein-1α, recruited more neutrophils, caused inflammation in the local abdominal cavity, and increased interleukin (IL)-6 and PGE2 levels in the local abdominal cavity than when the mice were infected with one bacteria (Peters and Noverr, 2013).
