Candida albicans-Staphylococcus aureus Polymicrobial Peritonitis Modulates Host Innate Immunity

Abstract: bDespite advances in medical device fabrication and antimicrobial treatment therapies, fungal-bacterial polymicrobial peritonitis remains a serious complication for surgery patients, those on peritoneal dialysis, and the critically ill. Using a murine model of peritonitis, we have demonstrated that monomicrobial infection with Candida albicans or Staphylococcus aureus is nonlethal. However, coinfection with these same doses leads to a 40% mortality rate and increased microbial burden in the spleen and kidney b… Show more

“…Whether the non-S. aureus staphylococci significantly contribute to skin disease is currently unknown; in our previous study of atopic dermatitis, we observed a significant increase in the relative abundance of S. epidermidis concurrent with increases in S. aureus . A possibility is that these other staphylococci may share a mutualistic or commensal relationship with S. aureus by enabling greater resistance to antimicrobial peptides (Peschel et al 2001;SieprawskaLupa et al 2004;Lai et al 2007) or antibiotics (Wielders et al 2001;Berglund and Söderquist 2008) or by potentiating the S. aureus toxic response as with C. albicans (Peters and Noverr 2013). Alternately, these species could take advantage of inflamed skin conditions and co-colonize with S. aureus (Nilsson et al 1998;McCrea et al 2000;Cho et al 2001;Williams et al 2002).…”

“…The presence of Aspergillus did not differ in patients on antifungal medications with activity against Aspergillus compared with patients without a history of antifungal agents with activity against Aspergillus, again highlighting the significant skin microbial differences observable in PID patients in the absence of use of antimicrobial agents. In addition, coinfection of certain C. albicans isolates with S. aureus can result in infectious synergism with enhanced toxicity and host inflammation (Peters and Noverr 2013).…”

“…Показано, что распростра-ненный гнойный перитонит (РГП) протекает на фоне иммунодефицита, а в терминальной стадии (полиорганной недостаточности) им-мунная недостаточность наиболее выражена [4,18]. Предполагается, что нарушения в иммунной системе имеют решающее значение для возник-новения различных осложнений заболевания.…”

“…Нейтрофилы представляют собой высокоре-активный тип клеток иммунной системы, они быстро мобилизуются в очаг воспаления, от их фагоцитарной активности во многом зависит эффективность противомикробной защиты ор-ганизма [4,5,18]. Доказано, что нейтрофильные гранулоциты являются не только эффекторны-ми (фагоцитирующими) клетками, но и регуля-торными, так как синтезируют широкий спектр цитокинов, которые также включаются в регу-ляторный комплекс иммуновоспалительных реакций [4,14,27].…”
