  20. MORTALITY OF INVASIVE ASPERGILLOSIS • Variation due to: • timing of intervention • timely diagnosis • patients’ defense system • treatment given

  21. 97% 42% MORTALITY OF INVASIVE ASPERGILLOSIS • Variation due to: • timing of intervention • timely diagnosis • patients’ defense system • treatment given

  22. GROWTH OF ASPERGILLUS 1-2 cm per 24 hours
