CohortThe clinical isolates A. fumigatus NCCPF 770078 and A. flavus NCCPF 761090 were provided by the Post Graduate Institute of Medical Education and Research, Chandigarh, India. Cultures were grown and maintained by regular subculturing on yeast peptone glucose [(YPG; yeast extract 0.3 %, peptone 0.5 %, glucose 1 % (w/v)] agar medium at 37 °C. New Zealand White rabbits were immunized with purified A. fumigatus and A. flavus GM fractions mixed with complete Freund’s adjuvant.

Disease Introduction MechanismHuman invasive aspergillosis (IA) leads to high mortality, especially in immunocompromised patients. Over 10 million immunocompromised patients are at risk of IA and >200 000 cases are reported annually worldwide. Aspergillus fumigatus is the most common aetiological agent for aspergillosis globally, while Aspergillus flavus is more prevalent in India.
