Interesting results were also obtained when germination rate was evaluated at different temperatures. The percentage of germination markedly increased 3- to 10-fold for both A. fumigatus and A. flavus when temperature was increased from 20 to 30◦ C, and again 2- to 3-fold from 30 to 37◦ C. However at 41◦ C germination of A. fumigatus was still enhanced, whilst germination of A. flavus decreased by 45% (as compared with 37◦ C). The study shows that temperature influences growth of pathogenic Aspergilli, with A.

Fumigatus in rabbits. A wide variety of murine models of aspergillosis by A. fumigatus including intravenous, intratracheal or intranasal challenge, have been described. Although having a wide range of models is a very positive factor for many specific questions, the methodological differences amongst them have made direct comparisons of individual studies difficult . Furthermore, comparative studies in order to asses the interlaboratory variability of results obtained with the same experimental model are scarce.
