Fig. 5. SEM and TEM visualisations of the conidial surface of A. fumigatus: (a) reduction in the number of conidia in the compound-treated sample compared to the control; (b) compound-treated single conidium revealed loss of protrusions and a smooth surface compared to the echinulate conidial surface in the untreated control; (c) compound-treated single conidium showing loss of protrusions as well as the electron dense melanin layer of the conidial cell wall compared to control conidia showing protrusions and melanin deposition.
