Micrograph of a melanophage, which is a macrophage containing melanin pigment. It is surrounded by red blood cells. H&E stain.
An active J774 macrophage is seen taking up four conidia in a co-operative manner. The J774 cells were treated with 5ng/ml interferon-γ one night before filming with conidia. Observations were made every 30s over a 2.5hr period.
Two highly active alveolar macrophages can be seen ingesting conidia. Time lapse is 30s per frame over 2.5hr.
