This video from 3 Minutes of Fun shows eosinophil granulocytes chemotaxing to an IgE-opsonized multicellular parasite. During a normal immune response to helminths, eosinophils degranulate and release cationic granule proteins (major basic protein [MBP], eosinophil cationic protein [ECP], eosinophil peroxidase [EPO], and eosinophil-derived neurotoxin [EDN]) to destroy pathogens too large to be endocytosed by phagocytes. They also induce mast cells and basophil granulocytes to degranulate, thus releasing histamine and proteolytic enzymes.
Russian photographer Nick Lariontsev filmed this time-lapse showing how mold grows. This is a mixed group of Aspergillus fumigatus, Botrytis spp., Mucor spp., Trichoderma spp., and Cladosporium spp.
