||Occupational asthma to the slime mold Dictyostelium discoideum

||Dictyostelium discoideum is a slime mould that exists in a unicellular amoeboid form under certain nutritional conditions. In this form it produces unique lysosomal enzymes that are valuable in studying cell-to-cell signalling systems. A research microbiologist developed rhinoconjunctivitis and asthma after release of the organism from a pressurized canister. Immediate skin-test reactivity to whole and lysed organisms was demonstrated. Enzyme-linked immunosorbent assay results revealed IgE antibody against whole organisms, lysed organisms, and lysosomal enzymes with the strongest response being directed toward lysosomal enzymes. Pulmonary function testing showed a decline in forced expiratory volume in one second and forced expiratory flow after modified laboratory exposure to D. discoideum. This case represents the first report of occupational rhinoconjunctivitis and asthma from slime mould.
