Migration inhibition factor study in Histoplasma capsulatum
Abstract
Mice sublethally infected with viable Histoplasma capsulatum or immunized with merthiolate-killed yeast phase cells showed decreased mortality on subsequent challenge infection as compared to controls. Migration inhibition (MI) assays using peritoneal and spleen cells from immunized but unchallenged mice showed no parallel correlation with percent mortality. MI assay indices fluctuated without concomitant changes in resistance to challenge injection with live yeast phase cells. Viable vaccines induced greater resistance to challenge infection than killed cells, although both were comparable in sensitizing ability as measured by MI assay techniques with this mouse model.
