Abstract
Summary
Purified suspensions of both mature infectious elementary bodies and intermediate reproductive reticulate bodies of meningopneumonitis organisms were tested for NADH-cytochrome C reductase activity. Both intact and disrupted suspensions of reticulate bodies showed a relatively high enzyme activity. Intact elementary body preparations showed very low activity, but a 12-fold increase occurred when the organisms were disrupted by sonic treatment. The results indicate difference in envelope or membrane permeability at different developmental stages.
