|Contribution||b. Reported transmission of silkworm disease by means of corpuscles.|
|Notes||He transmitted the disease by exposure of silkworms to "corpuscles" found in diseased silkworms. Pasteur was not sure that the corpuscles reproduced; they were never present in healthy worms, but not always present in sick worms; and for these reasons Pasteut stopped short of claiming causation. As interpreted by Carter, Pasteur's evidence pointed to corpuscles as sufficient but not necessary for disease causation.|
