This work saved the French silk industry, which had been crippled by the disease pèbrine. After five years of research on the problem, Pasteur found the germs of this disease not only in the silkworms but also in their moths and ova. He demonstrated a successful method of overcoming the plague by a systematic microscopic examination of ova with elimination of all those found to be diseased.
