   • 1865 April 27, George Child, “Further Experiments on the Production of Organisms in Closed Vessels”, in Proceedings of the Royal Society of London, volume XIV, London: […] Taylor and Francis, […], page 184:

     In the remaining three, where pea-meal or hay were employed, there the bacteriums were seen. So also in the other series, the one case in which nothing was found was a case in which flour was used, and in the remaining five the most numerous and distinct bacteriums were seen in the hay infusion.

     The normal microzymas of plants and of animals may develop into bacteriums; and many forms of both may exist in the same plant. The inoculation of the bacterium in a plant or animal causes their increased number, not by multiplication, but by so modifying the medium that the normal microzymas more readily develop themselves into bacteriums.

   • 1873, “Bacterium”, in George Ripley, Charles A[nderson] Dana, editors, The American Cyclopædia: A Popular Dictionary of General Knowledge, volume II, New York, N.Y.: D. Appleton and Company, […]; London: […], page 208, column 1:

     Differences in the molybdenum iron proteins from these two bacteriums are reflected in e.p.r. titrations, the relative reduction sequence of the redox centres, their midpoint reduction potentials, and the relaxation behaviour of the S=3/2 e.p.r. signal.
