Lucet describes a septicæmia of chickens and turkeys accompanied by
dysenteric discharges. The microbe resembles the bacillus gallinarum of
Klein (see Vol. II, p. 254), even in the immunity of pigeons and rabbits
when injected subcutem. Rabbits, however, suffer when injected
intravenously. The probability is that this bacillus is identical with
that of Klein. Yet in this whole class of microbes of the colon group,
variations, apparently superinduced by environment, appear to result at
times in a deadly pathogenesis for different genera, and epizoötics
differing from each other.
