THE bacterium which is described in this paper has been encountered
on several occasions during investigations on diseases of sheep on the
Romney Marsh, Kent. The particular diseases are known locally
by the terms "struck" and "gangrene". The term " struck " is
applied by the farming community to a rapid and fatal disease where
post-mortem examination reveals an acute inflammatory condition in
one or more of the following parts of the body : areas of muscular
tissue, organs in the abdominal cavity, and organs in the thoracic
cavity. The term "gangrene" applies to a similar disease in ewes
attacked within a few days after lambing.
From the investigations carried out during the past two years,
evidence shows that a number of species of pathogenic sporulating
anærobic bacteria may each separately be responsible for these diseases.
The particular bacterium now under consideration is one of the
number of species encountered, and is described separately because
it is of peculiar interest, as it has been recovered from the muscular
tissue where the lesions were in many ways similar to those of black-quarter, and because the bacteria resemble B. welchii, and may readily
be mistaken for that micro- organism unless careful and detailed
bacteriological examinations are made.
The bacteria probably belong to a hitherto unrecognised species,
and if this be so, I suggest that the bacterium should be named
B. paludis; this name is proposed because the bacteria have been
found causing disease in animals grazing and living on a marsh.
