Ran across this reference in pursuit of an answer to Loren's question
about limberneck. It meshes with a number of threads on SANET
recently, including soil health as a contributor to overall health,
and the value of "old" information/research.

1940 The soil as a source of microorganisms antagonistic to
J. Bacteriol. 40, 581-600.
The soil contains a number of different types of microorganisms
antagonistic to various bacteria belonging to gram-positive and
gram-negative groups. By
enriching the soil with the specific bacteria, the corresponding
antagonists increase and can be readily isolated. This has been done
most readily by the use of an agar medium containing viable cells of
the specific organism as the sole available nutrient.
Out of a number of antagonistic organisms isolated from the soil, two
were studied in greater detail, one a bacterium belonging to the
aeruginosa group, and the other an Actinomyces. These organisms were
found to inhibit the growth of several gram-negative bacteria, as
well and, even to a
greater extent, of numerous gram-positive bacteria.
The active substance produced by the two antagonists was found to be
largely thermostable; it passed through a Seitz filter, it was
removed by charcoal and was, partly at least, ethersoluble. Highly
active preparations were obtained which inhibited, in very dilute
solutions, the growth of Escherichia coli, Brucella abortus,
and of many other bacteria.
The active substance had also a strong bactericidal effect upon
Escherichia coli (215,000,000 viable cells) and of Brucella abortus
(68,000,000 viable cells).
The active substance of the two antagonists was found to reduce, in
very low concentrations, the bacterial populations of natural
substrates, such as milk; when
added to aggar it prevented the development of the great majority of
soil bacteria and actinomycetes, but not of fungi.

1967 Clostridium botulinum type F, seasonal inhibition by Bacillus
Science 155, 89-90.
Clostridium botulinum type F has been identified during the summer
months in mud samples from a small stream. Its absence during the
period from October
to April in these mud samples is attributed to the presence of
Some peer-reviewed, published evidence that when a system is in
balance, and soil is healthy, specific pathogens stand less of a
chance of flourishing.
