The soils in which the berries were grown were also healthier, showing greater microbe growth.
The danger from this source is remote, as the microbe does not form spores within the animal body.
In the majority of instances, however, no local indication could be found marking the point at which the microbe was implanted."
The high temperature characteristic of this condition is no doubt injurious to the body itself, but it is frequently more so to the microbe which has invaded the organism; and thus fever, instead of now being regarded as a morbid condition to be suppressed by every means in our power, is considered to be a reaction of the organism tending to protect it by destroying the infection.
In process of time it became clear, however, that the worse the condition of a filter bed, in the then general acceptation of the term, the better it was as a microbe filter; that is to say, it was not until a fine film of mud and microbes had formed upon the surface of the sand that the best results were obtained.
