Excerpt from The Antagonism Exhibited by Certain Saprophytic Bacteria Against the Bacillus Typhosus GaffkyThe effect which various agencies have on the life of Bacillus typhosus outside of the human body is a subject of great hygienic importance. Any information which will throw light on this subject is sure to receive due consideration.It is held by some Observers that this organism never finds conditions favorable for its development outside of the body, and that its existence in nature is measured by a few days, or at most a few weeks. Others, on the other hand, believe that this germ may lead a saprophytic existence, and that its life in nature may be prolonged indefinitely.Whichever view' may be ultimately Shown to be correct, it is certainly true that the extracorporeal sojourn of the typhoid germ is in¿uenced by certain factors, e. G., the nature of the food substances, the amount Of moisture, etc. The effect of these various factors has been repeatedly studied, and it may be presumed that, in a general way, their in¿uence is fairly well understood.There are, however, a number of factors whose in¿uence is more or less uncertain. Of these perhaps none is more important or Worthy of more careful consideration than the effect which various other bacteria have on the typhoid germ in their association with it.Bacteria in nature occur almost invariably in mixed cultures. Their association may be without effect on the various species, or it may affect them in various ways. They may offer mutual or onesided aid, and thus live in a symbiotic relation. They may, on the other hand, Offer mutual or one-sided injury, c., they may exert an antagonism on one another.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
