The Bacteriophage-Content of Chicken-Droppings and the Influence of Feeding of Dysentery Bacteria on the Origin of Bacteriophages
Abstract
The phage-content of chicken feces is extremely variable and in each test exhibits a different form. The irregularity in the occurrence of the phages is so great that even two immediately successive discharges show a different phage-content. It is immaterial whether a large or small amount of feces is used. The results in both cases remain the same. During the coarse of many tests one can be certain of finding phages in the feces of chickens against almost any kind of dysentery-germ. Many phages recur very irregularly and disappear rapidly. Others are very common and in almost every test can be found without difficulty. The artificial infection of chickens with dysentery-bacteria does not lead to the arising of homologous phages. When the phages for certain dysentery bacteria do occur along with those bacteria, the occurrence is so irregular that we cannot draw a causal-relationship or correlation of the two. We observed in two cases the first occurrence of a particular phage immediately preceding the feeding of the bacteria concerned. The phage, however, was again missing after the feeding of the bacteria.
