On the occurrence ofSalmonella bareilly in man and animals and the mode of transmission of the salmonellose caused by this species

In the Netherlands salmonellose due toS. bareilly was noted for the first time in 1948, initially only in man, but in the beginning of 1951 also in chicks. Between the end of March and the latter half of June the number of human cases has distinctly increased. Nine patients appeared to have had a recent contact with chicks which excretedS. bareilly or harboured this germ in their organs. The percentage of excreters of germs among chicks decreased after the first months. 481 eggs lain in autumn by young hens from poultry farms which had been found contaminated in spring 1951 did not containS. bareilly. Also a diseased person can spread the disease either by direct contact or by contaminating foodstuffs. In the course of our investigationS. bareilly has been incidentally cultivated from a rat and from material originating from a deer.
