Epidemiological aspects of Salmonella infantis and Salmonella typhi murium infections in Finnish broiler chickens.

In this paper salmonella infections in Finnish broilers have been described. Especially infections detected in the farms of company A have been studied. Attention has been paid to the year by year continuing numerous S. infantis infections. In agreement with earlier reports, there is some evidence suggesting that a hatchery might have spread the infections. The examination of grandparent and parent birds as well as hatcheries with respect to salmonella infections should be more thorough and clear. It is, for example, for the moment not known at the farms of company A from which parent bird flocks the chickens come. This knowledge should be very important when the origin of salmonella infections is tried to be clarified.
