title: [Epizootic process caused by Salmonella species in broiler flocks].
abstract: As the result of vast epizootiologic studies for Salmonella infections in two broiler flocks the intensity of the apparent and the inapparent epizootic process was shown to grow over the period of fattening. Statistical methods, such as Shovene's criterion and the correlation analysis were made use of in the interpretation of the results. The importance was ascertained (in epizootic aspect) of the lack of harmlessness of the technology employed in terms of the transmission of Salmonella organisms. It was demonstrated that from the very beginning of introducing the batches up to the end of the fattening period a predominantly inapparent epizootic process ran its course, caused by several Salmonella species.
