A trial of biosecurity as a means to control Campylobacter infection of broiler chickens.
TL;DR: Analysis of infection at 42 days of age and over the life of the flock showed that the risk of thermophilic Campylobacter infection of broilers was reduced by over 50% in intervention flocks.

TL;DR: Data indicate that multiple antibiotic resistant (MAR)-like Campylobacter strains occur and it may be postulated that these may overexpress cmeABC or another efflux system.
Virulence of Salmonella enterica serotype Enteritidis aflagellate and afimbriate mutants in a day-old chick model
TL;DR: The data suggested that Enteritidis flagella, but not fimbriae, played an important role in pathogenesis in the chick model and that the flagellar apparatus itself and not motility per se contributed significantly to this role.

TL;DR: It is concluded that embryos are unlikely to carry BSE infectivity even if they have been collected at the end-stage of the disease, when the risk of maternal transmission is believed to be highest.

Surface Disinfection Tests with Salmonella and a Putative Indicator Bacterium, Mimicking Worst-Case Scenarios in Poultry Houses
TL;DR: Surface disinfection studies mimicking worst-case scenarios in badly cleaned poultry houses were made with 3 bacterial isolates, Salmonella enteritidis,Salmonella senftenberg, and Enterococcus faecalis, and a peroxygen compound, indicating its suitability as an indicator bacterium.
