Positive biofilms to control surface-associated microbial communities in a broiler chicken production system

In this study, the inner surfaces of commercial broiler chicken houses were treated or not after cleaning and disinfection procedures with a bacterial consortium composed of Bacillus spp. and Pediococcus strains, able to form covering biofilms in different laboratory models. Preinstalled coupons were sampled over time to capture microbial biofilm dynamics on farm surface. The results showed that the bacterial consortium is able to establish on the farm surfaces, to modulate microbial communities and to limit the implantation of Enterobacteriaceae and Enterococcaceae, two families containing potential pathogens.
