Interpretive Summary: Biofilms are the sticky films present on the surfaces of poultry processing systems which are very similar to cooking surfaces that have not been cleaned in your home. They are very difficult to remove. In order to understand how these biofilms form, we looked at two genes responsible for the formation of the biofilm. Through our preliminary investigation, we were able to determine that the different kinds of Salmonella commonly associated with poultry use these genes differently. This could be important information because it may explain why some Salmonella are easier to clean off surfaces than others, and might lead to the development of new antimicrobials.
Technical Abstract: The formation of biofilms in poultry processing plants, especially as it relates to Salmonella contamination, can be a food safety concern. Salmonella enterica is one of the most prevalent and varied foodborne pathogens. The diversity in Salmonella serovar types results in the colonization of many types of hosts due to different environmental conditions and hazards. The aim of this study was to evaluate the differences in gene expression (bcsA and csgD) of Salmonella enterica serovars Heidelberg, Kentucky, and Enteritidis during biofilm formation using quantitative reverse-transcriptase polymerase chain reaction (qRT-PCR). Overall, there appeared to be differences in expression between the serovars with a high variation between strains. This data is important as it demonstrates considerable variability in gene expression between serovars and strains of poultry isolates of Salmonella enterica.
