AI Article Synopsis
- - The study assessed the biofilm formation ability of poultry isolates under various conditions, including different surfaces (stainless steel, polystyrene), temperatures (7, 25, and 42 °C), and oxygen levels (microaerophilic and aerobic).
- - All isolates successfully formed biofilm on both surfaces across the tested conditions, particularly thriving in dual-species scenarios where biofilm formation increased significantly at lower temperatures (7 °C).
- - Ten genes related to biofilm formation were identified in the isolates, with some detected across all samples, raising concerns about the ability of these poultry isolates to form resilient biofilms under diverse environments.
Article Abstract
The aims of this study were to evaluate the ability of isolated from a poultry slaughterhouse to form biofilm in the presence and absence of , and the effect of surface (stainless steel, polystyrene), temperature (7, 25, and 42 °C), and oxygen concentration (microaerophilic and aerobic conditions) on the formation of biofilm. The genes , , , , , , , , , , , and , related to biofilm formation by , were also investigated. All isolates formed biofilm on stainless steel and on polystyrene, in both aerobic and microaerophilic atmospheres, including temperatures not optimal for growth (7 and 25 °C), and biofilm also was formed in the presence of . In dual-species biofilm on stainless steel, biofilm formation was 2-6 log CFU·cm higher at 7 °C for all isolates, in comparison with monospecies biofilm. Ten genes (, , , , , , , , , and ) were detected in all isolates, but and were found in four and six isolates, respectively. The results obtained are of concern because the poultry isolates form biofilm in different conditions, which is enhanced in the presence of other biofilm formers, such as .
