Survival of Co-Cultured with spp. in Aerobic Conditions.

and are responsible for the two major foodborne zoonotic diseases in Europe; poultry is the main infection source. cannot grow under aerobic conditions, but can show aerobic survival when co-cultured with other microorganisms; however, its interaction with has not been studied yet. In this study, these two bacteria were co-cultured under controlled aerobic conditions. Different concentrations and strains of were incubated with or without different serotypes (10 CFU) at 37 °C for 16 h. did not grow after incubation with or without . The survival of was observed only for the highest initial concentration of 6 log CFU/mL with or without . However, its survival was significantly higher when co-cultured with . No survival was observed at lower concentrations. survival was positively affected by the presence of but depended on the serotype, the strain and the initial concentration. On the other hand, the enumerations were not affected by . Our results suggest potential interactions between and that require further investigations for a clearer understanding of their behavior in natural habitats.
