Uptake and persistence of Salmonella isolates from wild birds in avian HD11 cells. Viable counts of a sub-sample of Salmonella enterica serovar Typhimurium isolates, plus an isolate that could not be characterised by serotyping, expressed as CFU/ml were determined on nutrient agar after the ability of the isolates to invade and persist in avian HD11 cells was assessed using a gentamicin protection assay. Within the sub-sample there were isolates of each phage type and S. Typhimurium pulsed field group identified in this study (a – f) plus two control strains (F98 and SL1344).
