Phage inactivation of foodborne pathogens on cooked and raw meat

Phages infecting Salmonella Typhimurium PT160 and Campylobacter jejuni were added at a low or high (10 or 10 4) multiplicity of infection (MOI) to either low or high (5.9 log 10 cm −2 at 24 °C were achieved compared to phage-free controls using the Salmonella phage under optimal conditions (high hos...

description Phages infecting Salmonella Typhimurium PT160 and Campylobacter jejuni were added at a low or high (10 or 10 4) multiplicity of infection (MOI) to either low or high (5.9 log 10 cm −2 at 24 °C were achieved compared to phage-free controls using the Salmonella phage under optimal conditions (high host cell density and MOI). These results alongside those already published indicate that phages may be useful in the control for foodborne pathogens.
