Empleo de bacteriófagos frente a Salmonella enteritidis como herramienta de prevención

Introduction: salmonellosis is a highly prevalent disease still searching for preventive tools to avoid contamination level priority public health. Objective: the in vitro effect of bacteriophages against Salmonella enteritidis was evaluated as a prevention tool. Method: two tests with three concentrations of bacteriophages were conducted against two strains of Salmonella Enteritidis inoculated in fresh faeces of laying hens. Each test had a positive control. Thus, four groups in each test were evaluated. Each experimental group included two replicates, and three plates were incubated per replicate. The concentrations tested were three: commercial solution (5 × 10 7
