Pneumonia caused by the bacterium Rhodococcus equi is an important cause of disease and death in foals worldwide. Despite over a century of efforts, an effect vaccine for this disease is lacking. To date, the only effective approach to immunization has been gavage with live, virulent R. equi. Current knowledge of this method of immunization and how the gut might be mediating immunity in the lungs will be reviewed with an emphasis on ongoing research.

Learning Objectives:

  • Upon completion, participants will become informed of the evidence for the gut-lung axis in mediating immunity to pneumonia caused by Rhodococcus equi.
  • Upon completion, participants will understand key knowledge gaps in the mechanistic basis of lung immunity induced by enteral exposure to virulent Rhodococcus equi.
  • Upon completion, participants will gain understanding of potential mechanisms for how enteral immunization of foals might induce pulmonary immunity to Rhodococcus equi.
