Bartonella species, disease expression and host immunity

1.0 CME. This module provides an overview of the major factors that influence disease expression resulting from Bartonella spp infection with particular attention to bacterial infection strategies and the histopathological progression of lesions observed in both immunocompetent and severely immunodeficient patients.

This module provides an overview of the major factors that influence disease expression resulting from Bartonella spp infection with particular attention to bacterial infection strategies and the histopathological progression of lesions observed in both immunocompetent and severely immunodeficient patients.

Learning objectives:

  1. List the major factors that influence disease expression after infection with a Bartonella species
  2. List the strategies of frontal versus stealth pathogens
  3. Describe the histopathological progression of lesions in individuals ranging from immunocompetence to severe immunodeficiency
