DESCRIPTION:In 1994\, _Mycoplasma gallisepticum_\, a common bacterial path
 ogen of poultry\, jumped into house finches\, rapidly spreading through th
 eir entire eastern North American range and causing the death of millions.
  This emerging infectious disease outbreak is one of the best documented n
 atural epizootic to date and offers unique opportunities to test key quest
 ions regarding host shifting and host-pathogen co-evolution. Host resistan
 ce was found to have spread from standing genetic variation within 12 year
 s of disease exposure only\, and was associated with parallel changes in p
 athogen virulence. Here I discuss the phenotypic changes that took place o
 ver the course of the epizootic in both the host and the pathogen\, and sh
 ow that these phenotypic changes gave rise to significant increases in hos
 t and pathogen fitness\, as expected under an antagonistic co-evolution sc
 enario.
