Serologic Associations between Fowl Cholera and Other Diseases

Abstract

As part of a case-control study designed to identify fowl cholera risk factors, 2087 blood samples were collected from 71 California meat-turkey flocks. Samples were tested for antibodies to three mycoplasmas and four viruses pathogenic for turkeys. Flocks that had antibodies to Newcastle disease virus and/or Mycoplasma meleagridis had an increased risk of having an outbreak of fowl cholera. This information should prove useful for fowl cholera control programs in meat turkeys.
