Escherichia coli, turkey, cellulitis, microbiome


The term “microbiome” refers to all the micro-organisms within a particular environment. In poultry, the microbiome is influenced by the barn, diet, and age of the birds and is believed to modulate immunity and inflammation. In the past, culture methods were primarily used to evaluate the presence of the various micro-organisms present in the microbiome; however, recent technological advances in genomic sequencing have revolutionized sample analysis. This technology has opened new avenues of research in poultry production and our understanding of the associated health challenges. Turkey cellulitis has been a major economic and health concern for many years. Traditional bacterial culture methods indicate that multiple species may be involved in this disease with most studies implicating either Clostridium septicum or Clostridium perfringens as the primary pathogens. A recent study by Luisa de Oliveira et al. indicates that avian pathogenic Escherichia coli may also play an important role in the development of cellulitis. The purpose of this presentation is to share the results of a study conducted to further understand the microbiome of turkeys with cellulitis.
