Gram-negative, aerobic, enteric pathogens among intestinal microflora of wild turkey vultures (Cathartes aura) in west central Texas.

The prevalence of gram-negative bacterial species in the intestines of 20 apparently healthy turkey vultures (Cathartes aura) was determined. Edwardsiella tarda, Plesiomonas shigelloides, Salmonella, and Arizona hinshawii (Salmonella arizonae) were each recovered from 15% of these birds. Turkey vultures may be important reservoirs of these bacterial pathogens.
