Escherichia coli is the most widely studied bacterium over the world. It iswell-known that E. coli is the predominant non-pathogenic microbiota ofwarm blood species; however, some strains have developed the ability tocause severe diseases. Taking into account the diversity in American countries,this chapter examines the complex situation of puzzling intestinalpathogenic E. coli, also called diarrheagenic, (enteropathogenic E. coli, Shigatoxin-producing E. coli, enterotoxigenic E. coli, enteroaggregative E. coli,enteroinvasive E. coli, diffusely adherent E. coli), and extra-intestinal E. coli(uropathogenic E. coli, neonatal meningitis-associated E. coli, avian pathogenicE. coli, sepsis-associated E. coli, mammary pathogenic E. coli, endometrialpathogenic E. coli, and necrotoxigenic E. coli) in animals. In additionto E. coli-associated animal diseases, the role of carriers and reservoirs ispresented, including the last regional references from synanthropic and wildanimals. Findings of the last 5 years are discussed and data of the eco-epidemiology of E. coli is also included. Considering the concept of OneHealth, which recognizes that health of humans is connected to health of animalsand the environment, the strategies to diminish illness in human populationcannot exclude control and vigilance of pathogenic strains in animals.However, in E. coli control, strategies distinguish between those strains thatproduce animal illness and those that affect humans and have an animal reservoir.The different proposed ways to E. coli control are also discussed.
