The testing method commonly used to diagnose E. coli O157:H7 is called culture-based isolation. In this method, a sample, typically from stool or food, is collected and cultured on specific media that promote the growth of E. coli bacteria, including E. coli O157:H7. The culture is then examined for the presence of characteristic colonies of E. coli O157:H7. Additionally, biochemical tests and serological methods may be employed to confirm the identity of the bacteria as E. coli O157:H7 and distinguish it from other strains of E. coli. This testing process allows healthcare professionals and public health authorities to accurately diagnose E. coli O157:H7 infections and take appropriate measures to treat affected individuals and prevent the spread of the bacteria.
