Step by step
Solved in 2 steps
- While it is true that not all coliforms are pathogenic under normal conditions, please name two situations that can occur due to infection by pathogenic strains.Explain the difference between enterohemorrhagic, enterotoxigenic,enteroinvasive, enteropathogenic, enteroaggregative, anddiffusely adherent strains of E. coli.Compare the mechanism of virulence for Vibrio cholerae and enterotoxigenic E.coli. Specifically, how do these bacteria bind to host cells and what factors are involved in producing the diarrhea observed in infected patients?
