Answer 1

9. The EPEC (Enteropathogenic Escherichia coli) and EIEC (Enteroinvasive Escherichia coli) can be distinguished from each other by their antigenic structure. EPEC has a specific antigenic structure called the "Lambert" antigen, while EIEC has a different antigenic structure.10. The virulence factors of V. cholerae include:1. Cholerogen-toxin2. Cholera toxin11. For diagnosing bacterial dysentery, the specimens that can be examined are:4. Stool12. The culture media used for Mycobacterium tuberculosis isolation are:4. Lewenstein-Jensen medium13. The cultural properties of Bordetella pertussis are characterized by:2. They are strict aerobes
