Syphilis is caused by Treponema pallidum, a spirochete bacterium that cannot be cultured on standard artificial cell-free agar media. 2. The Schick test is an intradermal skin test used to determine whether a person has sufficient protective antibodies against the diphtheria toxin. 3. Diphtheria toxin, produced by lysogenized strains of Corynebacterium diphtheriae, inhibits eukaryotic protein synthesis by inactivating Elongation Factor-2 (EF-2). Which of the statements given above are correct?
