Part 1
If the bactria from Fabrice’s lesion were gram stained, the spirochete would appear which colour
Answer Pink
Because The structural design of the spirochete cell wall is like to that of gram negative bacteria, it contains a peptidoglycan layer sandwiched between lipid inner and outer membranes. As gram-negative bacteria have a thinner layer so do not retain the purple stain and are counter-stained pink by safranin.
So Pink Colour
Part 2
Would it be possible for someone with yaws to infect someone else and cause syphilis
Answer: No because different subspecies of Treponema pallidum cause these two diseases.
Yaws is transmitted by direct contact with the skin sores of infected people. The causative organism of Yaws is a bacterium viz. Treponema pertenue, a subspecies of Treponema pallidum that causes venereal syphilis. Syphilis is a sexually transmitted infection. T. pallidum manifests in different ways depending on environmental conditions and other factors.
