I want to know the answer to the following question:
Bacterial infections could be treated with medicines containing what kind of dye?
All the background I'm provided with is that "Arsphenamine proved to be the first effective treatment for syphilis, a disease which prior to that time was incurable and led inexorably to severe skin ulceration, neurological damage, and death.[citation needed]". Is that enough to answer the question?
Answer: no
