mary mallon was treated unsuccessfully with antibiotics.

Explanation:

Mary Mallon, also known as Typhoid Mary, was a cook in the early 1900s, a carrier of Salmonella Typhi, and had no symptoms. Antibiotics were not widely available or used in the era when Mary Mallon was active (antibiotics like penicillin became prominent in the 1940s). So, she could not have been unsuccessfully treated with antibiotics.

Mary Mallon was treated unsuccessfully with antibiotics.
