1) All of these
2) eye
3) heart
4) CNS
5) bone

Answer 1

During the tertiary stage of syphilis, caused by Treponema pallidum, the bacterium may attack the eye, heart, central nervous system, and bones, leading to severe complications including paralysis and dementia.

Step-by-step explanation:

The causative agent of syphilis may attack several body parts during the tertiary stage of the disease. This occurs 10 to 20 years after the initial infection. In this stage, the Treponema pallidum bacterium can lead to serious health problems, including gummas, which are granulomatous lesions that may appear in various locations such as the bones, mucous membranes, and internal organs. Of the options provided, tertiary syphilis may attack all the listed parts: the eye, heart, central nervous system (CNS), and bone. Tertiary syphilis can cause severe damage such as blindness, heart problems, neurological issues including dementia and paralysis, and damage to the skeletal system.
