There are certain bacteria that are known to require many years of antibiotics to resolve: 1.) tuberculosis 2.) Leprosy (Mycobacterium leprae) For both of these it is normal to take antibiotics for many, many years. Also, less seriously, ordinary acne is often treated with antibiotics for years.

Some of the stories of long-term Lyme would suggest this. The 2 days of antibiotics for "prophylactic" protection makes sense only if the goal is to create antibiotic-resistant bacteria. 2 days of a relatively weak antibiotics is pure anti-science. She makes a good point here: "She also said the two-day course of doxycycline, often prescribed for people who find a tick embedded on their body, has little or no prophylactic value."
