Answer:

1. The discovery of penicillin changed the course of modern medicine significantly, because due to penicillin infections that were previously untreatable and life threatening were now easily treated.

2. World War II saw major advances in medical technology including the mass production of penicillin. On March 14, 1942, U.S. made-penicillin was used to successfully treat the first patient for septicemia, or blood poisoning

3. One of the biggest reasons the pharma industry is not interested in antibiotic drug development is that it is an extremely costly venture. According to estimates, the cost of developing an antibiotic is around $1.5 billion

4.Misuse and overuse of antimicrobials are the main drivers in the development of drug-resistant pathogens. Lack of clean water and sanitation and inadequate infection prevention and control promotes the spread of microbes, some of which can be resistant to antimicrobial treatment

5. A growing number of infections – such as pneumonia, tuberculosis, gonorrhoea, and salmonellosis – are becoming harder to treat as the antibiotics used to treat them become less effective. Antibiotic resistance leads to longer hospital stays, higher medical costs and increased mortality

Step-by-step explanation:

i hope this helps :)
