Answer:
Bacteriophage
Explanation:
Antimicrobial resistance is the leading world concern for the medicine producing companies. The antimicrobial drugs are meant to kill the microbes but microbes are also developing resistant to these drugs. So we need a high dose of that particular drug to kill the same organism next time. The antimicrobial medicines are applied to all microorganism without distinguishing them but bacteriophage is emerging as solution for the problem.
Bacteriophages are viruses that attack the bacteria. Bacteriophages are highly specific to bacterial cell and attack the receptors on the membrane of specific bacteria species. So these can be used to kill or target the specific species of bacteria instead of applying the antimicrobial drug to all bacteria.
That would be Sternum as it is also called the "breastbone".
It is not easily recognizable
