New antibiotic candidate identified in human body
Scientists have identified a new antibiotic candidate in the human body that would help in developing new drugs that can be used against drug-resistant bacteria.

Key Points:
i. Researchers from the MIT and the University of Naples Federico II in Italy have found that fragments of the protein pepsinogen used to digest food in the stomach, can kill bacteria like Salmonella and E. coli.
ii. Pepsinogen breaks down proteins in food. Hydrochloric acid is secreted by the cells lining the stomach.
iii. Hydrochloric acid mixes with pepsinogen and converts it into pepsin A that digests proteins, and into various other small fragments.
iv. Earlier the functions of these fragments were unknown. Now, it has been found that these fragments work as antimicrobial candidates.
v. A study regarding this has been published in the journal ACS Synthetic Biology.
vi. Three pepsinogen fragments were tested against a skin infection in mice. It was found that the peptides reduced the infections.
vii. Researchers have planned to modify these peptides to use them as antibiotics.
