Penicillin was discovered in 1928 and used as an antibiotic soon after that. However, it does not work against all bacterial infections. Since then, hundreds of different antibiotics have been developed to counter different bacterial infections. There are several guidebooks for a physician to choose the right antibiotic or antimicrobial drug for a patient. However, very few apps exist that can guide the physician to the most appropriate antibiotic for any given case. The goal is to turn the guidelines into a user-friendly App for a mobile device.
