Case Study of Mycin
MYCIN was an early backward chaining expert system that used artificial intelligence to identify bacteria causing severe infections, such as bacteremia and meningitis , and to recommend antibiotics , with the dosage adjusted for patient's body weight — the name derived from the antibiotics themselves, as many antibiotics have the suffix "-mycin". The Mycin system was also used for the diagnosis of blood clotting diseases. It was written in Lisp as the doctoral dissertation of Edward Shortliffe under the direction of Bruce G. Buchanan, Stanley N.

The program could request further information concerning the patient, as well as suggest additional laboratory tests, to arrive at a probable diagnosis , after which it would recommend a course of treatment.
