Bachelor of Medicine and Bachelor of Surgery, or in Latin Medicinae Baccalaureus et Baccalaureus Chirurgiae (abbreviated MB BChir, MB BCh, MB ChB, BM BS, MB BS etc.), are the two degrees awarded after a course of undergraduate study in medicine and surgery at a university in the United Kingdom and other places following the same convention. This includes medical schools in India, Australia, Egypt, Hong Kong (People's Republic of China), Iraq, Kuwait, Malaysia, Guyana, Singapore, Libya, Republic of China (Taiwan), Malawi, Mauritius, Bangladesh, Barbados, Fiji, Ghana, Myanmar, Jordan, Iraq, Nepal, New Zealand, Jamaica, Papua New Guinea, South Africa, Nigeria, Saudi Arabia, Sierra Leone, Sri Lanka, Sudan, Pakistan, Samoa, Tanzania, Trinidad and Tobago, United Arab Emirates, Zambia and Zimbabwe. blank">http://www.ecfmg.org/creds/refgde.html The naming suggests that they are two separate degrees; however, in practice, they are usually treated as one. (At Oxford and Cambridge it is/was possible to be awarded the two degrees on different dates.)

Those holding the degree(s) and practising medicine are usually referred to as "Doctor" and use the prefix "Dr".

The degrees are often used as the Commonwealth equivalent of what is known elsewhere as the degree of _Doctor of Medicine (MD). http://www.umassmed.edu/faculty/show.cfm?start=0&faculty=682 In countries that award bachelors' degrees in medicine, however, the MD refers to a Higher Doctorate, and is reserved for medical practitioners who do research and submit a thesis in the field of medicine.

Because they are considered equivalent allopathic medical degrees, in the United States each state board of medicine allows those who have been granted a "bachelor of medicine" overseas the right to use the title "MD" while practicing in the United States.
