greetings,

There seems to be some misunderstanding, I suppose? MBA is a masters course in business administration and there is no such branch as microbiology in the specialization subjects available.

Some of the common and popular MBA branches are

- Marketing

- Finance

- Human Resource management

I am attaching a link to more info on the MBA exam and please get back to me through a comment if you have some information about an MBA degree in microbiology.
