Dear dheeraj,

In BSc you can go for biotechnology, microbiology, botany etc.

Essential Information. Medical microbiology is a field of scientific study that includes looking at bacteria, viruses, and parasites in connection with disease and illness. Degrees can be obtained at the bachelor's, master's, doctoral and post-doctorate levels, leading to a variety of career paths.

In India scope of biotechnology and medical microbiology that after bsc to be honest there is no hope of any core jobs you can go for sales job.

After bsc you can also to .MSc in same field or you change field too. 

To be honest there is not so much scope of biotechnology and microbiology as compared to abroad. 

I hope I have cleared you doubt.
