Dear Shariqa, for being eligible for M.Sc Microbiology a candidate must have a Bachelor's degree from a recognised University with 2 subjects in a combination of home science, human genetics, botany, zoology, biochemistry, biotechnology, plant protection, microbiology, dairy sciences, agriculture and horticulture, fisheries and public health from a recognised University. Unfortunately B.Sc in Chemistry is not deemed eligible. However, there might be open universities which are ok with graduation in any stream. Do let us know if you want us to check that information for you.
