POINTS TO CONSIDER:

Theory is that antibiotics kill the 'good' bacteria
which also prevents fungal growth.
This is why antibiotics are never given to fungal infections.
Although this is a theory, i can prove this theory right
by testing it on a measured growth of fungi.

Fungi are eukaryotic ( similar to human cells)
the mechanism for destroying the cells are different.

It is a known fact that antifungals kill all types of fungi .
E.g. yeasts to dermatophytes ( athletes foot)
So, it would be pointless to include antifungal cream or drops to
the dependent variable as it kill fungi the fastest.
