Does neosporin make yeast infection worse?

Occlusion: Neosporin has antibacterial and no antifungal activity which can alter your skin / mucous membrane normal flora. Normal flora competes for space, food and binding sites with invaders. If the normal flora is wiped out the yeast can flourish. As well, the occlusive nature of the ointment can allow a warm moist environment for the yeast organisms...Making them happy campers.
