Why might Candida albicans become pathogenic in an individual receiving antibacterial medications?
A. This fungal organism can actually utilize the destroyed bacterial cells as a nutrient source and begin to multiply out of control. This can cause a pathogenic state. B. This is an opportunistic pathogen not normally found in normal microbiota. As such, when the bacterial normal microbiota is wiped out by broad-spectrum antibacterial drugs, this opportunist can adhere to and colonize the area left behind. C. This is a usual member of the normal microbiota. However, when the bacterial members of the normal microbiota are wiped out by a broad-spectrum antibacterial drug, this fungal cell type has little to no competition for resources in the affected area. As such, it quickly overgrows and can cause a pathogenic state. D. This is a protozoan species and part of the normal microbiota. When the bacterial members of the normal microbiota are wiped out by a broad-spectrum antibacterial drug, this protozoan cell type has little to no competition for resources in the affected area.
