Selective toxicity is a trait which is present in almost all anti-infective agents. This trait allows anti-infective agents to affect and target particular enzymes and proteins in antigens.
Selective toxicity is a trait which is responsible for effecting certain proteins, enzymes or structures in infectious agents like bacteria, fungi and viruses. Without this trait the anti-infectious agents or drugs would have a toxic affect that would be exerted on not only antigens but also on normal, unharmed cells in the body of the host organism. Selective toxicity is displayed by most antibiotics, where these drugs affect the bacterial cell wall and its components. This is also displayed by antiviral drugs. these antiviral drugs affect the spike proteins or capsid proteins on the virus. Antivirals can also be selectively toxic towards receptors that are the point of attachment towards viruses.
