Definition: Antispasis is a medical term referring to the condition in which an immune system attacks or destroys tissues, cells, or organs that are believed to be damaged or infected by viruses, bacteria, fungi, parasites, or other pathogens. The process can occur due to various conditions such as infections, autoimmune disorders, or genetic defects. In this context, antispasis typically means a lack of infection or disease, preventing the body from responding appropriately to the attack.
