An example of a nonspecific response to a pathogen is the inflammatory response. When tissues are injured or infected, they release chemicals that lead to blood vessel dilation and increased permeability, allowing immune cells to migrate to the affected area. This response helps contain and eliminate pathogens, regardless of their specific identity, and aims to initiate healing. Other nonspecific responses include fever and the action of phagocytic cells like macrophages that engulf and destroy invading microorganisms.
An example of a nonspecific internal response to harmful bacteria is inflammation. Inflammation is a general response triggered by the immune system to protect the body from foreign invaders. It involves increasing blood flow to the area, causing redness, swelling, and pain.
The inflammatory response is called a general defense because the response is similar regardless of the pathogen. It is a fundamental response of the body to injury and disease."Because the inflammatory response is the same no matter what the pathogen, it is called the body's general defense."

Nonspecific Defenses
Fever
A nonspecific response refers to the body's general defense mechanisms against pathogens that do not target a specific invader. This includes physical barriers like the skin, as well as immune responses such as inflammation and the action of phagocytes. These responses are activated quickly and aim to provide immediate protection, regardless of the type of pathogen encountered. Unlike specific immune responses, which are tailored to particular antigens, nonspecific responses are broad and act as the first line of defense in the immune system.

Antibodies do not play a role in the nonspecific immune response; they are part of the specific immune response, which targets specific pathogens. The nonspecific immune response relies on physical barriers (like skin), phagocytic cells, and other general defenses that act against a wide range of invaders without specificity. Substances like cytokines and complement proteins do contribute to the nonspecific immune response by enhancing inflammation and promoting the destruction of pathogens.
I'm having a bit of a problem accepting your nonspecific example.
Inflammation and fever are nonspecific immune system reactions.
