B cells and Helper T cells
T cells
The molecules on pathogens that enable the immune system to distinguish one kind of pathogen from another are called antigens. Antibodies destroy pathogens by binding to the antigens on the pathogen.
Cells that identify pathogens and distinguish one from another are called antigen-presenting cells (APCs), such as dendritic cells, macrophages, and B cells. These cells play a key role in activating the immune response by presenting antigens to other immune cells, like T cells, to initiate a targeted immune response against the specific pathogen.
Another word for identify is "recognize" or "determine".
Distinguish or pinpoint
Parasite is an organism, that lives off another organism. Pathogen is something that causes disease in another organism. So the answer is "Yes". eg Malaria is a disease caused by a parasite.
Primary Pathogens are the microorganisms that cause diseases in healthy individual. Opportunistic Pathogens are the microorganisms that are ordinarily in contact with the host and cause disease when the host's resistance is low.
When pathogens are transferred from one surface to another, they can potentially contaminate the new surface, leading to the risk of infection if a person comes into contact with it. This transfer can occur through direct touch, airborne particles, or contaminated objects. The viability of the pathogens depends on factors such as the type of pathogen, the surface material, and environmental conditions. Effective cleaning and disinfection practices are essential to mitigate the spread of these pathogens.
Cells of the immune system, such as T cells and B cells, play a crucial role in identifying and distinguishing pathogens. T cells recognize specific antigens presented by infected cells and trigger an immune response, while B cells produce antibodies that bind to antigens on pathogens, marking them for destruction by other immune cells. This process allows the immune system to target and eliminate a wide variety of pathogens efficiently.
Our immune systems are designed to keep track of the various infections that can be caused by pathogens once they encounter them. This helps to increase our immunity as this information helps the bodies immune system to fortify itself against further attacks by the same pathogen. If immunity is increased by means other than acquiring the disease, then it is known as passive immunity. e.g. Vaccination( in this weak pathogens are injected in the body and this helps the body's immune system to remember and then identify it to fortify the body for any future attacks by that pathogen)
Pathogen
An infectious agent is a pathogen (germ). There are six kinds of infectious agents.Here they are listed:BactiriaVirusFungiHelminthPrionProtizoa.
