Toxins
Some pathogens produce toxins.
Toxins.
Plants produce antimicrobial compounds and have physical barriers like cell walls to resist pathogens. Animals have immune systems that produce antibodies and cells that can recognize and eliminate pathogens through various mechanisms such as phagocytosis and inflammation.
Pathogens
Some are, some aren't. Parasites are pathogens and can be quite large in some cases.
Not always. Pathogens such as viruses must attack human cells to replicate. Other pathogens like bacteria can actually attack and distroy tissue or just cling onto the surface. (For example: Clostridium Difficile is a bacteria that can grow out of control in a person's colon; they cling to the walls and prevent the absorption of fluids, this results in diarrhea.) Some bacteria produce toxins that attack tissues.Yes some pathogens attack human tissue.Yes
Yes, pathogens are agents capable of causing infections or some types of diseases. Pathogens are normally on our skin and any objects without causing problems. Not all pathogens succeed in their goal to find a host, but many pathogens do.
B cells are the cells that produce antibodies, which are proteins that can neutralize pathogens. Natural killer (NK) cells are a type of lymphocyte that can directly destroy infected cells and cancer cells.
There are three major non-adaptive or innate defenses in the skin to prevent the entry of pathogenic organisms.Keratin acts as a physical barrier to prevent moisture from escaping and pathogens from entering.Sebaceous glands in the skin produce sebum which is an oily substance that can inhibit the growth of some bacteria.Epithelial cells produce antimicrobial peptides called defensins.
A pathogen is any microorganism (such as a virus or bacterium) that causes disease. And this dick In your mouth
The process of immunity is to produce specific antibodies that bind to antigens on the surface of pathogens. =]
