A type of microbial pathogen that invades and destroys host cells is a virus. Viruses, such as the influenza virus or HIV, penetrate host cells and hijack their machinery to replicate, ultimately leading to cell death. This destruction can trigger immune responses, contributing to the symptoms of viral infections. Other examples include certain bacteria, like Listeria, which can also invade and lyse host cells.
What else can I help you with?
Once the body encounters a pathogen and destroys it what is created?
Once the body activated, killer T cells it recognize pathogen and destroy them. In response that will create memory B cells and T cells specific to a certain pathogen, so if it ever came back it will be killed immediately.
What happens after a white blood cell destroys a pathogen?
After a white blood cell destroys a pathogen, it can either die itself or continue circulating in the body to fight other pathogens. The debris from the destroyed pathogen is usually broken down and eliminated from the body through processes such as phagocytosis or excretion.
Is HIV a bloodborne pathogen?
Yes, it primarily exists in the circulatory system and destroys T-cells. This is why blood transfusions are checked for HIV/AIDS.
What is on kind of microbe that attacks body cells called?
A microbe that attacks body cells is called a pathogen. Pathogens can include viruses, bacteria, fungi, and parasites that invade host cells and cause diseases.
What is the difference between plasma cells and memory cells of B-lymphocyte?
Both are B-cells but plasma cells are the B-cells which acted on the pathogen the first time they invade the body while the memory cells are the B-lymphocytes that act on the antigen(pathogen) the second time it invades and when ever it invades the body again.Memory cells are much faster than plasma cells though plasma cells act very quickly on the pathogen once detected. but until it gets detected it needs time.Memory cells will work as soon as the pathogen enters the body before the person could even feel the symptoms.
What does the pathogen attack?
The pathogen attacks specific host cells or tissues, depending on its type. For example, bacteria can invade and multiply within tissues, while viruses typically hijack host cells to replicate themselves. Fungi can invade skin or internal organs, and parasites may target various systems in the host. The result is often inflammation and damage to the affected areas, leading to disease symptoms.
What occurs when pathogens invade the body and what is the response of the body to the invasion?
It depends what sort of pathogen it is and what cells are infected but in general the infected cell is destroyed by lymphocytes and then engulfed by a phagocyte to get rid of what is left.
What are exoenzymes from pathogens?
Exoenzymes are digestive enzymes that are secreted by the pathogen into the surrounding tissues, allowing the pathogen to further invade the host's tissues. For example, Streptococcus pyogenes secretes streptokinase to dissolve blood clots, allowing wound invasion, and streptolysin, which digests red blood cells and other body cells. Clostridium perfringens, an agent of gangrene, secretes a lipase that damages cell membranes, creating more dead tissue for these bacteria to invade.
What steps happen when a lymphocyte recognizes a pathogen?
When a lymphocyte recognizes a pathogen, it first binds to specific antigens on the pathogen's surface through its unique receptors. This recognition activates the lymphocyte, leading to its proliferation and differentiation into effector cells, such as cytotoxic T cells or antibody-secreting B cells. These effector cells work to eliminate the pathogen, either by directly killing infected cells or by producing antibodies that neutralize the pathogen. Additionally, memory cells are formed to provide long-term immunity against future infections by the same pathogen.
What destroys body cells that are infected with a pathogen?
It depends on the pathogen. If it is a virus, the virus will replicate (reproduce its DNA) inside the cell (known as a host cell). The virus clones will then leave the cell and in doing so, cause the cell to die. When this happens many many times, lot of the cells of a tissue die and the tissue itself will start to fail. If it is a bacteria, the bacteria release toxins (endotoxins) which kill the cells directly (from outside).
What recognizes a pathogen?
t cells
Which pathogen is not made of cells?
A virus.
