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.
Can a parasite be a pathogen?
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.
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 is a type of microbial pathogen that invade cells and destroys them?
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 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 type of host must be available and capable of being infected by a pathogen in order for infection to take place?
For an infection to occur, a susceptible host must be present, meaning that the host's immune system is either compromised or not fully equipped to combat the pathogen. This often includes individuals with weakened immune responses, such as those with chronic illnesses, the elderly, or young children. Additionally, the host must have specific receptors or cellular environments that allow the pathogen to attach, invade, and replicate. Without these conditions, the pathogen is unlikely to establish an infection.
Why does my 1999 Ford Expedition smell like antifreeze inside the car?
Your heater core may have a leak in it, allowing the fumes to invade the inside of the vehicle.
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.
Which words have a prefix that means in on or into?
Some words with a prefix that means "in, on, or into" include: include, inside, involve, invade.
How do pathogen increase pathogen virulence?
Pathogens can increase their virulence through genetic mutations, acquisition of new virulence factors, suppression of host immune responses, or improved adaptation to host environment. This may result in enhanced ability to invade host tissues, evade immune detection, or cause more severe disease.
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.
Is cancer a disease of cell division?
Partially yes. Cancer is a disease of population of cells that live, divide, invade and srepad without normal control.
