Since molds don't have an immune system, they produce antibiodics that kill bacteria.
Antibiotics not only kill bad bacteria, they kill good bacteria, antibotics cannot know the difference, killing the good bacteria hurts the immune system.
To kill E.coli, antibiotics destroy its molecular coating, which allows the body's immune system to kill the bacteria.
They have enzymes in them to kill pathogens
People fall sick because of the 'bad' bacteria which infest our bodies. These may spread through coughing, sneezing, etc. Our body has a special system called the 'Immune System'. Just like other organ systems, it has a function, a job to kill all the bad bacteria. Sometimes, it needs to identify the bacteria so the immunity shots we take contains a very weak bacteria of that type to help the immune system recognise the bacteria. Once we get our shot, our immune system recognises the bacteria and starts killing any other which come. This makes us immune to the bacteria or disease.But sometimes we need to take the other medicines, as the bacteria is producing more very fast, too fast for our immune system to kill all of them. That's why we have the antibiotics, etc. And not all shots are the ones like above, only some are the ones for recognition of the bacteria.
they work together and fight off EVIL bacteria They Kill Bacteria
Macrophages are the large irregularly shaped cells that kill bacteria by digesting them through a process called phagocytosis. These immune cells play a crucial role in the body's defense against pathogens.
Vaccines are given because they keep you from getting sick. They work by preparing your immune system to fight bacteria by themselves. A dead, or weak, strain of the bacteria is given to the body. Your immune system can then produce anti bodies to kill them. Your system can then remember how it did it. If you should get a virrulent strain in future, an effecient attack can then be launched automatically.
When antibiotics kill M. leprae, antigens (the proteins on the surface of the organism that initiate the body's immune system response) are released from the dying bacteria.
Bacteria that enter the body can be destroyed by the immune system through mechanisms like white blood cells, antibodies, and inflammation. The immune response works to identify and attack the invading bacteria to prevent infection and illness. Antibiotics can also be used to kill bacteria directly in certain infections.
It's the opposite. Penicillin is given to a patient to Kill. Actually, to kill the harmful bacteria. The bad part about taking penicillin is it also kills good bacteria that are in your digestive system. When the harmful bacteria is minimized by the penicillin, your body's immune system is able to fight off the infection and heal itself.
Consider the following scenario: An antibiotic is applied to a petri dish of bacteria. The antibiotic will kill of most of the bacteria, but some will remain that are immune to the antibiotic. Therefore, only the immune bacteria will reproduce. Soon, the whole petri dish will be full of bacteria that is immune to the antibiotic. Nature "selects" the immune bacteria for survival.
