Why do antibodies work to kill bacteria but not viruses?
bacteria is complit cell or contain cellular material hence specific antibody riquar as compair to virus is difrance
Do antibiotics work against bacteria?
antibiotics are useful against bacteria because they help to kill off the nasty bacteria or they can also stop the bacteria from reproducing - so the illness doesn't get worse. this then gives your body time to make antibodies which will eventually distroy the bacteria. after this, you won't get the disease again because you are immune to it.
Antibodies work by attaching to the what making them useless?
Antibodies attach to antigens, which are foreign substances such as viruses or bacteria, to make them harmless by marking them for destruction by the immune system.
What are proteins that are made by cells to help destroy disease causing bacteria and viruses?
Antibodies are proteins produced by cells to target and destroy disease-causing bacteria and viruses in the body. They work by recognizing specific foreign invaders and signaling the immune system to attack and eliminate them.
What is the difference between and antiviral drug and an antibiotic drug?
No. Antivirals work to limit the reproduction of viruses, and antibiotics work to kill bacteria. Antivirals do not kill bacteria, and antibiotics do not kill viruses.
Why is it important to know whether your sore throat is cause by a virus or bacteria?
You have to know the cause to know how to treat it. There are specific treatments that kill bacteria, and others that block the activity of viruses. Practically none of them work against BOTH viruses and bacteria.
Why can you not kill flu with antibiotics?
Antibiotics are only for killing bacteria, they do not work on viruses which are the cause of the flu. Bacteria are living organisms and so poisons and chemicals can actually kill them. But flu viruses are non-living organisms so they can not be killed, they can only be inactivated by damage or physical blocking by antibodies (made by our immune systems) of the shapes of the structures viruses use to attach to a host's cells. Viruses need a host's cells to use to reproduce, if they can not attach to the cells, they will be inactivated. Antibiotics are not capable of inactivating them.
What pathogens respond to antibodies?
Pathogens such as bacteria, viruses, fungi, and parasites can respond to antibodies produced by the immune system. Antibodies work by binding to specific antigens on the surface of pathogens, marking them for destruction by other immune cells. This antibody response is a key component of the adaptive immune system's defense mechanism against infections.
How does the MMR vaccine work?
The MMR Vaccine contains tiny doses of living but inactivated viruses that cause measles, mumps and rubella. Once these viruses are injected into the body, the immune system will develop certain antibodies against these three diseases shortly following vaccination. Because your body has memory cells it now knows how to defeat these diseases when they enter the body again, and it will know which certain antibodies it needs to produce; these antibodies in your body will give a lifelong protection against these diseases.
Can azithromycin cure the flu?
No. Azithromycin is an antibiotic. Antibiotics only work to kill or control growth of bacteria. The flu is not caused by bacteria, so antibiotics are ineffective to treat it. Influenza is caused by viruses.
What are antibodies what do they do?
Antibodies are cells that help the immune system fight off virus and sometimes bacteria. Vaccines are created from the antibodies of viruses that host them. For example a flu vaccine is made of the antibodies of various flu viruses. With the exception of the Human Immunodeficiency Virus, or HIV, a typical virus only lasts only a couple of days and give off antibodies for your body to work with its white blood cells to fight infection. When a person becomes ill even with a mild cold your body immidiatly creates anti bodys from the white blood cells. This anti bodys mould themselvs around the bad bacteria and engulf it. the white blood cells then know that if the same bacteria returns it can be faught off straight away.
What simulates the body to produce chemicals that destroy viruses and bacteria?
The immune system simulates the body to produce chemicals such as antibodies, interferons, and cytokines that help destroy viruses and bacteria. These chemicals work together to identify and neutralize pathogens to protect the body from infections.
