Why do scientists have to find a new antibiotic to kill bacteria?
Wiki User

After releasing enough of one type of antibiotic onto some bacteria, given enough time the bacteria will adapt, and even change to be unaffected by the given antibiotic. The only way to inhibit the bacteria then is find a new, better antibiotic, after which, given enough time and exposure, the bacteria will get used to this antibiotic, so there is again a need for a new one.

What is work of antibiotic?
Antibiotics are used to kill bacteria.
What is antibiotic resistant bacteria?
Also known as "superbugs", antibiotic resistant bacteria have evolved to a point that our usual antibiotics won't kill them. VRE and MRSA are common forms of antibiotic resistant bacteria.
What fungus produces a substance that can kill bacteria?
One fungus that produces an antibiotic and will kill some bacteria is Penicillium.
What is an antibiotic used since the 1940s to kill bacteria?
Penecilin
What is a chemical that can kill bacteria with out harming the human body?
antibiotic
Can ciprofloxacin 500 kill internal parasites worms?

Explain how natural selection can give rive to a population of antibiotic resistant bacteria?
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.
Does triple antibiotic cream cure ringworm?
No, ringworm is a fungus not a bacteria. It needs to be treated with a fungicidal. In fact, there is a small chance using triple antibiotic cream may make it worse since antibiotic creams are usually made to kill bacteria only. If you kill all the bacteria in the area, it may kill the fungus's (ringworm) competition and allow it to flourish.
What is an enzyme that is also an antibiotic that kill disease-causing bacteria?
Enzyme Inhibitors
Does paracetamol kill bacteria in the body?
No it does not kill bacteria as it is not antibiotic. It is used as antipyretic and analgesic for pain relief as in common cold headache and mild fever
Why is there not a cure for salmonella?
The trick with curing a bacterial infection is to find something that will kill that particular type of bacteria, but which will not kill human cells. Since the biochemistry of human cells is very similar to that of bacteria, most of the things that kill bacteria will also kill human cells. You do not want to cure a disease at the expense of killing the patient. So, there is no guarantee that such cures can be found. You can do research into various antibiotics, but you may or may not find something that works. Furthermore, even when you do find a good antibiotic, bacteria tend to evolve resistant strains which can no longer be killed by that particular antibiotic. Bacteria are very tough, adaptable organisms. Do not underestimate them.
What antibiotic will kill fungus in humans?
No antibiotics will kill fungi living anywhere. Antibiotics either kill or stop bacteria reproducing.
