Do all antibiotics have the same mechanism for killing bacteria?

They have different mechanisms but some of them are almost similar. The main difference among antibiotics is that everyone is developed to fight different types of bacteria, aiming different organs as well.

Are antibiotics helping your body?
Yes. Antibiotics help by killing off invading bacteria. Your body is probably trying to do the same thing, but anitbiotics may make this happen faster.
Can you use antibiotics and painkiller same time?
Yes. They do not work at the same site nor by the same mechanism.
Why can antibiotics treat flu-like symptoms caused by bacteria but are ineffective against flu?
Because the way antibiotics treat those symptoms is by killing the bacteria that cause them. If the symptoms are caused by viruses, then antibiotics can't help since they are not made to be able to "kill" viruses, just bacteria. Flu viruses are not really living organisms like bacteria are. So viruses must be inactivated rather than killed. Antibiotics can neither kill nor inactivate viruses. They are created to be used to kill only specific bacteria, they do not kill every kind of bacteria, either. That is why there are so many different kinds of antibiotics. Antibiotics can treat flu-like symptoms caused by some bacteria, because the right antibiotics can kill bacteria. So although flu like symptoms are similar to those of the flu, they are caused by different microbes so are not cured in the same way.
Are Avelox and Bactrim the same type of medicine?
They're both antibiotics, but they don't kill the same bacteria.
What are antibiotics and what are they used for?
Antibiotics are medicines that cure infections. They have no effect on viruses.
How do you interpret the results when you apply two different antibiotics to two bacteria samples and they grew at the same pace?
If you apply two different antibiotics to two bacteria samples and they grew at the same pace, those antibiotics are equally effective or ineffective. Depending on the rate of growth, they may be unsuitable for use in treating an infection with that bacterium.
Could mutated bacteria be resistant to antibiotics?
Yes. The flu strand of bacteria, for example, is always mutating into different forms, becoming immune to the same kind of anitbiotics. Therefore, different antibiotics are used all of the time.
Why cant antibiotics be used to treat diseases like flu or HIV?
Antibiotics are used for bacteria, HIV and FLU are a type of viris, not a bacteriumyou would have to use anti-viral tablets but they are not very effective because they can destroy your cells (viruses reproduce inside cells)Antibiotics generally work by destroying the cell walls of bacteria. The flu is caused by a virus, which is not a cell and does not have a cell wall. Antibiotics cannot be used against viral diseases.
Which Gran Positive or negative which is more serious?
Gram positive bacteria responds to the Gram stain; gram negative bacteria does not. The two bacteria do not respond to the same antibiotics. Right now the most dangerous bacteria is a gram negative bacteria. That could change.
Why does an antibiotic not work the same for all bacteria?
Bacteria also do evolve. If one bacteria is mutated, and survives an attack by antibiotic, he multiplies and forms more bacteria which are more resistant against antibiotic. As days of surviving antibiotics and multiplying eventually creates a bacteria which is resistant against it.
Do hormones in meat affect us physically?
I'm not sure if you could specify? I just learned about antibiotics in biology this year (I'm a sophomore) and I can tell you something though: do not give antibiotics to your animals to promote growth. It is sorta like taking antibiotics when you're sick. They help you, but can be deadly. It goes the same for animals too. Antibiotics can be deadly because there are such things that may exist in our bodies called MUTANT BACTERIA STRAINS. These strains will not respond to antibiotics when the other bacteria die off. MUTANT BACTERIA STRAINS will stay alive. and worse, multiply. And then you have a whole swarm of mutant bacteria strains in your body that can't be taken away with antibiotics. So when you give certain livestock antibiotics to promote growth, you're risking possession of mutant bacteria in your body when you eat their meat. The animal may have mutant bacteria strains already and you don't know it. So when you eat the animal, you're risking getting these bacteria strains. Sorry if that didn't help, but you may have learned something vital instead.
How do microogarnisms avoid being attacked by antibiotics?
They don't. They develop a resistance to it. Just like people, each bacteria is slightly different even from bacteria of the same type. Some are slightly more resistant to a given drug than others. What happens is that when someone is given antibiotics and the drugs are not enough to kill all the bacteria only those that are most resistant to that drug remain. Even worse is when someone decides they feel better and stop taking their antibiotics. Then the bacteria split and/or share their genes with other bacteria and as a result that resistance is passed on to future generations.
