Is there are different type of antibiotics for different problem or condition and If yes what kind. Is this antibiotics even treat both bacterial as well as viral infection. Reply with information, please.
Antibiotics are effective against certain bacteria not conditions. They are usually prescribed using empiric therapy, which means the doctor is aware of the most common organisms that may cause a certain infection and hand out an agent that the bacteria is susceptible to. Of course this doesn't always work and testing must be done to nail down the exact bacteria and what it is/isn't resistant to.
Like has been posted antibiotics kill or slow down bacteria. Yes different antibiotics are more successful at treating different conditions and specific bacteria. Also bacteria is becoming resistant to different antibiotics. This is especially worrisome as no new ones have been successfully developed in a few years and we use these amazing medicines for the craziest widespread uses.. effectively providing astounding conditions for resistance to happen in a very large scale and very quickly. A great example is the use of antibiotics to increase production in agriculture.. its not used to protect the animals.. its used to produce more. scary and real stuff.
Antivirals are used to treat viruses and viral flare ups. Once some one has a virus they likely will have it for life.. Viruses particles are very small and can not reproduce themselves, they rely on a host to reproduce them. But they also are so similar and hide in such inaccessible places that its very hard to get rid of them.
Americans use to many antibiotics as it is. We have been programmed to think that every cough and sniffle requires an antibiotic and many hound the doctor until they get it. Add in all the antibiotics that are in our food and you have a group of people who are helping bacteria to become immune to the antibiotics that a few years earlier would have easily killed them.
Killer Bacteria and Zombie Viruses may not be to far behind.......
The resistance in healthcare is astounding. I don't think the poster's question is specific enough though for me to go much into it. I don't understand what exactly the poster wants to know. Yes, specific antibiotics treat specific conditions. The best, and only way, imo to determine this is to culture what you are treating. No, you cannot use antibiotics for viral infections.
If you're asking because you have some antibiotics around and don't want to go to the doctor, it's best just to go. What appears to be a simple infection can be something else. Medications also tend to loose their potency over time, in the lab we keep most antibiotics in the fridge/freezer to keep their potency for a longer period of time.
If that's not why you're asking, then I'll go with what everyone else said
Sometimes antibiotics are prescribed when someone has a virus prophylacticly. I've had doctors do this for me, sometimes to take immediately, sometimes only if things get worse, as I'm prone to certain types of infections.
Resistant strains of bacteria are a main problem of people not finishing their scripts of antibiotics. When they don't they only kill part of the bacterial infection causing the rest to either be hopefully killed of by the body but in rare cases now more prevalent the bacteria just evolve inside the body and pass on to the next host. Staph is becoming so prevalent. I work in an er and the majority of staph infections I see are shared through or brought by iv drug use.
Yes though different antibiotics are prescribed for different infections. One of the most powerful against all of them though are doxycycline pills. While in the navy they would prescribe them for antimalaria treatments but it also covers a wide variety of treatment for other things. Down side is the shit makes you sick as fuck to the stomach and causes severe headaches even with food.
