Q: You guys know any drugs used for bacterial pneumonia?
I need some drugs/medicines that are used for bacterial pneumonia..please give me the drug and for what bacteria it is used for
ex. erythromycin - staphylococcus pneumoniae
give as much as u can and i'll be giving out 10's
A: Good Grief !!!!! I hope you don't need to go to the doctor--
If you are the doctor please tell me where NOT to go !
Q: Any drugs that can cure Bacterial Vaginosis without medical prescription?
It seems like all the medicine that used to cure BV need doctor's prescription.
A: It's better to use a perscription, I know there are over-the-counter medicines for yeast infections, but I'm not sure about bacterial vaginosis.
Q: Why do drugs that act on bacterial and fungal membranes generally have high tocxicity?
NEED HELP
A: Bacterial and Fungal cell membranes are made up of phospholipids just like the human cell membranes. And this is why antibiotics that act on cell membranes are not that specific in their toxicity.
Q: two questions about bacterial drug resistance?
1) what are some factors that lead to bacteria being resistant to drugs?
2) what can be done to stop this?
A: Most antibiotics boast that they kill 99% of bacteria. Well, why doesn't this 1% die? Because they are stronger than the rest of the bacteria. These strong bacteria then reproduce and now our antibiotic is less effective because now (after a while) we've created superbacteria
We need to stop using antibiotics for things that aren't bacterial infections. Like the cold for instance
Q: Why is it easier to use drugs to cure bacterial diseases than those caused by fungi/protists/animal parasites?
A: Bacteria are prokaryotes, while fungi/protists/animal parasites are eukaryotes.
Humans are also eukaryotes.
Thus, bacteria are different from all of the rest. It is easier to make drugs to target this difference and in a way not affect the stuff that eukaryotes have.
When you make drugs against fungi/protists/animal parasites, you target stuff that all eukaryotes, including humans, have in common. Therefore, humans can get more side effects from these medications since they are also eukaryotes.
Q: how do Beta lactum drugs affect bacterial strucrure?
A: Beta lactams interfere with a particular protein that is required for cell wall synthesis. without the cell wall, bacteria are very susceptible to destruction by immune systems, and by osmosis. The protein is called PBP - penicillin binding protein. Most of the early beta lactams are far more effective against gram positive organisms because they have more of a cell wall.
Bacteria can alter the PBP so that it is resistant to the beta lactam. they can also make an enzyme that breaks down the beta lactam, making it ineffective.
Q: Can Viral and Bacterial infections work as a sort of team in the body?
If someone has a bacterial and viral infection at the same time and recieves drugs for the bacterial infection only.As the bacterial symptoms disappear so too can the viral symptoms . Can one be somehow linked to the other?
A: Viruses and bacteria are different life form, its like comparing a monkey and a goat. They have similarities but are different species.
It is possible to have both a virus and a bacterial infection at the same time but antibiotics will only work on the bacteria. they would have no effect on the viral infection. With the bacterial infectured treated the patient woiuld still show symptoms of the viral infection. Viral infections are usually less severe and self limiting;

Q: What if I have a nasal bacterial infection and don't treat it with antibiotics?
I know it is bad to use antibiotics for a viral infection, but what if I choose not to take drugs for a bacterial infection? If I have a good immune system and don't feel very sick, won't I just get better naturally?
A: You certainly can fight a bacterial infection without the benefit of antibiotics. After all antibiotics simply assist our own defense system in fighting an infection. If you are free of fever or serious symptoms from an infection that should have symptoms, then I see no good reason to take the medication. There are infections that are known to be symptoms free, though (example: Chlamydia). Sinusitis can have mild symptoms, so be sure you understand the whole story before you elect to skip your medication. When in question, discuss the matter with your doctor or someone on his staff.
Good luck.
Q: How would I go about obtaining a bacterial strain?
I'm a junior in high school but taking a college Biology course and as my year-long project I want to research the effects of different drugs on a type of bacterial strain. Or how different bacterial strains are affected by a specific drug.
(By drug, I mean Tylenol or Benedryl for example)
How would obtain a bacterial strain? I'm not sure what kind of strain I would use as of now but I'm trying assess whether this idea is even do-able with my resources and capabilities.
Please help!
A: I would recommend that you pick another project. Microbiology is very fascinating, but if you're not trained in the field, stuff can go wrong. For instance, by swabbing a site on your body and then culturing it, you would likely grow some interesting (and safe) bacteria....or you might cultivate a pathogen. Two pathogens that immediately come to mind (that you can find on your body) are Staphylococcus aureus (causes food poisoning, toxic shock, etc) and Streptococcus pyogenes (causes strep throat). If you are untrained in this field, these are not organisms you want growing in a petri dish.
Q: Ethan is studying viral and bacterial diseases. Which of the following is NOT an accurate comparison of bacter?
Ethan is studying viral and bacterial diseases. Which of the following is NOT an accurate comparison of bacteria and viruses?
a) Most viruses enter cells whereas most bacteria do not.
b) Bacterial genes are made of DNA whereas viral genes may be made of DNA or RNA.
c) Bacterial infections are more susceptible to drugs.
d) Bacteria may secrete toxins whereas viruses do not.
e) Bacterial genes are made of DNA whereas viruses lack genes and use host cell genes.
A: E
A is correct. B is quite correct; there are many RNA viruses including HIV. C and D are correct.
E is incorrect because viruses all have genes. At the minimum, they have the genes to encode viral structural proteins.
Q: I want to perform a demo in a presentation about drug resistant bacterial and viral infections?
What should I do?
A: Are you in college? If you are, or have access to someone that is. You could use visual aids such as petri dishes. When I took microbiology in college we grew bacteria in petri dishes full of nutrient agar and placed impregnated discs of antibiotics to show growth restriction around the discs. You could use a placebo disc to show growth on and around the discs as if the bacteria were immune to the antibiotics. If you don't have access, make visual aides to simulate this. If you need help, I have some old pics from my classes to help you out. Just shoot me a message.
Q: a chemo drug kills bacterial cells, but not human cells. Why does the drug act selectively on bacteria?
What is the difference that would make a chemotheraputic drug act differently on the two cells?
A: bacteria contain peptidoglycan in their cell walls this is a substance not found in humans at all so we develope drugs which target this specifically.
our problem is with viruses. they use our own cells and cell processes to reproduce so to kill virus we must kill our own cells
Q: Why do some of the most successful antibiotics target bacterial RNA polymerase?
Antibiotics are drugs that selectively kill bacteria without harming animals. Many antibiotics act by selectively binding to certain proteins that are critical for bacterial function.
A: RNA polymerase in bacteria is the source of replication. If the RNA polymerase is damaged and cannot operate then the transcription of the RNA is not possible. This means that cell division is not possible to continue because there is not a copy of the bacterial RNA present for the new cell. This would allow your white blood cells to isolate the remaining bacteria and dispose of them. Antibiotics that bind to certain protein sequences are helpful but your body also contain these sequences in some of their enzymes.
Q: What medical drugs were used during WWI?
I'm comparing medical advancements between the civil war and WWI but I can't find much about which particular drugs were used to treat patients. Like, what sorts of anasthesia or painkillers were used. Anything about surgery or bacterial knowledge around this time would help me out as well.
A: Anesthesia would have been ether I believe. There weren't a lot of drugs available. Penicillin was not yet around. People died from infections. I think these links will help you.
