can somebody pls help me with my coursework. I ve 0nly got 2 days to do it. my teacher is very rigorous and i need to obtain a grade A to pass. the subject title is the effects of antibiotics on gram positive and gram negative bacteria. any sugestions???????? pleeeeez help ti gon.
All i know about this subject is that antibiotics stops the bacteria from dividing... Maybe Patrick knows some usefull sites for you...
I'd like to help but the question is a bit to vast to be answered here. There are books of more than 1000 of pages specifically treating the subject of which antibiotic is efficient against which kind of bacteria.
I found an interesting review on the subject here http://www.merck.com/mmhe/sec17/ch192/ch192a.html
It may help you start, but if you were more precise about what you need, or the limit of your subject I could give a more complete answer.
hiya yea sorry about the indistiction of my question. the bacterias i am using are ecoli and S.epidermis and the the antibiotics are ampicillin and Kanamycin. can you believe i have got to do a 100 pages on the subject??? its just absurd!! i practically begged for an extension and i got a 2 day extension. i really need to get this completed and i think with the help of my new friends patrick and Mr Mistry i hope i will have it done thanks alot pal XXXXXXXxxxx
Patrick is the one you should thank. I am just in the dark on this subject as you are.
Sorry but I come back from a long week-end. I do really not see how you could do 100 pages on the subject with only 2 genus of bacteria and 2 antibiotics! Sure it is not 10 pages?
But what you could do:
- Determination of the minimal inhibitory concentration (MIC) of both antibiotics on both bacteria: Find a medium that is suitable for both (Mueller-Hinton is usually the one recommended, but I'm sure wether S. epidermis would grow on it) either agar plates or broth. Prepare different concentration of antibiotic and inoculate with approximately 10^6 bacteria per ml. Grow @37C for 16 to 20h and note which concentration inhibits growth. (in case of broth make triplicate experiment). Compare MIC for both species and discuss.
-Use Medline and the links I gave you and try to identify the targets of your antibiotics to compare the composition of the targets for both species.
- Have a lot of illustrations
Back in the lab for further questions. Good Luck
