Bacterial resistance to antibiotics has increased since their introduction almost 50 years ago. Some strains of bacteria, sych as golden staph , are now completely antibiotic resistant. Superbugs are becoming increasingly prevalent, a natural reaction by bacteria, to antibiotics.

In Australia , The CSIRO has come up with a new way to fict bacteria, introducing the newest generation of antibiotics.

The Antibiotics for the Future project aims to develop compounds that will jam up the DNA making machinery of bacteria.


Will this have the effect of curing the diseases antibiotics seek to treat? Or will we see a new, even stronger generation of superbugs rise as a result of this project?

its hard for a bacteria to change its DNA polymerase III molecule wich in this article they see as a target. It could happen offcourse :], but the changes are not as big as with 'old' antibiotics. The sites in Pol III are probably highly conserved and very important for its replication..
There are also other strategys being develloped like the use of RAMPS, ribosomaly synthesized antimicrobial peptides, the natural defence for living organism against infections

Yes i heard this that antibiotics will be useless in 12 years or so.
Is this because the viruses are mutating to beat the anti bodies then???????
Ive personally never used anti biotics to my knowledge would that makew me more immune to certain diseases.

I have had antibiotics in the past, but the only drugs I take now are asprin, tylonol (dont want to spell it), ibuprofin (sp?), speed (pseudoephedrine), and alcohol.

I disagree with 'the flu shot'. I think it just makes things worse for those that get the shot. I take my 3-4 days of being sick and then move on with my life.

And just in case you are wondering, the pseudoephedrine is in my allergy medicine.

i doesnt make u more immune nor does it help u in another way, its the bacteria that get resistent to the antibiotics so if u get infected there as useless as with somebody that used AB before..Antibiotics dont have any use in antiviral treatment, they dont work on virusses. I think the flu immunisation can be usefull although there will always be different flu-virusses emerging at the sametime who are not in the cocktaill but its good to protect 'weaker' people against the common ones for that year..
