pleaseeeeee help me answer this:

in terms of biology what are the comsequences of over using antibiotics

[k02033]

Bacteria have a very high mutation rate, due to their rapid reproduction. These mutations allows some bacteria to have natural resistance to antibiotics. Hence when antibiotics are used, these resistant bacterias survive to reproduce and pass on its genetic resistance. without competition from non resistant bacteria, these surviving bacteria dominant the population over time thus reducing effectiveness of antibiotics.

antibiotic resistance causes problems as it renders present, low Cost antibiotic to be virtually useless for treatment for frequently seen infections. this leads to the invention and use of new, costly antibiotics.

this again quickly leads to resistance. this could mean that easily treatable infections today may be untreatable in the future.

u know thanx alot, ma answer it found afterwoods is very similr but thanx (in a goooooood way)

is there by any chance that anyone knows how vaccines prevent infection, it doesn't seem to make sense

[_blank]

Yeah it's confusing because they don't really "prevent" infections, so much as allowing for a much more rapid response the next time you encounter the infection.

But I think what it means is that it "prevents" infections by stopping the pathogen in its tracks, before it can attack the body and develop into a full infection.

This may also clarify: HSC Online

HOW does the vaccines evelauate the effectiveness of vaccine programs

[possessionless]

vaccines definatly do not prevent infections.
ive had whooping cough vaccination twice & ive still got it now!

maybe coz the virus has adapted to ur immnue system and that u need a another type of vaccine or medication or somefin to strengthen ur immne system more

its not a virus its bacteria.
arent those memory B & T cells meant to do something? lol

okey sori i meant bacteria, it may seem that u may have a weak immune system towards such bacteria or even the bacteria has become adapted to ur immunisation. The more u use the same vaccine the less effective it is.

it's like cocraches spray the more u use the same spray the less effective it is that's why every 6 months they need to change it.

all 4 of your T cells r broken =) jokes lol

Nah. Not quite.

Vaccines stimulate the body's immune response, causing stimulation of the production of antibodies needed to fight off a particular pathogen (or antigen). This usually occurs because vaccines contain either a dead or inactive form of the pathogen, so the recepient does not develop symptoms of the disease (generally). The antibodies respond to the antigen in the vaccine, and memory cells remain in the body so that a later infection will be recognised, and can be fought off much faster and easier.
