The rise in antibiotic resistance is reaching worrying levels, experts say.The rise in antibiotic resistance is reaching worrying levels, experts say.

For instance, 12% of bloodstream infections by E. coli in England, Wales and Northern Ireland now show some signs of not responding to drugs.For instance, 12% of bloodstream infections by E. coli in England, Wales and Northern Ireland now show some signs of not responding to drugs.

There are two main families of bacteria known as gram-positive, such as MRSA, and gram-negative, which includes E. coli and other less common bugs Acinetobacter and Pseudomonas.

The HPA said there had been a drive to tackle MRSA in recent years which had helped reduce infection rates and led to a host of new antibiotics to be developed.The HPA said there had been a drive to tackle MRSA in recent years which had helped reduce infection rates and led to a host of new antibiotics to be developed.
By comparison, the development of antibiotics targeting gram-negative bacteria such as E coli, which can cause a range of symptoms from mild diarrohea to abdominal cramps and kidney damage, was much less common.

The fight against drug resistance is an on-going battle because many bacteria constantly mutate, gaining resistance to current antibiotics in the process.The fight against drug resistance is an on-going battle because many bacteria constantly mutate, gaining resistance to current antibiotics in the process.

HPA data shows that there are about 20,000 bloodstream infections of E. coli each year - although the true level of infections would be much higher if urinary tract infections were taken into account.

The infections are mostly not yet resistant to all forms of antibiotics, just what doctors call the first-line.The infections are mostly not yet resistant to all forms of antibiotics, just what doctors call the first-line.
This means they are having to use back up drugs, which tend to have more side effects and raises the prospect of the widespread emergence of a new strain which is totally antibiotic resistant.This means they are having to use back up drugs, which tend to have more side effects and raises the prospect of the widespread emergence of a new strain which is totally antibiotic resistant.
