Almost immediately the majority of infectious diseases caused by bacteria could be cured and it is estimated that this has increased global life expectancy by 10 years. The fear of these infec- tions was instantly removed. Soon after the introduction of antibiot- ics, resistant bacteria began to emerge. These resistant bacteria were largely checked by the discovery of new antibiotics and infections caused by them continued to be controlled; however, the era of new drugs is now long past and the proportion of bacteria resistant to the current antibiotics continues to increase. This is most keenly felt in hospitals where there are now incidences of bacteria causing severe infections that are resistant to virtually every antibiotic avail- able to treat them. The judicious use of antibiotics and the control of the spread of resistance are now the responsibility of all health- ix care workers who deal with infectious diseases and no longer the duty of just the microbiologist. Failure by all stakeholders in healthcare to recognise the problems of antibiotic resistance is likely to lead to a bleak outlook for future treatment of bacterial infections. This book not only describes the antibiotics themselves but also draws attention to the problems of resistance and how it needs to be considered when prescribing these drugs.

Description:
Although antibiotics are among the most widely used pharmaceuticals, they are also often inappropriately and over-prescribed. Indeed there are increasing predictions that unless we moderate our use of these drugs, bacterial resistance will eventually render them useless. As there are no serious cont
