New Year Greetings - 2014!
Antibiotics, also known as antibacterials, are types of medications that destroy or slow down the growth of bacteria. Antibiotics are used to treat infections/illness caused by bacteria. The first antibiotic, penicillin, was discovered in 1929 by Sir Alexander Fleming. There exists several penicillin-related antibiotics as ampicillin, amoxicillin and benzylpenicilllin and are widely used to treat a variety of infections.
In the past 6 decades or so, they have played a crucial role in fighting against infectious diseases caused by bacteria and other microbes. Antimicrobial chemotherapy has been a leading cause for the increase of average human life span in the 20th Century. However, certain pathogenic microbes (that cause wound infections, gonorrhea, tuberculosis, pneumonia, etc.) have developed resistant, at genetic level, against antibiotic drug therapy. Several reasons could be attributed for such resistance, that they are remarkably resilient and development of resist antibiotics and other antimicrobial drugs. The increased use and misuse of existing antibiotics in human and veterinary medicine and in agriculture are the prime factor for their resistance. Microbial development of resistance, as well as economic incentives, have resulted in research and development in search for new antibiotics in order to maintain a pool of effective drugs at all times.
In this context, this issue highlights evolution of environmental microbial population on antibiotic resistance, its secretary system and drug resistance mechanisms. Other interesting reports on antibiotic resistance are also included.
