INCREASING BACTERIOAL RESISTANCE AT THE COST OF HUMAN ( HOST ) RESISTANCE

INCREASING BACTERIOAL RESISTANCE AT THE COST OF HUMAN ( HOST ) RESISTANCE

Antibiotics are invaluable to treat infections and save lives.

Since the invention of Penicilin, dozens of antibiotics have been discovered and developed, natural and synthetic / semisynthetic.

An antibiotic is an biochemical product of some organisms devised to keep them safe from other invading / offending organisms, i.e. their enemies.

As we all know, the aim of antibiotic therapy is to arrest the growth of offending bacteria or to kill them. Primarily a group of disease producing organisns may be sensitive to a particular antibiotic, so that they are killed by that. But with time they tend to design device to inactivate the antibiotic or render themselves unaffected by the same by way of mutation. So newer antibiotics are needed to fight them.

Drug resistance is an obvious challenge to the medical science. The researchers are always busy developing newer weapons for pathogens ( disease producing microbes ).

Microbial resistance to drugs is increasingly evolving ..............

while human resistance to disease is constantly decreasing.

How ?
