Disease-causing bacteria more resistant to antibiotics. Development of medications should be re-turned to nature. The findings of the antibiotic penicillin by Alexander Fleming in 1928 became a potent antidote to the infection that attacks the human race. Until 1970, biologists assumed that disease caused by infection can already stripped of human history.
The fact that ensued showed a lot of emerging infectious diseases, such as pneumonia, AIDS, and SARS. Meanwhile, old infectious diseases are also re-emerged in the community.
"Antibiotics were found previously not been able to cope with infectious diseases," said Jan Verhoef, micro-biology researchers from Utrecht University, during a speech at the Conference Internasionai Eijkman, Tuesday, November 8, 2011.
For decades, the bacteria modify themselves to be more resistant to antibiotics. One of the enzymes that play a role in this immune enhancement is a beta-lactamase, which can be easily transferred from bacterium to another.
On the other hand, the spread of antibiotic resistant enzyme is made easier along with the expansion of farming activities around the world. Livestock production also spread more rapidly into the population so that the beta-lactamase move rapidly to the bacteria that cause infections in humans.
In recent decades, experts mikrobioiogi attempt to discover new antibiotics to fight infection. The development of antibiotics is done by engineering chemical extracts. Unfortunately, a serious effort is lead to failure.
The development of antibiotics are now resorting to ingredients that are found naturally in nature. But this search was not easy, many potent natural antibiotics to fend off infection, but are toxic to humans. As a result, these new antibiotics can not be found.
According to Jan, the discovery of natural antibiotics is still very open. Currently new scientists could find 1 percent of the biodiversity that exists in nature. If the listing is expanded, the closer to natural antibiotics found. *** [ANTON WILLIAM | KORAN TEMPO 3702]
