Antibiotics2007After suffering a band of devastating epidemic attacks and heap deaths humanity invented antibiotics and started applying them against cognize bacteriuml diseases . utilise antibiotics for the last 6 decades , we ar now facing the results of the mould caused by contractable changes and variants in bacteria . This peck be explained by one of the rudimentary principles of evolution : natural selection , which suggests that the fittest and the strongest survive , and the weakest disappearBacteria ar one-celled organisms , which argon very(prenominal) vulnerable to mutations . It is known that the to the highest degree of the mutations affect the organisms . only if certainly , there are near chances of positive outcomes of mutations as well . Mitosis of bacteria is a very fast transition , which brings to rapid growth of the macrocosm . Having such huge be of bacteria , the chances of positive mutation are higher , because , much and more bacteria can buoy bring forth revolting to antibiotics treatmentNowadays , different types of pathogen bacteria can already survive the alert antibiotics , and using an excessive meter of antibiotics we dramatically fastened the exhibit of natural selection in bacteria evolution . This locating threatens the effectiveness of traditional treatment methods to bacterial diseases .

That is why creation scientists are facing the prerequisite of inquiring for current antibiotics , any modifying the known ones or face for something dead differentAccording to the research of the Harvard instill of Public Health , in 2005 .more than 40 of Streptococcus pneumoniae strains in the United States could resist twain penicillin and erythromycin (Powledge , 2004 The other researches , found on mathematical framework , manifest that in the closest future more and more species of bacteria will be able to resist aged antibiotics . therefore , if no new antibiotics are available , we ll become etcBibliographyPowledge , T .
