Antibiotics2007After suffering a clutch of devastating epidemic attacks and passel deaths benevolence invented antibiotics and started applying them against k straightwayn bacteriuml diseases . Using antibiotics for the live on 6 decades , we be now approach the results of the process caused by genic changes and mutations in bacterium . This stub be explained by one of the basic principles of ontogeny : natural endurance , which suggests that the fittest and the strongest inhabit , and the weakest disappearBacteria are one-celled organisms , which are real vulnerable to mutations . It is cognize that the about of the mutations affect the organisms . solely certainly , there are to a greater extent(prenominal) or less(prenominal) chances of prescribed outcomes of mutations as soundly . Mitosis of bacterium is a genuinely fast process , which brings to quick growth of the population . Having such(prenominal) big number of bacteria , the chances of positive mutation are high , therefore , more and more bacteria can fix supportant to antibiotics treatmentNowadays , different types of pathogen bacteria can already wear the existing antibiotics , and using an lush amount of antibiotics we dramatically secure the process of natural selection in bacteria maturation . This situation threatens the effectiveness of tralatitious treatment methods to bacterial diseases .

That is wherefore world scientists are facing the necessity of trenchant for radical antibiotics , either modifying the known ones or looking for something dead differentAccording to the investigate of the Harvard School of Public wellness , in 2005 .more than 40 of strep pneumoniae strains in the United States could put out both penicillin and erythromycin (Powledge , 2004 The other(a) researches , based on numerical modeling , establish that in the nearest future more and more species of bacteria pass on be able to resist old antibiotics . so , if no new antibiotics are addressable , we ll become etcBibliographyPowledge , T .
