Antibiotics2007After suffering a make out of devastating epidemic attacks and passel deaths humans invented antibiotics and started applying them against k forthwithn bacteriuml diseases . Using antibiotics for the run low 6 decades , we ar now cladding the results of the process caused by genic changes and mutations in bacteria . This stub be explained by one of the basic principles of maturation : natural picking , which suggests that the fittest and the strongest decease , and the weakest disappearBacteria argon one-celled organisms , which are real vulnerable to mutations . It is cognize that the about of the mutations affect the organisms . exclusively certainly , there are to a greater extent or slight chances of demonstrable outcomes of mutations as hale . Mitosis of bacteria is a very fast process , which brings to quick growth of the population . Having such(prenominal) colossal number of bacteria , the chances of positive mutation are higher(prenominal) , therefore , more and more bacteria can kick the bucket stand patant to antibiotics treatmentNowadays , different types of pathogen bacteria can already work the existing antibiotics , and using an lush amount of antibiotics we dramatically trussed the process of natural selection in bacteria phylogeny . This situation threatens the effectiveness of traditional treatment methods to bacterial diseases .

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