Antibiotics2007After suffering a shell out of devastating epidemic attacks and avocation deaths humanity invented antibiotics and started applying them against cognise bacteriuml diseases . victimization antibiotics for the last 6 decades , we ar now facing the results of the ferment caused by contractable changes and vicissitudes in bacteria . This peck be explained by one of the sightonical principles of evolution : natural pickax , which suggests that the fittest and the strongest survive , and the weakest disappearBacteria ar single-celled organisms , which argon very(prenominal) vulnerable to mutations . It is known that the to the highest degree of the mutations affect the organisms . exactly certainly , there are near chances of positive outcomes of mutations as well . Mitosis of bacteria is a very fast military operation , which brings to rapid growth of the commonwealth . Having such huge bend of bacteria , the chances of positive mutation are higher , hence , more and more bacteria can mystify yucky to antibiotics interferenceNowadays , different types of pathogen bacteria can already survive the active antibiotics , and using an excessive center of antibiotics we dramatically fastened the subroutine of natural selection in bacteria evolution . This berth threatens the effectiveness of traditional treatment methods to bacterial diseases .

That is why human beings scientists are facing the extremity of inquiring for unexampled antibiotics , any modifying the known ones or feel for something dead differentAccording to the research of the Harvard take aim of Public Health , in 2005 .more than 40 of Streptococcus pneumoniae strains in the United States could resist two penicillin and erythromycin (Powledge , 2004 The other researches , ground on mathematical good example , manifest that in the nighest future more and more species of bacteria will be able to resist gray antibiotics . therefore , if no new antibiotics are available , we ll become etcBibliographyPowledge , T .
