Antibiotics2007After suffering a make do of devastating epidemic attacks and mess deaths humanity invented antibiotics and started applying them against cognise bacteriuml diseases . Using antibiotics for the last 6 decades , we be now face up the results of the process caused by transmitted changes and mutations in bacterium . This prat be explained by i of the basic principles of evolution : ind puff uping selection , which suggests that the fittest and the strongest survive , and the weakest disappearBacteria atomic number 18 one-celled organisms , which ar authentically vulner equal to mutations . It is known that the some of the mutations affect the organisms . But for certain , there are some chances of positive outcomes of mutations as well . Mitosis of bacteria is a really fast process , which brings to fast growth of the population . Having such huge number of bacteria , the chances of positive mutation are higher , therefore , to a greater extent and more bacteria give notice become resistant to antibiotics treatmentNowadays , unlike types of pathogen bacteria can already survive the existing antibiotics , and exploitation an excessive amount of antibiotics we dramatically fastened the process of intrinsic selection in bacteria evolution . This situation threatens the metier of traditional treatment methods to bacterial diseases .

That is why world scientists are facing the necessity of interfering for new antibiotics , either modifying the known ones or looking for something unawares differentAccording to the research of the Harvard School of national Health , in 2005 .more than 40 of Streptococcus pneumoniae strains in the linked States could resist both penicillin and erythromycin (Powledge , 2004 The other researches , based on mathematical modeling , precede that in the nearest upcoming more and more species of bacteria will be able to resist old antibiotics . and then , if no new antibiotics are available , we ll become etcBibliographyPowledge , T .
