Antibiotics2007After suffering a lot of devastating epidemic attacks and inner circle deaths humanity invented antibiotics and started applying them against know bacteriuml diseases . Using antibiotics for the last 6 decades , we argon now facing the results of the process caused by genetical changes and mutations in bacteria . This fag be explained by oneness of the introductory principles of development : natural selection , which suggests that the fittest and the strongest suffer , and the weakest disappearBacteria atomic turn 18 one-celled organisms , which argon rattling vulnerable to mutations . It is known that the approximately of the mutations affect the organisms . But certainly , there are some(a) chances of positive outcomes of mutations as well . Mitosis of bacteria is a in truth fast process , which brings to rapid growth of the population . Having such(prenominal) commodious number of bacteria , the chances of positive mutation are higher(prenominal) , therefore , more and more bacteria can fetch resistant to antibiotics treatmentNowadays , different types of pathogen bacteria can already survive the existing antibiotics , and using an excessive amount of antibiotics we dramatically attach the process of natural selection in bacteria evolution . This situation threatens the effectiveness of traditional treatment methods to bacterial diseases .

That is why world scientists are facing the necessity of seek for stark n aked antibiotics , either modifying the know! n ones or looking for something abruptly differentAccording to the look for of the Harvard School of Public Health , in 2005 .more than 40 of streptococcus pneumoniae strains in the United States could resist both penicillin and erythromycin (Powledge , 2004 The other(a) researches , based on mathematical modeling , acquaint that in the nearest future more and more species of bacteria go away be able to resist old antibiotics . whence , if no new antibiotics are available , we ll become etcBibliographyPowledge , T .
