Antibiotics2007After suffering a lot of devastating epidemic attacks and grass deaths humanity invented antibiotics and started applying them against cognise bacteriuml diseases . Using antibiotics for the last 6 decades , we atomic number 18 now facing the results of the process caused by inherited changes and mutations in bacteria . This empennage be explained by sensation of the basic principles of exploitation : natural selection , which suggests that the fittest and the strongest detain , and the weakest disappearBacteria argon one-celled organisms , which argon rattling vulnerable to mutations . It is known that the to the highest degree of the mutations affect the organisms . But certainly , there are both(prenominal) chances of positive outcomes of mutations as well . Mitosis of bacteria is a real fast process , which brings to rapid growth of the population . Having such(prenominal) gigantic number of bacteria , the chances of positive mutation are higher(prenominal) , therefore , more and more bacteria can engender resistant to antibiotics treatmentNowadays , different types of pathogen bacteria can already hold up the existing antibiotics , and using an excessive amount of antibiotics we dramatically fix the process of natural selection in bacteria evolution . This situation threatens the effectiveness of traditional treatment methods to bacterial diseases .

That is wherefore world scientists are facing the necessit y of scrutinizing for youthful antibiotics! , every modifying the known ones or looking for something abruptly differentAccording to the research of the Harvard naturalize 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 researches , establish on mathematical modeling , furnish that in the nearest future more and more species of bacteria will be able to resist old antibiotics . thusly , if no new antibiotics are available , we ll become etcBibliographyPowledge , T .
