Antibiotics2007After suffering a lot of devastating epidemic attacks and passenger vehicle 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 maturation : natural selection , which suggests that the fittest and the strongest dwell , and the weakest disappearBacteria argon one-celled organisms , which are 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 very(prenom inal) fast process , which brings to rapid growth of the population . Having such(prenominal) Brobdingnagian number of bacteria , the chances of positive mutation are higher(prenominal) , therefore , more and more bacteria can flex resistant to antibiotics treatmentNowadays , different types of pathogen bacteria can already support the existing antibiotics , and using an excessive amount of antibiotics we dramatically fastened the process of natural selection in bacteria evolution . This situation threatens the effectiveness of traditional treatment methods to bacterial diseases .

That is wherefore world scienti sts are facing the necessity of scrutinizin! g for spick-and-span antibiotics , either modifying the known ones or looking for something abruptly differentAccording to the research of the Harvard shallow 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 , ground on mathematical modeling , furnish that in the closest 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 .
