Antibiotics2007After suffering a lot of devastating epidemic attacks and tummy deaths humanity invented antibiotics and started applying them against know 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 resist , 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 genuinely fast process , w hich brings to rapid growth of the population . Having such(prenominal) commodious number of bacteria , the chances of positive mutation are high , therefore , more and more bacteria can go resistant to antibiotics treatmentNowadays , different types of pathogen bacteria can already pull round the existing antibiotics , and using an excessive amount of antibiotics we dramatically laced 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 scrutinizing for new-spr ung(prenominal) antibiotics , each modifyin! g the known ones or looking for something abruptly differentAccording to the research of the Harvard schooling 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 close 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 .
