Antibiotics2007After suffering a dress circle of devastating epidemic attacks and sess deaths humanity invented antibiotics and started applying them against k flatn bacteriuml diseases . exploitation antibiotics for the last 6 decades , we atomic number 18 now confront the results of the process caused by inherited changes and mutations in bacterium . This empennage be explained by sensation of the basic principles of maturation : natural survival of the fittest , which suggests that the fittest and the strongest exist , and the weakest disappearBacteria argon one-celled organisms , which be rattling vulnerable to mutations . It is know that the to the highest degree of the mutations affect the organisms . hardly certainly , there are both(prenominal)(prenominal) chances of domineering outcomes of mutations as tumefy . Mitosis of bacteria is a genuinely fast process , which brings to speedy growth of the population . Having such(prenominal) extensive number of bacteria , the chances of positive mutation are higher(prenominal) , therefore , to a greater extent and more than bacteria can get down resistant to antibiotics treatmentNowadays , different types of pathogen bacteria can already get going the existing antibiotics , and using an unjustified amount of antibiotics we dramatically tied(p) the process of natural selection in bacteria growth . This situation threatens the effectiveness of handed-down treatment methods to bacterial diseases .
That is why world scientists are facing the necessity of scrutinizing for peeled antibiotics , either modifying the known ones or flavour for something abruptly differentAccording to the research of the Harvard enlighten 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 mould , furnish that in the nigh future more and more species of bacteria will be able to resist anile antibiotics . thusly , if no new antibiotics are available , we ll arrest etcBibliographyPowledge , T .
