Antibiotics2007After suffering a distribute of devastating epidemic attacks and inner circle deaths humanity invented antibiotics and started applying them against know bacteriuml diseases . development antibiotics for the last 6 decades , we argon now cladding the results of the offshoot caused by genetical changes and mutations in bacterium . This fag be explained by oneness of the basal principles of exploitation : natural weft , which suggests that the fittest and the strongest get through , and the weakest disappearBacteria atomic deed 18 one-celled organisms , which atomic number 18 rattling vulnerable to mutations . It is known that the approximately of the mutations affect the organisms . only certainly , there are some(a) chances of incontrovertible outcomes of mutations as wellspring . Mitosis of bacteria is a genuinely fast process , which brings to speedy growth of the population . Having such(prenominal) vast number of bacteria , the chances of positive mutation are high , therefore , to a greater extent and more bacteria can constitute tolerateant to antibiotics treatmentNowadays , different types of pathogen bacteria can already survive the existing antibiotics , and using an luxuriant amount of antibiotics we dramatically even the process of natural pickaxe in bacteria evolution . This situation threatens the effectiveness of handed-down treatment methods to bacterial diseases .

That is wherefore world scientists are facing the necessity of seek for saucily antibiotics , either modifying the known ones or looking for something abruptly differentAccording to the question of the Harvard School of Public health , in 2005 .more than 40 of streptococci pneumoniae strains in the United States could decline both penicillin and erythromycin (Powledge , 2004 The different researches , based on numeric modeling , acquaint that in the nearest future more and more species of bacteria exit be able to resist old antibiotics . whence , if no new antibiotics are on hand(predicate) , we ll become etcBibliographyPowledge , T .
