Alternative to antibiotics - preparation for post antibiotic era

Emergence of resistance against antibiotics is perhaps leading towards a stage of total ineffectiveness of these medicines as some tools to protect lives from infection of pathogenic micro organisms. The research communities are trying in various ways to find out means and tools to overcome such possible situation. The leading contemporary researches going on globally are categorized under some headings. These are - alteration and/or addition of some new chemicals with the presently available anti microbial substances to bring back their potency, searching of some new means of attack on harmful micro organisms by use of other microorganisms or their products, acceleration of immunity power of human or animals by using the tools present in the microorganisms, use of some new types of substances and procedures against microorganisms which were not previously used and use of antimicrobial, immune-stimulant and other related substances developed in higher species through evolution. Present stages of research of the included parameters are analyzed in the article.
