Bacteriophage: laboratorial diagnosis and phage therapy Braz

Bacteriophages have been researched as a new alternative to antibiotics. These viruses inject their genetic material into bacteria and use their host machinery to multiply themselves. The research of bacteriophages in Brazil will certainly provide low-cost treatment of multidrug resistant bacteria, new microbiological diagnosis and advantages for the Brazilian food industry. Key words: Phage-based therapy, bacterial diseases, antibiotic resistant bacteria Phage therapy is the use of lytic phages to treat or to prevent bacterial infections. The knowledge about phage therapy obtained so far permit us to consider these viruses as a powerful weapon against bacteria (6). During billions of years the Nature has shaped these natural killers leaving for us the responsibility of making use of them for our own cure. The discovery of antibiotics shrunk phage therapy research in the west countries in that phage biology was not satisfactory understood and antibiotic-based treatment provided mor
