Phage therapy is the use of bacteria-specific viruses (phages) to control and kills the diseases causing bacteria. 

Step-by-step explanation

In phage therapy, we use bacterial viruses to control the infectious or disease-causing bacteria. These viruses kill those pathogenic bacteria The phage therapy is very effective against antibiotic-sensitive and antibiotic-resistant bacteria and is very safe. 

Benefits of Phage Therapy:

1. Safe, convenient, and economic 
2. minimally disrupt normal flora as compared to the antibiotic
3. Phage is the best bacteriocidal agents as compared to the antibiotic which only stops the growth of the bacteria and there are chances of bacterial resistance 
4. The phage therapy is auto dosing and phage number increase automatically where the bacterial density is higher in the host
5. Phages are non-toxic as compared to the antibiotic which can cause toxicity in the body of the host
6. Phages have narrow host ranges so there is very less chances of getting resistance against phages
