<s>[INST] My friend 45, male, had a knew replacement three years ago and now he has developed staph infection and he is in bad shape. I heard about staphage lysate that a dr. Used to save his heart patient that developed staph and was three months in the hospital some years back and when nothing worked he used this staphage lysate and saved his life. Any ideas. [/INST] thanks for posting your query to hcm . staph infection can be treated using antibiotics . I suggest you to investigate for culture and sensitivity of your infected material and then start antibiotics according to its sensitivity . Staphage lysate is in treatment of animal for recurrent staph infection , its routien clinical use in human beings is not practiced . </s>
