The bacteria lactobacillus acidophilus is used as a probiotic therapy for gastro intestinal upset. why would a doctor deliberately infect a patient with a bacteria culture?

He would intentionally infect a patient with the bacteria in the culture because Lactobaccilus acidophilus is not a harmful bacteria and doe not cause any illness. Instead, it is a probiotic and fights with those harmful bacteria inside the patient's body.

The answer is atmosphere. there are four spheres of the earth: 1. geosphere (from greek word 'geo' = ground), 2. hydrosphere (from greek word 'hydro' = water), 3. biosphere (from greek word 'bio' = life), and 4. atmosphere (from greek word 'atmo' = air). a magnetosphere is a region of space around astronomical objects controlled by the magnetic field of that object. through the process of elimination, since lightning is present in the air, it can be found in the atmosphere.
