Question

what do you conclude from Karl Landsteiner experiment​

Answer 1

Landsteiner performed autopsies on the rhesus monkeys that revealed spinal cord lesions like those observed in human polio victims. Because Landsteiner and Popper had eliminated bacteria as a potential cause of the infection earlier in the experiment, they concluded that a virus must have caused the infection.

Answer 2

Karl Landsteiner, ForMemRS, was an Austrian biologist, physician, and immunologist. He distinguished the main blood groups in 1900, having developed the modern system of classification of blood groups.
