The same, unknown bacteria is isolated from 20 sick individuals. their samples were grown in culture and then placed in 10 healthy mice. those mice started to show signs of a heightened immune response. to determine if the bacteria is pathogenic, what is the next step by using koch’s postulates?
a. classify the bacteria as a noncommunicable disease.
b. classify the bacteria as a communicable disease.
c. reisolate it, and determine if it is the original unknown bacteria.
d. treat the original 20 individuals with antibiotics.

C.Reisolate it, and determine if it is the original unknown bacteria.

Explanation:

Koch's postulates correspond to a protocol that cites necessary steps for a researcher to establish a relationship between a microorganism and a disease, being able to affirm whether the microorganism is pathogenic or not.

In relation to the question above, we can see that the battery was inoculated in the mice, so that the symptoms it causes could be observed. In this case, according to Koch's postulates, the missing step in this experiment is the re-isolation of the bacteria, so that it is possible to determine whether it is an original unknown.

option a and d is the correct answer

i hope this u
