Answer 1

The purpose of inoculating blood into blood culture bottles using a butterfly apparatus is to test for the presence of bacteria in the blood.

Step-by-step explanation:

When blood is inoculated into blood culture bottles using a butterfly apparatus, the purpose of this procedure is 1) To test for the presence of bacteria in the blood.

Blood culture bottles contain a growth medium that promotes bacterial growth, allowing any bacteria present in the blood to multiply. The butterfly apparatus is used to draw a sample of blood into the culture bottle, providing a suitable environment for bacterial growth.

If bacteria are present in the blood, they will multiply and can be detected through visual examination or additional laboratory tests.
