Using the scientific method, what is the problem we are trying to solve here?

What is the hypothesis for the solution to the problem? (What organism do you think caused the problem)

What are the experiments that are required to answer your hypothesis?
(The stains, biochemical, and media for each organism and the expected results)

What is the conclusion to the problem? (Based on the expected results, what organism caused the problem?)

Problem: Which bacteria is causing the meningitis in the patient - Neisseria meningitidis or Haemophilus influenzae?

Hypothesis is defined as theoretical or hypothetical explanation of observations and measurements. The working hypothesis in this case is: Most likely, Neisseria meningitidis is the bacteria that is causing meningitis because it is more common. H. influenzae is usually associated with meningitis in infants and young children, but since 1990, HIB conjugate vaccine against H. influenzae has reduced the incidents of H. influenzae-related meningitis to very low levels. On the other hand, Neisseria meningitidis is very contagious and is easily spread when the bacteria from an upper respiratory infection enter the bloodstream. ...
