A child presents with meningitis symptoms, is unvaccinated, and has Gram-negative pleomorphic coccobacilli in their CSF culture. Which bacteria matches the description: A. E.coli B. Haemophilus influenzae C. Neisseria meningitidis D. Listeria monocytogenes
Understand the Problem
The question describes a clinical scenario of a child presenting with meningitis-like symptoms, with a Gram-negative pleomorphic coccobacillus identified in their cerebrospinal fluid (CSF) culture and no prior vaccination. The question asks to determine which bacterium best fits this description from the given options. We need to choose the organism that is Gram-negative, pleomorphic (meaning it can exist in various shapes), and commonly manifests as coccobacilli (short, oval, bacillus-like shape) in CSF cultures causing meningitis, especially in unvaccinated children.
Answer
B. Haemophilus influenzae
The bacteria that matches the description is Haemophilus influenzae. Therefore, the answer is B.
Answer for screen readers
The bacteria that matches the description is Haemophilus influenzae. Therefore, the answer is B.
More Information
Haemophilus influenzae is a Gram-negative pleomorphic coccobacillus that can cause meningitis, especially in unvaccinated children.
Tips
It's important to consider the Gram stain and morphology (shape) of the bacteria, as well as the patient's vaccination status, to narrow down the possible causes of meningitis.
