Eye: Neisseria meningitidis – Shipped August 2012
The challenge was sent to category A and B laboratories. The sample was a simulated eye swab obtained from a 3 year old patient with conjunctivitis.
Participants were expected to isolate and identify Neisseria meningitidis. Correlation with results obtained for the companion Gram challenge (G122) was also expected.
MAIN EDUCATIONAL POINTS from M122-3
- Correctly identifying N. meningitidis from conjunctival samples is important because the treatment is different than that of most other bacterial entities.
- Neisseria species, including N. meningitidis, can cause a hyperacute bacterial conjunctivitis that is severe and sight threatening.
