The micro-organism shown in the photomicrograph above represents Neisseria gonorrhoeae.The female patient is suffering from Gonorrhea.
- Morphology of Neisseria gonorrhoeae: Gram-negative cocci that typically appear in pairs with the opposing sides flattened (a “kidney bean” appearance).
- The complement system is an essential component of the innate immune defence against infection by Neisseria (N. Meningitidis and N. gonorrhoeae).
- People who lack or have a deficiency in complement mediated bactericidal activity are most susceptible to neisserial diseases.
- Vaccinations for encapsulated organisms is crucial for preventing infections in complement deficiencies
