The meningococcal meningitis epidemic has been observed in Ankara in the last 3 years. Cases were from all parts of the country. Most of the strains isolated were from group B, while many could not be classified, and some of them were from group C, A and D. Because of fewer cases from group A and more from group B and C, the epidemic was not the classical meningococcal meningitis, but an intermediate one. Many cases could not be classified with the classical A, B, C, and D antisera. This showed that different serological groups existed in the country and should be taken into consideration in laboratory work.
过去3年里，安卡拉出现了脑膜炎球菌性脑膜炎疫情。病例来自该国各地。分离出的菌株大多属于B群，有许多无法分类，还有一些属于C群、A群和D群。由于A群病例较少，B群和C群病例较多，此次疫情并非典型的脑膜炎球菌性脑膜炎，而是一种中间类型。许多病例无法用经典的A、B、C和D抗血清进行分类。这表明该国存在不同的血清学群，在实验室工作中应予以考虑。
