Abstract

Duplicate cultures of 53 strains representing 9 species of Neisseria were analyzed by gas-liquid chromatography for cellular fatty acids. N. sicca, N. mucosa, N. flava, N. flavescens, N. perflava, N. subflava, and the several serotypes of N. meningitidis examined were found to comprise a fairly homogeneous group on the basis of the percentages of individual fatty acids present. Lactose-fermenting Neisseria also were in this group. N. catarrhalis, however, contained decanoic acid in addition to the acids occurring in the other species. Moreover, the 18 C-saturated and monoenoic acids together constituted 36% of the total fatty acid composition for N. catarrhalis, while the comparable mean value for the other species was less than 13%.

摘要

对代表9种奈瑟菌属的53株菌株进行重复培养,采用气液色谱法分析其细胞脂肪酸。根据所存在的各脂肪酸百分比,发现微黄奈瑟菌、粘膜炎奈瑟菌、浅黄奈瑟菌、淡黄奈瑟菌、全黄奈瑟菌、亚黄奈瑟菌以及所检测的几种脑膜炎奈瑟菌血清型构成了一个相当同质的群体。乳糖发酵奈瑟菌也在该群体中。然而,卡他莫拉菌除了含有其他菌种中存在的酸外,还含有癸酸。此外,18碳饱和脂肪酸和单烯酸占卡他莫拉菌总脂肪酸组成的36%,而其他菌种的可比平均值小于13%。
