1972年肠杆菌科仅有11个属26个种,而今已有22个属69个种和29个生物群或肠道菌群。本文讨论了所有这些新种和群,它有一系列有助于鉴定的图表和一个列有98种细菌常用的鉴定47种试验的表。详表的简化表列出了最常见种和最常用的鉴定试验,列出了新种和生物群的来源,并讨论了它们在人类疾病中所起的作用。本文首次描述了肠杆菌科的14个新群。它们的生化特征不同于已描述过的肠杆菌科的种、生物群和肠道菌群。这些新群是枸椽酸菌属 amalonatjcus 生物群Ⅰ、克雷伯氏菌群47、(吲哚阳性、鸟氨酸阳性)、沙雷氏菌 marcescens 生物群Ⅰ、和不能分类的肠道菌群17、45、57、58、59、60、63、64、68、69。
In 1972, only 11 genera and 26 species were found in Enterobacteriaceae, and now there are 22 genera and 69 species and 29 biota or intestinal flora. This article discusses all of these new species and subgroups, with a series of charts that help identify and a list of 47 tests commonly used to identify 98 species of bacteria. The detailed tables provide a list of the most common and commonly used identification tests, listing the sources of new species and biota, and discussing their role in human disease. This article first describes 14 new groups of Enterobacteriaceae. Their biochemical characteristics are different from the species, biota and intestinal flora of the Enterobacteriaceae that have been described. These new groups are Citrobacter amalonatjcus biotype I, Klebsiella pneumoniae 47, (indole-positive, ornithine-positive), Serratia marcescens biome I, and non-classifiable gut flora 57, 58, 59, 60, 63, 64, 68, 69.
