In this paper a novel computer example-based learning system (Inductive learning by logic minimization) was used to determine the sufficient set of biochemical reactions and necessary conditions that have to be fulfilled for the correct identification of enterococci isolated from human specimens. Several combinations for accurate identification of Enterococcus faecalis and Enterococcus feacium from other enterococci were found. The simplest combination set for E. faecalis identification consists of 3 reactions: growth in 0.04% K-tellurite, mannitol acidification, failure to acidify raffinose. The simplest set for E. faecium differentiation from other enterococcal species is performed by the following 3 reactions: failure to acidify D-xylose and Na-pyruvate, and acidification of L-arabinose. Only 4 tests are sufficient (acid from D-xylose, mannitol, L-arabinose and Na-pyruvate) for the correct identification of these two, the most frequently isolated species. If it is necessary to analyze all enterococcal species, then even three combinations of 9 tests for the correct differentiation of any of them, are available.
在本文中，一种新型的基于计算机示例的学习系统（通过逻辑最小化进行归纳学习）被用于确定从人类标本中分离出的肠球菌正确鉴定所需的生化反应充分集和必要条件。发现了几种从其他肠球菌中准确鉴定粪肠球菌和屎肠球菌的组合。用于鉴定粪肠球菌的最简单组合集由3个反应组成：在0.04%亚碲酸钾中生长、甘露醇酸化、棉子糖不酸化。从其他肠球菌物种中区分屎肠球菌的最简单组合由以下3个反应进行：D-木糖和丙酮酸钠不酸化，以及L-阿拉伯糖酸化。仅4项测试（来自D-木糖、甘露醇、L-阿拉伯糖和丙酮酸钠的酸）就足以正确鉴定这两种最常分离出的物种。如果有必要分析所有肠球菌物种，那么甚至有9项测试的三种组合可用于它们中任何一种的正确区分。
