Abstract

The glucose nonfermenting gram-negative bacilli encountered about 10% of all gram-negative bacilli isolated from clinical material. Therefore, a rapid and correct identification of glucose nonfermenting gram-negative bacilli is impotent for a better management of infectious disease. There are many conventional systems for the identification of glucose nonfermenting gram-negative bacilli but most of them have problems and difficulties. Commercial Kit Systems exist and they are too expensive for daily use in Korea because of high cost. Based on 12 selected tests we propose a new code system, MCRCODE-N for rapid and inexpensive identification of glucose nonfermenting gram-negative bacilli. The selective 12 tests are oxidase, glucose oxidation motihty, urease, DNase arginine dehydrolase, nitrate reduction, gelatin Liquefaction, esculin hydrolysis, mannitol oxidation, maltose oxidation, Lactose oxidation. The 12 tests are divided 4 group and then each group has 3 tests. The result of each group is expressed by the number as below. The positive test is given by specific number (1st test=1, 2nd test=2, 3rd test=4), while any negative result is 0. Each 3 numbers of one group are added and make number of 1 digit. Four digit number is referred to the code book of MCRCODE-N system or MCRCODE system using computer (Apple-II model) created by authors. This MCRCODE-N system is suitable ones for out use in Korea. We propose the MCRCODE-N system for clinical use.
