Evaluation of the rapid NFT system for identification of gram-negative, nonfermenting rods.
This study evaluated the ability of the Rapid NFT system (API System SA, Montalieu-Vercieu, France) to accurately identify 262 clinically isolated, gram-negative, nonfermentative rods without additional tests. Identifications were classified as correct; low discrimination, with a spectrum of two or more possibilities (additional tests necessary for accurate identification); and incorrect. Corre...
متن کاملCritical evaluation of the AutoMicrobic system gram-negative identification card for identification of glucose-nonfermenting gram-negative rods.
During a 6-month study we critically evaluated the accuracy of the AutoMicrobic system Gram-Negative Identification Card (Vitek Systems, Inc., Hazelwood, Mo.) in identifying glucose-nonfermenting gram-negative bacilli by testing 419 selected isolates in parallel with a conventional reference method. Of 356 isolates included in the AutoMicrobic system profile, a total of 307 (86.2%) were correct...
متن کاملEvaluation of two rapid methods for identification of commonly encountered nonfermenting or oxidase-positive, Gram-negative rods.
The ability of the expanded API-20E and the Oxi-Ferm System to identify 176 isolates of nonfermenting or oxidase-positive, gram-negative rods from 17 species or groups was studied. The expanded API-20E, without referral to a computer reference center, was able to identify 61.4% of the isolates to the species level. If reference to the computer center was utilized, an additional 25% could be ide...
متن کاملEvaluation of the VITEK 2 system for rapid identification of medically relevant gram-negative rods.
The new VITEK 2 system (bioMérieux) was evaluated at two independent sites with the identification card for gram-negative bacilli (ID-GNB card). Of the 845 strains tested, which represented 70 different taxa belonging to either the family Enterobacteriaceae or the nonenteric bacilli, 716 (84.7%) were correctly identified at the species level. Thirty-two (3.8%) additional strains were identified...
متن کاملBiochemical and susceptibility tests useful for identification of nonfermenting gram-negative rods.
Six hundred nineteen strains of nonfermenting gram-negative rods were tested for alkaline phosphatase, benzyl-arginine arylamidase, pyrrolidonyl arylamidase, ethylene glycol acidification, and susceptibility to desferrioxamine and colistin. The results were highly discriminant. Therefore, the proposed tests may be helpful for the identification of this group of organisms.
