Critical 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 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 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.
متن کاملFour methods for identification of gram-negative nonfermenting rods: organisms more commonly encountered in clinical specimens.
Four commercial kits, Oxi/Ferm (OF), API 20E (AP), Minitek (MT; BBL Microbiology Systems), and Flow N/F (NF), were evaluated, without additional tests, for identification of 258 gram-negative nonfermentative rods. OF and MT were read after 48 h of incubation, and AP and NF were read after both 24 and 48 h of incubation, respectively. Overall, OF correctly identified 51% of strains, with 46% as ...
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...
