BACKGROUND Commercial diagnostics are commonly used to identify gram-positive bacteria. Errors have been reported mostly at the species level. We have found certain phenotypic criteria used in API systems which significantly misidentify Leuconostoc, an emerging human pathogen, at the genus level. We also attempt to find practical, conventional phenotypic assays for accurate identification of th...

The API ZYM system was compared with four anaerobe identification systems for the definitive identification of Clostridium difficile by using 88 cultures of C. difficile grown on Mueller-Hinton blood agar medium. The API ZYM system yielded a distinct and consistent enzyme profile for all test strains, whereas the sensitivities of the other systems in identifying C. difficile ranged from 78 to 9...

The API Staph Strip system (API System S.A., Montalïeu-Vercieu, France) was compared with conventional methods for identification of Staphylococcus hyicus isolated from cases of exudative epidermitis in swine. The API Staph Strip was found to provide unique profile numbers, namely, 6-514-151, 6-514-153, and 6-516-153. These profile numbers are not listed in the API Staph Strip data base. It was...

The API 20E system for Enterobacteriaceae, recently broadened to include identification of nonfermentative gram-negative bacteria, was evaluated and compared with the conventional method for complete identification of 221 nonfermenters, which were well distributed into 48 species or biotypes and included organisms not listed in the API 20E data base. The results of 16 tests common to both syste...

The API 20E and Oxi/Ferm systems were tested in parallel to identify nonfermentative bacteria and oxidase-positive fermentative bacteria. Test strains consisted of consecutive clinical isolates, with stock cultures used to supplement those species infrequently recovered. The two microsystems, as well as tubes of triple sugar iron, motility, cetrimide, and oxidative glucose media, were inoculate...

The API 20E, the Enterotube, and routine methods of Cowan and Steel were used in parallel to identify 245 members of the Enterobacteriaceae. The API 20E and conventional methods gave the same identification in all but 2 (0-8%) of the 245 organisms tested. The Enterotube correctly identified 85% of these organisms on the first testing. On re-testing those organisms incorrectly identified the Ent...

Fifty-five isolates of coagulase-negative staphylococci from blood were identified four times each by using the API Staph-Ident (API-SI) system to determine the identification reproducibility of the system. Identifications were determined by using both Version 1 and Version 2 of the API-SI Profile Index. The 75 to 100% reproducibility levels, including reproducible nonidentifications, were 98.2...

One hundred strains were referred to us for identification because they apparently could not be identified satisfactorily with the API 20E system (appareils et procédés d'identification). The inability to identify 31 strains was due primarily to failure to follow the manufacturer's instructions. Twenty six further strains were found to have been correctly identified by the sender's own API 20E ...

The API STAPH-IDENT system was compared with conventional methods for the identification of 14 Staphylococcus species. Conventional methods included the Kloos and Schleifer simplified scheme and DNA-DNA hybridization. The API STAPH-IDENT strip utilizes a battery of 10 miniaturized biochemical tests, including alkaline phosphatase, urease, beta-glucosidase, beta-glucuronidase, and beta-galactosi...
