Test reproducibility of the API (20E), Enterotube, and Pathotec systems.
Thirty-three strains of bacteria (30 Enterobacteriaceae and one strain each of Aeromonas formicans, A. hydrophila, and Plesiomonas shigelloides) were tested three times in each of 27 conventional tests and in the API, Enterotube, and Pathotec systems. The results obtained were analysed for test reproducibility within each kit, correlation of the kit tests with the equivalent conventional media,...
متن کاملMisuse and interlaboratory test reproducibility of API 20E system.
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 ...
متن کاملReproducibility of the analytab (API 20E) system.
The reproducibility of the Analytab (API 20E) system for identification of Enterobacteriaceae was evaluated with 110 clinical isolates. Each isolate was identified by two technologists at different times. Genus-species identification was 97.3% reproducible; however, only 55.5% of the strains gave identical reactions in all 20 of the API 20E biochemical tests on repeat testing. Of those strains ...
متن کاملIdentification of the Enterobacteriaceae: a comparison of the Enterotube II with the API 20E.
Two commercial methods for the identification of the Enterobacteriaceae, API 20E and Enterotube II, were compared using the results obtained with 235 cultures of fresh clinical isolates. Enterotube II was an improvement on the original Enterotube, but the availability of two differing indices, one using the Voges-Proskauer (VP) test result and one without, is criticised.
متن کاملA comparison of two commerical methods for the identification of the Enterobacteriaceae--API 20E and the Enterotube--with conventional methods.
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...
