title: [Evaluation of the GonoGen II kit for rapid identification of Neisseria gonorrhoeae using monoclonal antibody directed at gonococcal outer membrane protein 1].
abstract: The Gonogen II test for rapid identification of Neisseria gonorrhoeae (Gonococcus, GC) was evaluated. The test is based on a colorimetric reaction with monoclonal antibody to GC outer membrane protein 1. Of the 50 clinical isolates of GC, 49 isolates tested positive and only one strain tested negative. Other Neisseria. spp, H. influenzae, H. parainfluenzae, E. corrodens, M. catarrhalis, and A. baumannii showed negative test results. Non-Neisseriae. spp, such as S. aureus. P. aeruginosa, E. faecalis, and E. coli also showed negative test results. No cross-reactivity was found between GC and other Neisseriae. spp or non-Neisseriae. spp. In a mixed suspension of GC and all of non-Neisseriae. spp as mentioned above, the GonoGen II test was positive. The specificity and sensitivity of the test for the identification of GC were 98% and 100%. The minimum limit of detection of GC was > or = 1 x 10(5) cfu/mL. Decision making based on the test result is possible within 10 minutes. These findings also suggest that the test does not require pure GC. The GonoGen II test appears to be a reliable, quick and easy-to-use assay, and also to not require viable GC. Thus GonoGen II is shown to be a very useful test for the identification of GC.
