Abstract
Abstract A procedure for detection of Neisseria gonorrhoeae in a microbial growth culture. Lysates of the suspect organism are tested by reverse passive hemagglutination with particles sensitized with antibodies to eleven N. gonorrhoeae strains, ATCC 31397, 31398, 31399, 31400, 31401, 31402, 31403, 31404, 31405, 31406, and 31407.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
79 words
A procedure for identification of a microorganism as N. gonorrhoeae, said procedure comprising: preparing a lysate of the microorganism; contacting a sample of said lysate with a suspension of discrete particles sensitized with antibodies to N. gonorrhoeae strains ATCC 31397, 31398, 31399, 31400, 31401, 31402, 31403, 31404, 31405, 31406, and 31407; incubating said mixture of lysate and particles; and determining the presence of agglutination of said incubated mixture indicative of the positive identification of the microorganism as N. gonorrhoeae.
Claim 2
Dependent Claim
79 words
A procedure for identification of a microorganism as N. gonorrhoeae, said procedure comprising: preparing a lysate of the microorganism; contacting a sample of said lysate with a suspension of discrete particles sensitized with antibodies to N. gonorrhoeae strains ATCC 31397, 31398, 31399, 31400, 31401, 31402, 31403, 31404, 31405, 31406, and 31407; incubating said mixture of lysate and particles; and determining the presence of agglutination of said incubated mixture indicative of the positive identification of the microorganism as N. gonorrhoeae.
Claim 3
Dependent Claim
51 words
A reagent for use in a reverse passive hemagglutination assay for identification of a microorganism as N. gonorrhoeae, said reagent comprising: a suspension of discrete particles, surface portions of which are sensitized with antibodies to N. gonorrhoeae strains ATCC 31397, 31398, 31399, 31400, 31401, 31402, 31403, 31404, 31405, 31406, and 31407.
Claim 4
