1. Meanwhile, biochemical reaction, coagglutination test, metabolism-inhibition test, polymerase chain reaction (PCR), and DNA sequence assay were employed to identify those positive cultures.

2. Ten coagglutination of the reagent with various strains of gonococcus and other bacteria showed specificity and sensitivity.

3. Biochemical reaction, coagglutination test, metabolism inhibition test, polymerase chain reaction (PCR) assay, and DNA sequencing were employed to identify the isolated microorganisms.

4. What is SPA coagglutination test? What is the usage of it?

5. A kit for detecting 16 strains of pathogenic bacteria that cause fish diseases mainly by SPA coagglutination assay(SPA-COA)were clinically applied within 7 provinces in china from 1995 to 1997.
