| Outline of Final Research Achievements |
In order to investigate whether superantigens (SAgs) are involved in the development of Kawasaki Disease (KD) by examining SAg genes in patients with KD, throat specimens were obtained from a total of 34 KD patients who fulfilled diagnostic criteria on admission. These samples were cultured with liquid culture solution of Brain-Heart Infusion Broth under 37℃ during overnight. Total DNA was extracted from these cultured bacterial solution. Using polymerase chain reaction, we examined the genes of five SAgs: streptococcal pyrogenic exotoxin-A (SPE-A), SPE-C, SPE-G, SPE-J, and Toxic Shock Syndrome Toxin-1. SPE-G, SPE-A, and SPE-J genes were detected in 3, 4, 8 specimens from KD patients. Two SAg genes of SPE-G and SPE-J were detected in one patients of KD. Now, we continue the examines for the identification of bacterial species of bacteria keeping SAg genes.
