Description

We studied the basic performance of eight rapid diagnostic kits for the detection of Group A streptococcus by immunochromatography under the same conditions. Kits were the QuickVue Dipstick Strep A (Sumitomo Seiyaku Biomedical Co., Ltd.), TESTPACK Plus STREP A (ABBOTT JAPAN Co., Ltd), CLEAVIEW STREP A (Nihon Schering K. K.), QuickVue STREP A (Wako Pure Chemical Industries, Ltd), ImmunoCard STAT! STREP A (TFB, INC.), DIPSTICK ‘Eiken’STREP A (Eiken Chemical Co., Ltd.), Rapid Testa Strep A (Daiichi Pure Chemical Co., Ltd.), and StatCheck Strep A (KAINOS Laboratories, Inc.).<BR>Four of these kits, i.e. QuickVue Dipstick Strep A, TESTPACK Plus STREP A, Rapid Testa Strep A, and StatCheck Strep A showed sensitivity at 1.0×105CFU/mL (1.0×104CFU/test) with all ofS.pyogenestested, while the Anginosus group andS. dysgalactiaesubsp.equisimiliswith Lancefield' s group A antigen showed sensitivity very similar toS. pyogenes.<BR>Of these strains, S. dysgalactiaesubsp.equisimilisformed a β-hemolytic colony resembling that ofS. pyogeneson sheep blood agar, and was sensitive to bacitracin. It is thus indispensable to identify the colony using biochemical tests such as the PYR (pyrrolidonylarylamidase production) test.<BR>In using rapid diagnostic kits for the detection of Group A streptococcus, it is important to rule out the possibility of Group A streptococcus other thanS. pyogenesin throats.<BR>Severe invasive group-G streptococcal infections are increasing recently. ConcerningS. dysgalactiaesubsp.equisimilis, it is especially important to conduct these identification tests.
