用自配的改良ＧＣＹＳＢ－Ｖ选择培养基从２２５份临床标本（痰和咽拭子）中分离到嗜血杆菌属细菌９７株（流感嗜血杆菌６８株），而用加万古霉素的普通巧克力选择培养基（Ｃｈｏｃ－Ｖ）从相同标本中只分离到嗜血杆菌属细菌２９株（流感嗜血杆菌１９株），分离率相差显著（Ｐ＜０．０１）。流感嗜血杆菌在两种培养基上的平均生长指数（ＧＩ）分别为７．７２和５．９４（Ｐ＜０．００１）。结果表明，ＧＣＹＳＢ培养基比Ｃｈｏｃ培养基更适合流感嗜血杆菌生长。
97 strains of Haemophilus bacteria (Haemophilus influenzae 68 strains) were isolated from 225 clinical specimens (sputum and throat swabs) using a self-formulated modified GCYSB-V selection medium, while the common There were only 29 strains of Haemophilus bacteria (19 strains of Haemophilus influenzae) isolated from the same samples in Choc-V medium, the separation rates were significantly different (P <0.01). The average growth index (GI) of Haemophilus influenzae on both media was 7.72 and 5.94, respectively (P <0.001). The results showed that GCYSB medium was more suitable for Haemophilus influenzae growth than Choc medium.
