The invention discloses a
capsule staining method for
streptococcus pneumonia, and relates to the field of microbiological detection. The
capsule staining method comprises the following steps: (1) preparing a bacterium specimen; (2) performing smearing, namely uniformly smearing a clean slide with a small amount of bacterium specimen, scraping the bacterium specimen into a
thin layer, and naturally air-
drying the slide; (3) performing
staining: namely adding dropwise 100 to 150 microliters of carbolic
acid fuchsin staining liquor onto the slide to uniformly cover the slide, and naturally air-
drying the slide; (4) performing mordanting, namely washing the slide, naturally air-
drying the slide, adding dropwise a
mordant to uniformly cover the slide for 3 to 5min, rinsing the slide with water, and naturally air-drying the slide; (5) performing microscopic examination. The
capsule staining method for
streptococcus pneumonia is simple, easy, low in time consumption and high in success rate and
repeatability, and has excellent application prospect in the
clinical diagnosis of pneumonia, and strains of
streptococcus pneumonia can be rapidly and efficiently identified.
