IVDR Class A Certified Leprosy Bacillus Stain 4x100ml For Healthcare Facility
Leprosy Bacillus Stain 4x100ml Baso Clear Colourful Stains for Healthcare Facility
Testing Princinple
Mycobacterium such as Mycobacterium tuberculosis and Mycobacterium leprae are difficult to stain because of their lipoid capsule in the cell wall. However, once the lipoid capsule is stained with an enhanced dye such as carbolfuchsin, the newly formed compound will resist decolorization from acid-alcohol and retain the original color stained (red), which can be easily differentiated from other microorganisms that still adsorb the counter blue stain. Because the acid resistance of leprosy bacilli is relatively weak, it cannot decolorization with traditional 3% hydrochloric alcohol solution. It can only decolorization with low concentration of hydrochloric acid or dilute sulfuric acid, otherwise the red will easily be removed. This product uses low concentration of hydrochloric acid as a decolorization solution.
Stain Results
In light blue background, acid-fast bacteria such as leprosy are red, and other bacteria and cells are blue.
The length of the Leprosy bacilli was 1~8 um, and the wide between 0.2~0.5 um, slightly curved elongated bacilli, morphologically like tuberculous bacilli, but relatively thick and short; No flagellum and no spores. Arranged in parallel or bundled or stacked into a cluster. Sometimes it is called "leprosy cells" in the foamy cells of the lesion.
