Product Introduction:

Spirochaeta is a kind of slender, spiral and moving prokaryotic microorganisms. It has the basic structure of bacteria, and the cell wall has lipopolysaccharide and wall acid. Spirochetes are divided into dense spirochetes (such as Treponema pallidum), Borrelia (such as regressive heat spirochete), Leptospira, etc. Treponema pallidum has 8 ~ 12 uniform spirals with straight ends; Leptospira are slender, numerous and dense. One or both ends are bent in hook shape, and the bacteria often bend in C-shape or S-shape. Treponema pallidum and Leptospira can be colored by silver plating, such as Levaditi method and Warthin starry method.

Spirochete Staining Kit (Levaditi Method) uses Leptospira to adsorb silver ions from silver solution under specific conditions. After treatment with reduction solution, the adsorbed silver ions are reduced to black metal silver for color development. The staining solution is mainly used to display Treponema pallidum and Leptospira, but less heat regression spirochete. It can distinguish between hepatic syphilis gumma and hepatic Leptospira.
