There will be no differentiate bw afb and non-afb, bz, there is no enough penetration of carbol fuschin to the cytoplasm thats why decolorizer flushes off the fuschin, and there will be counterstaining of methylene blue to both type of bacteria if that is AFB or non-AFB. In this test, the result showed a clearing around the streak of bacteria indicating that it was a positive result. Positive (+ve) This complex is a larger molecule than the original crystal violet stain and iodine and is insoluble in water.

Alternate decolorizing reagent (without alcohol): Slowly add 250 mL sulfuric acid (at least 95%) to 750 mL distilled water. Due to a special wax in their cell membrane, these organisms do not readily take up dye from a typical gram stain. Am pascal studying medical lab in technical university Kumasi Ghana.my question is both carbol fuchsin and methylene blue are basic dyes, so what will happen if we use methylene blue as our primary stain? Recent research has shown that P. vulgaris can be used in industrial settings, for example, to create biodiesel using an engineered lipase from the bacteria and a transesterification reaction triggered by sonication (12) The P. vulgaris lipase was made more thermostable through the introduction of a disulfide bond in the enzyme. %%EOF Arrangement Of Cells Pr. what is media choice of growing Proteus mirabilis.
