The result, showed a clearing or halo ring around the streak of bacterium. Then the smear is decolorized with decolorizing agent (3% HCL in 95% alcohol) but the acid fast cells are resistant due to the presence of large amount of lipoidal material in their cell wall which prevents the penetration of decolorizing solution. Albert stain for confirmation to show green tail and reddish metachromatic granules.

Acid-fastness is an uncommon characteristic shared by the genera Mycobacterium and Nocardia (weakly acid-fast). One study researching alternative methods for urinalysis found that urea levels could be detected using electrochemical signaling from redox reactions that take place on the surface membrane, specifically the conversion of urea to ammonia (8). Ziehl-Neelsen Stain name is from the surnames of German doctors, bacteriologist Franz Ziehl(1859-1926), and pathologist Friedrich Neelsen (1854-1898).

Volatile indole produced by rhizobacterium Proteus vulgaris JBLS202 stimulates growth of Arabidopsis thaliana through auxin, cytokinin, and brassinosteroid pathways. Finally, blood agar is always really cool for p. mirabilis, because the organism has a tendency to swarm across the agar (because of its high motility), so thats cool to see. Omitting the step could lead to false results since the cabolfuchsin might be de-colorized leading to false negative results. Over the past two decades, the genus Proteus, and in particular P. vulgaris, has undergone a number of major taxonomic revisions.
