Exercise 6-C STAINING OF MICROORGANISMS ACID-FAST STAIN Introduction The acid-fast stain is a differential stain that separates bacteria on the basis of the lipid content of their cell walls. Because they have thinner layer of peptidoglycan in their cell wall. Because degree of acid fastness is different for different organisms. Proteus organisms are implicated as serious causes of infections in humans, along with Escherichia, Klebsiella, Enterobacter, and Serratia species.

Thanks. Fix the smear onto the slide by passing over the flame of Spirit lamp or Bunsen burner. However, Proteus species are not the most common cause of nosocomial infections. P. vulgaris is tolerant of high concentrations of heavy metals or toxic substances, and can even manipulate these as a source of energy or nutrition (1). Lastly, to determine which is a gram negative and gram positive, a gram stain test was used. For the gram-negative bacteria, I had trouble with this from the beginning. The swarming of Proteus can be inhibited by, Culture characteristics of Proteuson XLD Agar medium Dalynn The colonies are small, glistening and usually, the growth is irregular due to swarming.
