Herein we present a short historical review of the evolution of AF staining methods and discuss Koch's paradox, in wh … Of these, 53 animals had one or more positive faecal cultures or had post-mortem histopathological evidence of infection. Some cultures have additional special release conditions Acid-fast (AF) staining, also known as Ziehl-Neelsen stain microscopic detection, developed over a century ago, is even today the most widely used diagnostic method for tuberculosis. In conclusion, the results of this study indicate that M. phlei MbP18 has benefi cial eff ects on plant growth under saline conditions through its ability to produce diff erent biologically active compounds such as cell wall-degrading enzymes and the phytohormone auxin.
