In Liquid culture media like Trypticase soy broth or Nutrient broth & Peptone Water, the growth of the bacterium occurs as a uniform turbidity in the broth medium with a powdery deposit and Ammoniacal smell which is further analyzed for the morphology (under the microscope), gram reaction, biochemical tests, and Proteus Vulgaris specific tests. Well nicely quoted P. vulgaris has also been identified as the main microbial pollutant in drinking water of Rajasthan, India (23). Acid-fast mycobacteria contain mycolic acid in their outer membrane, making the cells waxy and resistant to staining with aqueous based stains such as the Gram stain.

Nitrate test was performed, test showed to be positive after the reagents were added. 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. Thus confiming the unknown specimen to be Bacillius cereus. Help. Treponema pallidum is the causative agent of syphilis. For example, several antibiotic-resistant strains of P. vulgaris were identified in the intestines of shrimp in Turkey. I used this book during my studies and it helped me so greatly.
