"IF MSC students Measures BP of B.Anthrax, they are utilizing energy to form AMP...."

B.Anthrax------
- Inverted fir tree appearance
- Frosted glass appearance
- Medusa head colony
- String of pearl's reaction
- Cut glass appearance in transmitted light
- Milzbrand-bazillus
- Bamboo stick appearance
- Polyglutamate capsule
- Ascoli's thermoprecipitin test
- M'Fadyean's reaction
- PLET Medium

Pulmonary anthrax----- by inhalation of wool----- so, "wool sorter's disease"

Cutaneous anthrax----- most common---painless ('hidden') charbon---- so, "hide porter's disease"
