<prompt> All of the following are true about bacillus anthrax except -Plasmid is responsible for toxin productionCutaneous anthrax generally resolve spontaneouslyCapsular polypeptide aids virulence by inhibiting phagocytosisToxin is a complex of two fractions  <response>: Ans. is d i.e., Toxin is a complex of two fractions VIRULENCE FACTORS OFANTHIRA BACILLI 1 Capsular polvpeptide -inhibits phagocytosis - encoded by a plasmid 2 Anthrax toxin -is a complex of three fractions : a The edema factor EF or factor I It is an adenyl cyclase, leading to intracellular accumulation of cAMP Responsible for the edema b The protective antigen factor PA or factor II binds to the receptors on target cells antibody to PA is protective c The lethal factor LF or factor III Causes cell death Mechanism is not known - Anthrax toxin is encoded by a separate plasmid. About option b . Cutaneous antrax generally resolves spontaneously, but 10-20 of untreated patients may develop fatal septicemia or meningitis.
