Bacillus anthracid And Cereus-King Antra's Axe Flashcards
What is the result of gram staining Bacillis Anthracis and cereus
Gram positive
What does the lesion caused by Bacillis Anthracis look like
Black Escher with erythematous ring (black middle surrounded by a red ring)
What does Bacillis Anthracis look like under a microscope
Large gram positive rods in a chain
What is the state of the capsule in Bacillis Anthracis
Protein capsule
What is the protein capsule in Bacillis Anthracis made of
Poly D glutamate
What is the state of oxygen susceptibility of Bacillis Anthracis
Obligate aerobe
What allows Bacillis Anthracis to survive in very poor environments
Spore forming
What are the two toxins produced by Bacillis Anthracis that are required for symptoms
- EF toxin
- LF toxin (lethal factor)
What is the result of EF toxin produced by Bacillis Anthracis
Causes edema by increasing cAMP intracellularly, inhibiting host defenses and phagocytosis
What is the result of LF toxin produced by Bacillis Anthracis
Exotoxin that acts as a protease to cleave MAP kinase, leading the necrosis and black eschar
What is wool sorters disease caused by Bacillis Anthracis
Spores get into wool and animal hides. People inhale the spores and develop pulmonary anthrax
What is the serious complication that develops with Bacillis Anthracis
Pulmonary anthrax can develop to hemorrhagic mediastianitis (about 100% mortality rate)
What is the X ray finding during an infection with Bacillis Anthracis
Widened mediastinum
What are the treatments for Bacillis Anthracis
Doxycline (bike wheel shield in picture)
Flouroquinolone (flower shield)
What are the characteristics of the Bacillis Cereus
Aerobic, spore forming gram positive
What is the common method of transmission for Bacillis Cereus
Reheating fried rice
