Right antibiotic is
Very importenat.The mortality at the original american legion convention in 1976 was high (34 deaths in 180 infected individuals) because the antibiotics used (including penicillins, cephalosporins, and aminoglycosides) had poor intracellular penetration.
Mortality has plunged to less than 5% if therapy is started quickly. Delay in giving the appropriate antibiotic
leads to higher mortality.
