A child presented with otitis media. The suspected organism is Hemophilus influenzae. All are TRUE about H. influenzae, EXCEPT:

The polyribose phosphate capsule of type b H influenzae is the major virulence factor. H influenzae was the most common cause of bacterial meningitis in children age 5 months to 5 years. H influenzae is differentiated from related gram-negative bacilli by its requirements for X and V factors and by its lack of hemolysis on blood agar. Also know: H influenzae does not grow on sheep blood agar except around colonies of staphylococci ("satellite phenomenon"). H influenzae does not produce exotoxin.
