These strains lack the capsule and are less invasive but cause localized infections.
This sketchy scene helps you remember: = chocolate agar, X+V factors, satellite growth, unencapsulated = mucosal, encapsulated = invasive (meningitis/epiglottitis/etc.), treat with ceftriaxone, prevent with Hib vaccine. h influenzae sketchy
In the Sketchy lesson , specific visual cues represent the biological requirements of the organism: These strains lack the capsule and are less
Remember: (Agar). It requires the treasure ( Factor X ) and a high five ( Factor V ). The dangerous Type B strain wears a B rimmed hat (Capsule) and causes Meningitis and Epiglottitis. The unencapsulated strain causes ear infections ( Otitis Media ). unencapsulated = mucosal
