Answer

Streptococcal pyoderma may occur in children belonging to certain population groups and in overcrowded institutions. The modes of transmission are direct contact, environmental contamination, and houseflies. The strains of streptococci that cause pyoderma differ from those that cause exudative tonsillitis.
