a

S. aureus isolates with the indicated agr specificity group among households where transmission was not apparent (only one family member was colonized, or family members were colonized by unrelated S. aureus strains).

b

S. aureus isolates implicated in staphylococcal transmission in families.

c

P value comparing the number of agr specificity groups in the nontransmitting isolates to the number of agr specificity groups in the transmitting isolates by Fisher's exact (two-tailed) test.
