RESUMO
Nontypeable Streptococcus pneumoniae is a common cause of epidemic conjunctivitis. A previous molecular fingerprinting study identified a clone of nontypeable pneumococcus that was responsible for a recent outbreak of conjunctivitis. In the present study, we examined the extent to which pneumococci that cause sporadic cases of conjunctivitis are related to this epidemic strain. Using arbitrarily primed BOX-PCR, we have determined that, of 10 nontypeable pneumococci causing sporadic conjunctivitis, 5 were clonal and closely related to a previous outbreak strain, whereas 5 others were genetically diverse.
