Nasal carriers with purulent skin lesions or respiratory viral infections have been described as being especially apt to transmit staphylococci1 , 2; yet carriers lacking these conditions have also been observed to cause considerable environmental contamination and to spread infection to contacts.3 Carriers whose nasal swabs yielded 105 or more Staph. aureus organisms in broth have been reported by White4 to disperse more of these organisms to the air and . . .
