COMPARATIVE STUDIES OF DIPHTHERIA CULTURES OF LOEFFLER'S MEDIUM WITH THE ORIGINAL SWABS TRANSPORTED BY MAIL.
Swabs and cultures prove to be of equal value for diphtheria diagnosis while swabs may give evidence of other infections. This paper tells of an experiment in routine work lasting a year. It shows swabs to be less costly, never dry through storage, and better for surveys. The paper emphasizes the need of rural branch laboratories.
