Diagnosis of Clinical and Subclinical Salmonellosis by Means of a Serologic Hemagglutination Test

Abstract

ALTHOUGH extraordinary advances in sanitation and other control measures of infectious diseases have been made during the present century in many countries, salmonellosis, other than typhoid fever, still contributes substantially to morbidity, particularly in children and debilitated persons. Recently, several authors^{1 2 3 4} reviewed their experiences with this malady. Saphra and Winter¹ analyzed data on 7779 human infections; gastroenteritis was present in 68.3 per cent, and carriers accounted for 15 per cent. Eisenberg et al.² observed among 75 bacteriologically proved cases of salmonellosis an over-all fatality rate of 20 per cent, and a rate of 5.3 per cent from the infection itself. . . .
