Abstract
The authors discuss the value and need for Salmonella typing in public health laboratories and the typing methods used in the Connecticut laboratories are presented. A public health laboratory should render at least a minimum typing service by which human types may be differentiated from animal types and the main somatic groups may be recognized. The methods involved are no more complicated than those for pneumonia. The results of the Salmonella service in Connecticut extending over a period of 45 months are given. 435% of all new Salmonella isolations were of animal origin, 56.7% of human origin. The most common types were typhi, 40.8%; schottmuelleri, 15.9%; and typhimurium, 145%. The carrier state in man was rarely prolonged with the animal strains either in convalescents or healthy individuals-and the chronic carrier state is by no means so frequently found as the types of human origin. The antigenic analysis of Salmonella cultures is the only procedure by which the laboratory can furnish an authentic report and thus save time and effort in ensuing epidemiological investigations.
