Trichinella Skin Tests in an Orphanage and Prison. Comparison With Serologic Tests for Trichinosis and With the Tuberculin Reaction 1

The Effect on the Trichinella Skin Test of Simultaneous Infection With Bovine Tuberculosis in Trichinous Rabbits 1

“…It was noted that a higher percentage of positive reactions to trichinella antigen (18.3 per cent) was obtained in 674 patients with active tuberculosis in 3 sanatoria, than in 335 patients without tuberculosis (7.2 per cent) in 2 general hospitals (1). The explanation for this phenomenon has not been found by investigations on the possible effects of institutionalization and sensitization by the ingestion of nonviable trichinae (2,3). The possibility of a biologic cross reaction, detectable by skin test, between Mycobacterium tuberculosis and Trichinella spiralis was investigated in guinea pigs infected simultaneously with tuberculosis and trichinosis (4).…”
