title: Relative efficacy of blood, urine, rectal swab, bone-marrow, and rose-spot cultures for recovery of Salmonella typhi in typhoid fever.
abstract: The recovery of Salmonella typhi from blood, rectal swab, urine, bone-marrow, and rose spots was compared in 62 patients with typhoid fever, most of whom had received some antibiotic therapy before presentation. S. typhi was isolated from culture of bone-marrow in 56 patients (90%); in contrast, S. typhi was recovered from blood in only 25 (40%), from stool in 23 (37%), and urine in 4 (7%). S. typhi was isolated from 24 (63%) of 38 patients who had rose-spot cultures. If culture sites had been limited to blood, stool, and urine, the bacteriological diagnosis would have been missed in 24 patients.
