INFECTIONS WITH MULTIPLE SALMONELLA TYPES, INCLUDING S. BRAENDERUP

Abstract
In January 1950, at the Halloran Veterans Administration Hospital, there occurred a small outbreak of Salmonella infection, involving mainly the intestinal tract. Seven types of Salmonella were eventually recovered from 20 patients. In 10 of these, two or three separate types were found. As the sequence of events became increasingly complicated, it became clear that several epidemiological problems would remain unanswered. This outbreak was, however, considered worthy of report in order (1) to emphasize the difficulty in disentangling the epidemiological sequences in even a small outbreak in a localized, controlled area, (2) to report the isolation in 9 cases of S.braenderup, a species heretofore unreported in the western hemisphere, and (3) to report briefly a few experiences with chloramphenicol (chloromycetin®) treatment. REPORT OF SALMONELLA OUTBREAK On Jan. 9, 1950 several cases of diarrhea appeared among patients in the communicable disease ward of this hospital. Close questioning of all ward personnel
