An unusually severe and prolonged salmonella enteritis is described in 6 adults; 5 had previously undergone gastric surgery and one had pernicious anaemia. Possible causes are discussed but the probable common aetiological factor was deficient gastric juice. Hypo- or achlorhydric subjects appear more prone to salmonellosis and may become seriously ill as a result. Any diarrheal illness in them should be investigated by the bacteriologist before being attributed to altered physiology alone.
