Salmonella Bacteremia in an Older Patient With No Specific Entry: A Case Report

Abstract

In this case report, we describe a rare case of non-typhoidal Salmonella bacteremia in an 87-year-old woman with no apparent history of daily Salmonella exposure. The patient presented with fever, body discomfort, and diarrhea. Medical examinations ruled out usual sources of Salmonella , including raw food consumption and pet contact. Her medical history included postoperative sigmoid colon cancer, left breast cancer, and other ailments. Although Salmonella infection typically stems from oral intake, this case suggests that bacterial translocation from the gastrointestinal tract could be the primary cause, potentially exacerbated by the patient's age and medical history. Another hypothesis is an ascending infection from diarrhea to the urinary tract, which might have led to pyelonephritis and subsequent bacteremia. This case highlights the importance of recognizing the potential for severe infections such as sepsis in older individuals presenting with diverse symptoms. Therefore, this case further underscores the need for heightened clinical vigilance, especially in community hospitals, to ensure timely and appropriate management of such severe conditions in the older population.
