Presented is the case of a 62-year-old man with refractory shock secondary to copper sulfate ingestion. The patient's history was complicated by the presence of peptic ulcer disease, myocardial disease, and a known abdominal aortic aneurysm. Despite the presence of such characteristic signs and symptoms as hemorrhagic gastroenteritis, hemolytic anemia, and refractory hypotension, the diagnosis of copper sulfate ingestion was delayed for several days after ingestion, when the family first volunteered that the patient had vomited blue-green material the day before his admission to the hospital. This delay contributed significantly to the patient's ultimate demise.

Salmonellae most commonly cause uncomplicated cases of gastroenteritis but have a predilection for damaged blood vessels, especially those damaged by atherosclerosis. The abdominal aorta is most frequently affected. The most serious complication of aortitis is mycotic aneurysm formation with subsequent rupture. The authors present the case of a 61-year-old man who was found unresponsive at home 3 days after discharge from the hospital for treatment of gastroenteritis with bacteremia. Postmortem examination revealed a ruptured mycotic aneurysm with a large retroperitoneal hematoma. Numerous gram-negative rods were embedded in the wall of the aorta and surrounding inflammatory infiltrate, compatible with the patient's previously isolated. Whereas abdominal aortic aneurysm rupture is most commonly associated with atherosclerosis, the isolation of from blood cultures, coupled with radiographic evidence of gas surrounding the aorta, should raise the suspicion of infectious aortitis. Whereas fatal rupture of an aortic aneurysm secondary to atherosclerosis alone or in conjunction with aortitis will not have an impact on the manner of death, infections are reportable and thus have public health implications.

Nontyphoidal salmonellae are among the most common causes of bacterial gastroenteritis worldwide. They are also notable causes of extraintestinal infections, including bacteremia and vascular infections. Salmonella enterica serotype Choleraesuis is typically associated with invasive infections. We report a patient who had an infected intra-abdominal aortic aneurysm due to an unusually mucoid strain of Salmonella enterica serotype Choleraesuis. The isolate was erroneously identified as Hafnia alvei by the Vitek GNI+ card system. A blood culture isolate taken from the same patient 9 months earlier was also identified as H. alvei by the Vitek GNI+ card system. Despite an apparent cure with intravenous amoxicillin-clavulanic acid at that time, the Salmonella infection had not been cleared and manifested as a ruptured infected abdominal aortic aneurysm. Repeated passage of the strain yielded nonmucoid colonies, which were correctly identified by the API and PHOENIX systems. The isolates from the aneurysm and the former bacteremic episode were found to be identical using pulsed field gel electrophoresis. The fallibility of automated bacterial identification systems is highlighted. Such errors are especially important for isolates in which in vitro antibiotic susceptibility testing does not correlate with the clinical success of treatment, as illustrated by Salmonella infections.

Each year, 1.4 million people in the United States are infected with Salmonella (Beneson et al. [23] Am J Med, 110:60-63, 2001). The most common clinical presentation of Salmonella infection is gastroenteritis which is usually self-limited, lasting between one to four days (Black et al. [24] N Engl J Med, 261:811-816, 1960). Although most infections are mild-to-moderate, serious disease, and death does occur (Voetsch et al. [25] CID, 38:S127-S132, 2004). A rare but increasing number of patients present with Salmonellosis spondylodiscitis resulting from contiguous spread of infection from the adjacent abdominal aorta. Concurrent infection of these structures exacerbates morbidity, necessitating an elevated clinical suspicion in patients with appropriate risk factors, clinical signs and symptoms. Furthermore, an overall mortality rate of 67% makes mycotic abdominal aortic aneurysms highly lethal (Gonda et al. [26] Radiology, 168:343-346, 1988). Thus, early diagnosis is crucial, allowing for prompt antibiotic and surgical management. Laboratory and imaging tests obtained at the initial suspicion for infection of the spine and aorta facilitates diagnosis while minimizing or preventing more serious complications like paresis and aortic rupture. We present a patient with a mycotic abdominal aortic aneurysm infected with Salmonella enteritides that spread to the adjacent lumbar vertebra and left psoas muscle.
