Endocarditis due to Listeria monocytogenes is rare with only 13 cases cited in the world's literature. We report an additional case with a review of the previously reported patients. In contrast to other clinical forms of listeriosis, endocarditis does not tend to occur in patients with severe underlying disorders or those on immunosuppressive regimens. Listeric endocarditis has a predilection for left-sided cardiac involvement (100 percent), and systemic embolization is a major clinical feature (58 percent). Prognosis of listeric endocarditis is unfavorable and the mortality rate (43 percent) exceeds that for bacterial endocarditis with more common pathogens (23 percent). Antibiotic sensitivity data suggest that ampicillin or penicillin may be the chemotherapeutic agents of choice.

Listeria monocytogenes is an uncommon cause of mycotic aneurysms, endocarditis, and other endovascular infections. When they occur, these infections usually involve patients with relatively normal host defenses, but with abnormal vascular intima or cardiac valves. We have reported a Listeria monocytogenes infection at the site of a posttraumatic aortic aneurysm.

Many discriminative experimental animal models of infection have been utilized in the evaluation of newer fluoroquinolones. In vivo efficacy of many of the newer agents has been shown in experimental models of meningitis, endocarditis, pneumonia, urinary tract infections, pyelonephritis, osteomyelitis, abscesses of various types, septic arthritis, gastroenteritis, salmonellosis, listeriosis, tuberculosis, syphilis, sinusitis, prostatitis and burn wound sepsis, among others. This review focuses on recent developments in a few selected areas. Although the limitations of animal model studies are well described, these results provide a rationale for the appropriate clinical usage of the newer fluoroquinolones in humans.

Although resistance to Listeria monocytogenes infection requires intact T cell-mediated immunity, only 20 patients with human immunodeficiency virus (HIV) infection and listeriosis (including one patient described herein) have been reported to date. Listeriosis developed before AIDS in five cases. Syndromes included meningitis in nine cases, bacteremia in nine, brain abscess in one, and endocarditis in one. Eighteen patients were treated with ampicillin, penicillin, or amoxicillin with or without aminoglycosides. Clinical and microbiologic responses were obtained in one patient with bacteremia treated with vancomycin and in one patient with meningitis treated with trimethoprim-sulfamethoxazole. Three of the nine patients with meningitis died, as did the patient with brain abscess. All nine patients with bacteremia and the patient with endocarditis survived. No case of relapse was documented. L. monocytogenes, although uncommon, should be considered in the differential diagnosis of febrile illness, meningitis, and brain abscess in patients with HIV infection.

Although listeriosis is an uncommon infection in patients with human immunodeficiency virus (HIV) infection, the frequency of listeriosis in New York City has increased because of the increase in the number of HIV-infected patients. The medical records of 30 patients admitted to three medical centers in New York City from 1981 to 1988 with infections due to Listeria monocytogenes were reviewed. Six patients had AIDS, one was seropositive and asymptomatic, and four had risk factors for HIV infection. While the annual number of cases of listeriosis in patients without risk factors for HIV infection was constant, 9 of the 11 patients with AIDS or with risk factors for HIV infection presented with listeriosis between 1985 and 1988, the last half of the survey period. These patients were male homosexuals or intravenous drug abusers, and all but one were black or Hispanic. Manifestations of listeriosis in patients with AIDS or with risk factors for HIV infection included bacteremia without apparent source in seven, meningitis in three, and endocarditis in one, syndromes that were similar to those in patients without risk factors for HIV infection. Ten of 11 patients were treated with penicillin or ampicillin, and 7 were also given an aminoglycoside. All patients responded well to therapy and no relapses were observed. Physicians should include antibiotics effective against L. monocytogenes when treating AIDS patients with meningitis of unknown origin and consider the diagnosis of listeriosis in patients with sepsis of unknown origin.

A study was made of 92 bacteremia episodes among patients admitted to the Ivrea-Castellamonte Hospital (Turin, Italy) between June 1986 and September 1989. A single microorganism was isolated in 84 episodes (91.3%), the most common being: Staphylococcus aureus (21.7%), Escherichia coli (18.5%), Enterococcus (9.8%), Pseudomonas aeruginosa (6.5%), and Proteus mirabilis (5.4%). The episodes were of both hospital and community origin: 54.3% vs. 45.7%. Their main sources were: the urinary tract (16.3%), abdominal infections (14.2%), endocarditis (7.6%), and the respiratory tract (5.5%). No source could be identified in 26%. Brucellosis, salmonellosis and listeriosis together constituted 8.7% of the episodes. Abdominal infections were primarily responsible for the 8 cases (8.7%) of polymicrobial bacteremia. The overall mortality was 18.5% (6.5% community vs. 12% hospital episodes). Mortality directly due to bacteremia was 8.7%. Bacteremia was the direct or indirect cause of death in 22.6% of patients greater than or equal to 65, compared with 19% and 10% in those aged 35-64 and 15-44 respectively. The patient's clinical picture at the time of infection was a prognostic factor: mortality was much lower in subjects previously healthy or free from basic diseases (11.8%) than in those with non-rapidly-fatal diseases (21.7%) or rapidly-fatal diseases (54.5%). Bacteremia-linked mortality (direct and indirect) was higher in Gram-positive vs Gram-negative infections: 22.2% vs 15.8%. Mortality was 12.5% in the group of patients with polymicrobial infections.

Endocarditis due to listeria monocytogenes is rare with only twenty one cases to our knowledge appearing in the world's literature to date. We report a further case with a successful surgical outcome and stress the importance of surgery in the treatment of infective endocarditis. There is a clear predilection of this organism for the left side of the heart and systemic embolization is frequent. In contrast to other clinical forms of listeriosis, endocarditis has not been associated with debilitating states or immunosuppressive treatments. Though clinical and laboratory data suggest a similarity with other types of bacterial endocarditis, the prognosis is more unfavorable and the mortality rate higher.

Penicillin allergy presents a major obstacle to the successful management of some antepartum infections. We studied 15 pregnant women with histories of penicillin allergy confirmed by positive immediate wheal-and-flare skin tests. Thirteen had syphilis, one listeria sepsis, and one Streptococcus viridans endocarditis. Each patient was desensitized over four to six hours by oral administration of increasing doses of penicillin V. At the completion of the procedure, full-dose parenteral therapy with penicillin G or ampicillin was instituted. No extracutaneous reactions were detected. Five of the subjects (33 per cent) experienced pruritus (three) or urticaria (two), but no interruption of desensitization or therapy was necessary. All clinically apparent maternal infections were cured. The pregnancy complicated by listeriosis aborted in the first trimester. The 11 neonates delivered to date are normal. These results indicate that oral desensitization is an acceptably safe approach to therapy in pregnant women who are allergic to penicillin and have infections that require beta-lactam drugs.

A man died in endocarditis due to listeriosis in the late autumn. He had been looking after two goats during the summer. Listeria monocytogenas was isolated from a rectal swab from one of the goats. The goat faeces isolate and the human blood isolate were of identical serovar. The two isolates, however, were shown to be different by multilocus electrophoretic enzyme analysis and ribotyping, as well as by biotyping. Thus, these results do not support the hypothesis that the man was infected by the goat.

Listeria monocytogenes has long been known as a pathogen of immunocompromised hosts, including solid organ and bone marrow transplant recipients. Its principal manifestations include bacteremia and meningitis. Endocarditis due to Listeria is far less common and in general affects the left side of the heart. We here report an unusual case of Listeria tricuspid valve endocarditis and septic pulmonary emboli in a sulfa-intolerant liver transplant recipient with a history of relapsing cytomegalovirus (CMV) hepatitis and an indwelling Hickman catheter. The literature on Listeria endocarditis and infections in transplant recipients is reviewed. The possible relationship between susceptibility to Listeria infection and the discontinuation of trimethoprim-sulfamethoxazole prophylaxis is of interest.
