1/82. moraxella catarrhalis endocarditis: report of a case and literature review.

    A 53-year-old man developed severe acute systemic illness three weeks after an upper respiratory tract infection. Serial blood cultures grew moraxella catarrhalis. During antibiotic treatment, fever and infectious parameters disappeared, but severe aortic regurgitation developed. aortic valve replacement was performed, during which extensive destruction of the aortic valve was noted. endocarditis due to M. catarrhalis is very rare with, to our knowledge, only six cases having been reported to date. M. catarrhalis is a normal commensal of the upper respiratory tract, but in unpredictable circumstances can become an important pathogen. bacteremia due to this organism therefore requires prompt treatment, as serious organ complications, including endocarditis, can occur.

2/82. neisseria canis infection: a case report.

    The third case report, which is the first in australia, of human infection with neisseria canis is documented. This is the first case report in which the pathogenicity of this organism for humans is unequivocally demonstrated. ( info)

3/82. kingella kingae infections in children.

    OBJECTIVE: To increase awareness of kingella kingae infections in children by presenting four cases seen at the gold Coast Hospital, Southport, queensland, and reviewing the literature. METHODOLOGY: Records of the four cases were reviewed and relevant information described. A medline search of the English literature from 1983 to 1998 was conducted. RESULTS: Osteoarticular infections are the commonest type of invasive paediatric infection but bacteraemia and endocarditis also occur. Isolation of the organism is difficult but inoculation of the specimen into enriched blood culture systems improves the recovery rate. The majority of isolates are sensitive to beta-lactam antibiotics but resistance has been described. CONCLUSIONS: kingella kingae infections in children are more common than previously recognized. The organism should be actively sought in any child with suspected osteoarticular infections. Recommended empiric therapy is a third generation cephalosporin until susceptibility to penicillin is confirmed. ( info)

4/82. moraxella catarrhalis endocarditis: case report and review of the literature.

    A case of bacterial endocarditis caused by moraxella catarrhalis in an apparently immunocompetent Greek male is presented, which was diagnosed after a 2-month history of low-grade fever of unknown origin. The agent seems to be a rare pathogen, but due to the high mortality rate, it should always be considered in the differential diagnosis of relevant cases. Beta-lactamase production by many strains complicates the choice of antibiotic. ( info)

5/82. bacteremia and possible endocarditis caused by moraxella phenylpyruvica.

    moraxella phenylpyruvica, a gram-negative coccobacillus, is usually considered a nonpathogenic bacterium. Only a few cases of invasive disease caused by this organism were reported in the 1970s. We report a well-documented case of bacteremia and possible endocarditis due to M phenylpyruvica in a previously healthy man. ( info)

6/82. Obstructive airway disease caused by moraxella catarrhalis after renal transplantation.

    We report a case of severe acute obstructive airway disease 2 months after renal transplantation in a 16-year-old patient with Biedl-Bardet syndrome who was transplanted for end-stage renal failure secondary to cystic kidney disease. Symptoms of severe obstructive airway disease developed 2 months after transplantation under immunosuppression with prednisone, azathioprine, and tacrolimus. The patient did not develop signs of infection; progressive shortness of breath remained the only symptom for several weeks. After extensive diagnostic evaluation, bronchoalveolar lavage revealed moraxella catarrhalis as the single infectious agent. After 3 weeks of appropriate antibiotic therapy, symptoms of obstructive airway disease were completely relieved. This atypical presentation of moraxella infection in an immunocompromised host represents a rare complication of renal transplantation, especially in young patients. Special aspects such as frequency, diagnosis, differential diagnosis, and management of this rare complication of renal transplantation in a pediatric patient are discussed. ( info)

7/82. A case of moraxella canis-associated wound infection.

    moraxella canis was isolated from an infected foot ulcer in a patient suffering from diabetes mellitus with neuropathy. Bacteriological findings and 16S rDNA data are presented. ( info)

8/82. kingella kingae endocarditis in a sixteen-month-old-child.

    We report the case of a child with acute neurologic symptoms who was found to have bacterial endocarditis caused by kingella kingae. The case alerts microbiologists and pediatricians to an organism that has rarely been reported to cause endocarditis in children. ( info)

9/82. Soft tissue infection caused by kingella kingae in a child.

    During the last years an increasing number of reports concerning kingella kingae infections in children has been published. Most cases were osteoarticular infections. The authors report the clinical and laboratory findings from a 3-year-old child with a presternal soft tissue infection due to K kingae. After surgical excochleation and antibiotic treatment there was an uneventful recovery. J Pediatr Surg 36:946-947. ( info)

10/82. Clinical "pneumococcal pneumonia" due to moraxella osloensis: case report and a review.

    A previously healthy 6-y-old girl presented with a disease very similar to pneumococcal pneumonia. However, moraxella osloensis was isolated by lung tap. The patient responded well to a course of parenteral penicillin. This is probably the first documented case of community-acquired pneumonia associated with this agent. Clinical isolates of M. osloensis are rare and its pathogenesis has not been delineated; however, a literature review suggests that the organism is more common than is generally recognized. ( info)
