1/38. 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.

2/38. 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.

3/38. 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.

4/38. 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.

5/38. 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.

6/38. 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.

7/38. bacteremia due to Moraxella atlantae in a cancer patient.

    A gram-negative alkaline phosphatase- and pyrrolidone peptidase-positive rod-shaped bacterium (CCUG 45702) was isolated from two aerobic blood cultures from a female cancer patient. No identification could be reached using phenotypic techniques. Amplification of the tRNA intergenic spacers revealed fragments with lengths of 116, 133, and 270 bp, but no such pattern was present in our reference library. Sequencing of the 16S rRNA gene revealed its identity as Moraxella atlantae, a species isolated only rarely and published only once as causing infection. In retrospect, the phenotypic characteristics fit the identification as M. atlantae (formerly known as CDC group M-3). Comparative 16S rRNA sequence analysis indicates that M. atlantae, M. lincolnii, and M. osloensis might constitute three separate genera within the moraxellaceae: After treatment with amoxicillin-clavulanic acid for 2 days, fever subsided and the patient was dismissed.

8/38. Isolation of Neissseria meningitidis from an unusual site.

    A 59-year-old post-menopausal lady who had returned from a pilgrimage to Mecca about a month earlier presented with a three days' history of profuse vaginal discharge. Neissseria meningitidis was isolated from high vaginal swab specimens taken from her on 2 occasions, five days apart. Her symptoms disappeared without treatment after two weeks. We conclude that although the organism may have been a colonizer, it is possible that it was responsible for the self-limiting genital infection in this patient.

9/38. Late-onset Moraxella catarrhalis endophthalmitis after filtering surgery.

    We describe a young man in whom endophthalmitis caused by Moraxella catarrhalis developed 5 years after glaucoma filtering surgery. The infection responded to treatment with broad-spectrum antibiotics, and 2 months after presentation the visual acuity had returned to 20/50. To our knowledge this is the first report of late-onset endophthalmitis due to M. catarrhalis complicating glaucoma filtering surgery.

10/38. An adult case of oral infection with kingella kingae.

    An exceptional case of microbiologically confirmed oral infection with kingella kingae in an immunocompetent adult (30-year-old woman) is presented and the pathogenesis is discussed and related to known literature data.K. kingae is a rather common but yet relatively unknown commensal corroding bacterium from the oro- and nasopharynx in healthy children, which might turn into a human pathogen causing osteomyelitis, arthritis, spondylitis, endocarditis and intervertebral diskitis in young children and rarely endocarditis, septic arthritis, meningitis, epiglottitis, diskitis and bacteraemia in adults. Sofar K. kingae associated stomatitis was reported in children and a few adults, however, with concomitant herpes simplex virus infections, and without microbiological confirmation. In the described case no viral infection was found. The proven K. kingae stomatitis represents an extension of the pathogenic spectrum and suggests that the breach of the oral mucosal barrier can be caused by the bacterial pathogen itself. Whether a concomitant viral infection is necessary forK. kingae to actually invade the bloodstream remains to be considered.
