Endocarditis caused by Actinobacillus actinomycetemcomitans.
Actinobacillus actinomycetemcomitans is a gram-negative coccobacillus which is a very rare cause of bacterial endocarditis. Preexisting cardiac lesions are a main contributing factor, and antibiotic prophylaxis has long been felt necessary before dental or other manipulation to prevent endocarditis. Penicillin in combination with an aminoglycoside has been the most often used treatment regimen....
متن کاملSubacute bacterial endocarditis due to Actinobacillus actinomycetemcomitans.
A case of infective endocarditis in a 59-year-old female caused by Actinobacillus actinomycetemcomitans is reported. The organism was recovered from 9 blood cultures. Despite treatment with penicillin and gentamicin the illness led to destruction of the aortic valve.
متن کاملFailure of vancomycin prophylaxis and treatment for Actinobacillus actinomycetemcomitans endocarditis.
Reported is a case of Actinobacillus actinomycetemcomitans endocarditis which developed after dental prophylaxis with vancomycin and erythromycin. In vitro results indicated that this isolate and 20 additional isolates were resistant to vancomycin and that potentially useful bactericidal antibiotics for the prophylaxis and treatment of A. actinomycetemcomitans infections included gentamicin, su...
متن کاملCharacterization of serologically nontypeable Actinobacillus actinomycetemcomitans isolates.
Our previous studies have shown that Actinobacillus actinomycetemcomitans isolates of a given arbitrarily primed PCR (AP-PCR) genotype belong to the same serotype (of serotypes a through e). In the present study we investigated whether the AP-PCR genotypes of nonserotypeable A. actinomycetemcomitans isolates match those of the serotypeable isolates. The isolates were additionally characterized ...
متن کاملSecretion of RTX leukotoxin by Actinobacillus actinomycetemcomitans.
Actinobacillus actinomycetemcomitans, the etiologic agent for localized juvenile periodontitis and certain other human infections, such as endocarditis, expresses a leukotoxin that acts on polymorphonuclear leukocytes and macrophages. Leukotoxin is a member of the highly conserved repeat toxin (RTX) family of bacterial toxins expressed by a variety of pathogenic bacteria. While the RTX toxins o...
