Actinobacillus actinomycetemcomitans fimbriae

Oral Microbiology and Immunology, 1988
Freshly isolated Actinobacillus actinomycetemcomitans strains were found to possess fimbriae. These appendages appeared to be irreversibly lost after 30 to 40 subcultures in the laboratory. The fimbriated strains were associated with a specific type of colonial morphology designated SP (Star Positive); the non‐fimbriated variant colony was designated ...

Actinobacillus prosthetic valve endocarditis

American Heart Journal, 1989
Actinobacillus actinomycetemcomitans is a slow-growing, fastidious, capnophilic gram-negative rod that is a rare but recognized cause of both native and prosthetic valve endocarditis.

Endothelial cytotoxicity of Actinobacillus pleuropneumoniae

Research in Veterinary Science, 1991
The cytotoxicity of Actinobacillus pleuropneumoniae serotype 1 strain CM5 for porcine and bovine endothelial cells in vitro, was dose-dependent. This strain and its attenuated and avirulent substrain CM5A were equally cytotoxic. The cytotoxicity observed during five hours of exposure of endothelial cells to bacterial products was abolished if the ...

Actinobacillus actinomycetemcomitans Infection

Clinical Infectious Diseases, 1989
There are no medical restrictions placed upon admission, which, therefore, is unselected, being based solely upon the severity of the illness as judged by the admitting physician. We certainly agree with the assertion of Guerin et al. that the incidence of underlying disease and sources for the bacteremia and the mortality are likely to vary with the ...

Hemolysin patterns of Actinobacillus pleuropneumoniae

Journal of Clinical Microbiology, 1990
The secreted hemolytic activities produced by the reference strains and field isolates of the 12 serotypes and 2 subtypes of Actinobacillus pleuropneumoniae were analyzed. Serotype 1 produced a Ca2(+)-inducible hemolysin, which was previously characterized as a 105-kilodalton protein and was named hemolysin I (HlyI).

Actinobacillus actinomycetemcomitans Prosthetic Valve Endocarditis

Clinical Infectious Diseases, 1988
Actinobacillus actinomycetemcomitans, a fastidious gram-negative bacillus, has been reported as the cause of prosthetic valve endocarditis in 11 patients. Two additional patients are reported and the literature is reviewed. All cases occurred greater than 1 year after implantation of the prosthesis.

Endocarditis Caused by Actinobacillus actinomycetemcomitans

Southern Medical Journal, 1979
A case of endocarditis caused by Actinobacillus actinomycetemcomitans is described and 18 cases are reviewed. Clinical features of endocarditis caused by A actinomycetemcomitans and antibiotic susceptibility are reviewed. Because of the relative resistance of A actinomycetemcomitans to penicillin and ampicillin, high doses of either penicillin or ...

Inducible bacteriophages of Actinobacillus actinomycetemcomitans

Current Microbiology, 1995
Doses of 0.1 to 1.0 micrograms/ml of mitomycin C induced cell lysis of six of eight strains of Actinobacillus actinomycetemcomitans tested. Infectious phages were induced from ATCC strains 43717, 29524, 33384, and 43719; non-plaque-forming, possibly defective phages were induced from ATCC strains 29522 and 29523.

[Actinobacillus actinomycetemcomitans endocarditis].

Harefuah, 1993
Bacterial endocarditis caused by Actinobacillus actinomycetemcomitans (AA) is an extremely rare disease. AA, a gram negative cocco-bacillus, normally resides in the oral cavity. It is involved mostly in local oral cavity infections, but severe systemic infections caused by it have been reported. We describe a 63-year-old man with endocarditis caused by

Actinobacillus actinomycetemcomitans endocarditis.

Canadian Medical Association journal, 1978
Two patients had infective endocarditis due to Actinobacillus actinomycetemcomitans. One, a 52-year-old woman with a prosthetic aortic valve, was successfully treated with carbenicillin and gentamicin. The other, a 47-year old man with calcific aortic valve disease, required emergency valvectomy and prosthetic valve replacement and responded to a ...
