Cell surface structures of Actinomyces israelii.
Actinomyces israelii is the most common cause of human actinomycosis, a chronic granulomatous infection. Periapical actinomycosis involving A. israelii has been identified as an important cause of failure of conventional endodontic treatment. Structures on the bacterial cell surface have been implicated in the pathogenicity of Actinomyces. In this study the ultrastructure of A. israelii was inv...
متن کاملComparative pathogenicity of Actinomyces naeslundii and Actinomyces israelii.
Typical actinomycosis has been produced in mice following single intraperitoneal injections of saline suspensions of Actinomyces israelii and A. naeslundii. A. israelii produced infections in 95.8% of the animals inoculated. A. naeslundii, generally considered to be a saprophytic organism, produced lesions in 89.7% of the inoculated animals. The finding that A. naeslundii produced lesions in mi...
متن کاملPrimary Sternal Osteomyelitis Caused by Actinomyces israelii
Primary sternal osteomyelitis is a rare disease. Common infectious organisms causing primary sternal osteomyelitis include Staphylococcus aureus and Pseudomonas aeruginosa. Actinomyces species are common saprophytes of the oral cavity, but there have been few reports in the literature of primary sternal osteomyelitis caused by Actinomyces species. We describe a case of primary sternal osteomyel...
متن کاملActinomyces israelii: a rare cause of thoracic empyema.
Actinomyces israelii usually causes chronic suppurative and granulomatous infections. Isolated pleural effusion due to Actinomycosis is rare. This report describes an unusual case of thoracic empyema caused by A. israelii with sudden onset and rapid deterioration that failed to respond to chest tube drainage and antibiotherapy. Empyema drainage and visceral parietal pleurectomy by a left postol...
متن کاملActinomyces israelii in the female genital tract: a review.
Actinomyces israelii (a gram-positive, branching, anaerobic or microaerophilic bacterium) infects 1.6-11.6% of IUD users worldwide. Physicians must decide whether to treat A. israelii infection with antibiotics, remove the IUD, or refer the patient to the family planning clinic. Culture techniques tend to be inadequate, so many US health professionals use a microscope to identify A. israelii ...
