Peritonitis is one of the most frequent complications in peritoneal dialysis (PD) patients. Most of them have a bacterial origin, especially gram-positive microorganisms. Actinomyces peritonitis is rare in PD patients, in spite of being part of the normal flora in the oral cavity, gastrointestinal and genital tracts [1]. Actinomyces is a filamentous gram-positive bacterium that lives in aerobic...

Three cases of brain abscess caused by Actinomyces israelii are reported which were successfully treated by burr hole aspiration and a short course of antibiotics (3-4 weeks). The clinical response of the patients, as well as the serial serum C-reactive protein levels and CT findings were used as a guideline for stopping antimicrobial therapy relatively early.

Nude (Nu/Nu) and heterozygous (NU/+) mice were infected with Actinomyces israelii serotype I by either intranasal instillation or intravenous injection. Lung clearance data and 50% lethal dose values indicated that T-lymphocytes were not necessary for pulmonary clearance or prevention of systemic actinomycosis. However, T-lymphocyte deficiency may play a role in the localized cervicofacial form...

Actinomycosis is a chronic granulomatous disease caused mainly by Actinomyces israelii. It is characterized by formation of multiple draining sinuses with discharge of characteristic yellow sulphur granules. There am five clinical types depending on the primary site of infection, namely cervicofacial, thoracic,, abdominal, primary cutaneous and pelvic. Primary cutaneous actinomycosis is very un...

Actinomycosis is a slowly progressive infection caused by anaerobic bacteria, primarily from the genus Actinomyces. Primary actinomycosis of the breast is rare and presents as a mass like density which can mimic malignancy. Mammography, ultrasonography and histopathologic examination is required for diagnosis. Treatment should consist of high doses of antibacterials for a prolonged period of ti...

Actinomyces is a Gram-positive, filamentous bacterium that normally colonizes mucosal areas. Pelvic actinomycosis is a chronic granulomatous disease caused by Actinomyces israelii that frequently mimics ovarian tumors during presentation. It is diagnosed after surgery in most of the cases. Intravenous penicillin is the most preferred therapeutic agent, and it requires hospitalization up to one ...

In order to compare the degradation of PLA composites by different microorganisms, and reveal mechanism. Actinomyces israelii, Aspergillus niger, Trichoderma harzianum Phanerochaete chrysosporium were selected degrade composites. The weight loss, functional groups, thermal properties crystallinity before after analyzed. results indicated that A. israelii niger had strongest ability composites, ...

Actinomycosis is a very rare disease caused by Actinomyces israelii, saprophytic bacterium of the oropharynx and genital tract women. Its diagnosis made difficult lack clinical radiological specificity. We report three cases patients with actinomycosis various locations, but similar management. These recall radio-clinical therapeutic aspects this infection. They underline necessity microbiologi...

Crossed immunoelectrophoresis (CIE) with intermediate gel was applied to the serological analysis of Actinomyces israelii to develop a test with high efficiency in the laboratory diagnosis of human actinomycosis and classification of A. israelii. Recently developed standard antigen-antibody systems for A. israelii by CIE were used as reference. The reference systems were based on standard prepa...
