Actinomyces are commensals of the human oropharynx, and are particularly prevalent within gingival crevices, tonsillar crypts, periodontal pockets and dental plaques, as well as on carious teeth.

Respiratory tract actinomycosis includes pulmonary, bronchial, and laryngeal actinomycosis. The gold standard for diagnosing pulmonary actinomycosis is histological examination and bacterial culture of a lung biopsy, obtained by percutaneous biopsy guided by CT scan or by open surgical resection.

Right nephrectomy was performed. The classification of Actinomyces spp. Consequently, actinomycosis is mainly considered an endogenous infection that is aniimales by a mucosal lesion. Author information Copyright and License information Disclaimer.

Discussion Actinomycosis is a chronic granulomatous infection with a worldwide distribution 1. Am J Med Sci. Epidemiology and pathogenesis A.

Case 4 A year-old woman with past history of breast cancer was admitted 7 years after radiotherapy for left mandibular metastasis with left mandibular pain, buccal-sided bone exposure, and sinus tract Figure 4.

Pediatr Infect Dis J. Specific preventive measures reduction of alcohol abuse, dental hygiene, change of IUD every 5 years may limit the occurrence of actinomycosis. Mabeza GF, Macfarlane J. Surgery should be discussed in complicated cases, but the cornerstone of treatment is prolonged antimicrobial therapy with a beta-lactam such as penicillin or amoxicillin.

In the genitourinary tract, actinomyces can cause primary renal infection 1,2,5,6including a horseshoe kidney 7reno-duodenal fistula 8 and reno-colic fistula 9. Cervico-facial actinomycosis; etiology and diagnosis.

Diagnosis As Actinomyces spp. Of note, in any site, actinomycosis frequently mimics malignancy, tuberculosis, or nocardiosis, actinomicksis it spreads continuously and progressively, and often forms a cold abscess. Diagnosis The diagnosis is mainly based on stereotaxic aspiration of pus, revealing Actinomyces spp.

Primary skin and soft-tissue actinomycosis is poorly described. Heymann, American Public Health Association, Aggregates of Actinomyces spp.


Neovascularization and chronic right renal vein thrombosis without evidence of active bleeding was demonstrated in selective angiography Figure 3. Panoramic dental X-ray shows mandibular lucencies C. Disseminated infection due to Actinomyces meyeri: The most appropriate clinical specimens are tissue from surgical biopsy or pus; swabs must be avoided.

In typical cases, ie, especially in patients with lumpy jaw syndrome, Actinomyces spp. Pathological examination of the specimen shows fibroadipose tissue and a mix of acute and chronic inflammatory reaction with areas of fibrosis and granulation tissue.

Indeed, the diagnosis is crucial for an accurate diagnosis, by using specific culture media that allow the growth of Actinomyces spp. The latter may facilitate Actinomyces colonization and invasion of the jaw, as Actinomyces spp. Antimicrobial therapy is the main treatment for genitourinary tract actinomycosis. Enhancement of experimental actinomycosis in mice by Eikenella corrodens. Contrast-enhanced magnetic resonance image of the left ear of a patient with an abscess arrow due to Actinomyces spp.

Actinomycosis in animals

Diagnosis Women carrying an IUD for over 5 years and presenting with a pelvic mass have a high index of suspicion for IUD-related actinomycosis. Concerning laryngeal actinomycosis, various different forms have been described.

Although most cases of actinomycosis occur between 15 and 35 years of age, there are cases described in children under 10 years of age. Susceptibilities of Actinomyces species and Propionibacterium propionicus to antimicrobial agents.

In all achinomicosis species, actinomycosis results in cold abscess, with granulomatous formations on the fistulised place. Empyema necessitatis due to Actinomyces odontolyticus. Few case reports have been described in the literature.

Actinomycosis: etiology, clinical features, diagnosis, treatment, and management

Clinical features of actinomycosis Respiratory tract actinomycosis Epidemiology and pathogenesis Respiratory tract actinomycosis includes pulmonary, bronchial, and laryngeal actinomycosis. A tubo-ovarian abscess strongly suggests pelvic actinomycosis, whereas some patients present with radiological findings suggesting malignant tumors. The affected areas are treated with iodine solutions. Growth of Actinomyces is slow; it appears within at least 5 days and may take up to 15—20 days.

Bronchoscopy should be performed to exclude malignancy. Oostman O, Smego RA. Abdominal computed tomography scan showing peritoneal effusion and heterogeneous pelvic mass surrounding an intrauterine device Awith abscesses B corresponding with pelvic actinomycosis. Abstract Actinomycosis is a rare chronic disease caused by Actinomyces spp. The main CT findings are consolidation, lymph node enlargement, atelectasis, cavitation, ground glass opacity, and pleural effusion.

Microbiological diagnosis of actinomycosis The bacteriological identification of Actinomyces from a sterile site confirms the diagnosis of actinomycosis.

Fluoroquinolones ciprofloxacin and moxifloxacin are usually considered to be inactive, but data are limited and controversial. A new form of presentation of renal actinomycosis:
