MRI showed back soft tissue infiltration, posterior epiduritis, and infection of the L2 and L4 vertebral bodies Figure 5B. Cervicofacial actinomycosis is a relatively rare condition worldwide, with no predilection for age, race, season, or occupation. J Obstet Gynaecol Res. Pancreatic actinomycosis has been described in patients with pancreatic stents.

Actinomycosis axtinomicosis a quite common condition in cattle, where it is referred to as lumpy jaw or senfed moroccan arabicanimaled it can also occur in horsesswinedogs and rarely in sheep.

The use of semi-selective media such as phenylethyl alcohol or mupirocin-metronidazole blood agar may increase isolation rates by inhibiting overgrowth of concomitant organisms.


A year-old man with long-term tobacco and alcohol abuse was admitted for asthenia and loss of 20 kg in 6 months. Right radical nephrectomy was performed and the pathological examination of the specimen found actinomyces colonies.

Occurrence of BONJ is associated with duration of bisphosphonate therapy, concomitant use of corticosteroids, and mucosal disruption. Diagnosis can be difficult, and especially making a distinction between neoplastic conditions, malignant hemopathy, and other cervicofacial ne such as nocardiosis or mycobacterial infections.

Patients with actinomycosis require prolonged 6- to month high doses to facilitate the drug penetration in abscess and in infected tissues of penicillin G or amoxicillin, but the duration of antimicrobial therapy could probably be shortened to 3 months in patients in whom optimal surgical resection of infected tissues has been performed.

Actinomyces israelii is the most prevalent species isolated in human infections and is found in most clinical forms of actinomycosis.

Case 2 A year-old man with long-term tobacco and alcohol abuse was admitted for asthenia and loss of 20 kg in 6 months. 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. Simple culture of Actinomyces in BAL, as with sputum, is inappropriate for the diagnosis of pulmonary actinomycosis, except for patients with cavitation, as it may represent colonization.

Preventive measures animalws required to limit the occurrence of the disease. Actinomycosis IUD-associated infection is infrequent, but is clearly associated with the duration of the IUD use, hence it is recommended that an IUD be replaced every 5 years. Laboratory data often suggest infection but fever is not a frequent symptom 1.

Finally, clinicians should indicate suspicion for actinomycosis to the microbiologist to ensure that prolonged culture on appropriate media and animxles an appropriate atmosphere is performed.

A common method to achieve this is to give the cattle sodium iodide orally on a regular treatment schedule. The Actinomyces bacteria that cause lumpy jaw are always present in a healthy cattle’s mouth.

Its findings vary according to the stage of the disease and the region involved 1. Indeed, the diagnosis is crucial for an accurate diagnosis, by using specific culture media that allow the growth of Actinomyces spp. Microbiological diagnosis of actinomycosis The bacteriological identification of Actinomyces from a sterile site confirms the diagnosis of actinomycosis.

Retrieved from ” https: It is notable that surgery is not typically considered for treatment of cattle as it is in extreme human cases. Computed Tomography CT is the method of choice for evaluation of characteristics and extent of the process.
