“…1 Staphylococcus aureus, Nocardia species, Actinomadura madurae, and some Streptomyces species may produce colonies resembling sulfur granules (Figure 3 and Figure 4). 3 Diagnosis is made by identifying branching filament colonies. 2 Special staining and anaerobic culture techniques help confirm diagnosis since cultures are positive in only 24% of cases 2 ; diagnosis is often based on histopathologic findings.…”

14-YEAR-OLD girl had severe, sharp midback pain for 3 weeks and nontender, gradually enlarging left chest wall swelling for 2 weeks. It was unrelieved by change of position. One month before symptoms started, she had fallen, striking her left chest. No bruise remained and the tenderness subsided; however, 2 weeks later, swelling began in the area of injury. She had lost 10 pounds over the last 2 months while dieting. She had no fever, cough, chills, sweats, joint pain, or rash. Last year, she lost a filling from a right upper molar, but otherwise, her last dental care was 6 years ago. She was receiving 325 mg of ferrous sulfate per day for iron deficiency anemia diagnosed 1 month earlier. Findings from physical examination revealed an obese female (height, 139.7 cm; weight, 83.3 kg). Her temperature was 38.5°C; pulse, 120 beats per minute; respirations, 20 breaths per minute; and blood pressure, 122/88 mm Hg. Spinal examination showed scoliosis but no vertebral or costal tenderness. A 4-cm mass was palpated over the left rib cage at the anterior axillary line in the 10th interspace. This mass was ovoid, nontender, soft, and cool to the touch without erythema. A large cavity was present in the upper left molar.

“…are abundantly present in the normal flora of humans (especially in the oral microbiome), these infections are mainly endogenous [5,14]. Actinomycoses infections of an exogenous source or interpersonal transmission were not been reported, apart from so-called “punch or knuckle” actinomycosis, corresponding to punching or biting injuries [55].…”

Similarly to other non-spore-forming Gram-positive anaerobes, members of the Actinomyces genus are important saprophytic constituents of the normal microbiota of humans. Actinomyces infections are considered to be rare, with cervicofacial infections (also known as ‘lumpy jaw syndrome’) being the most prevalent type in the clinical practice. Actinomycoses are characterized by a slowly progressing (indolent) infection, with non-specific symptoms, and additionally, the clinical presentation of the signs/symptoms can mimic other pathologies, such as solid tumors, active Mycobacterium tuberculosis infections, nocardiosis, fungal infections, infarctions, and so on. The clinical diagnosis of actinomycosis may be difficult due to its non-specific symptoms and the fastidious, slow-growing nature of the pathogens, requiring an anaerobic atmosphere for primary isolation. Based on 111 references, the aim of this review is to summarize current advances regarding the clinical features, diagnostics, and therapy of cervicofacial Actinomyces infections and act as a paper for dentistry specialists, other physicians, and clinical microbiologists.

Ac.ti.no.my'ces. Gr. fem. n. aktis, aktinos ray; Gr. masc. n. mukês fungus; N.L. masc. n. Actinomyces ray fungus referring to the radial arrangement of filaments in Actinomyces bovis sulfur granules. Actinobacteria / Actinobacteria / Actinomycetales / Actinomycetaceae / Actinomyces Straight or slightly curved rods , 0.2–1.0 µm in diameter, which vary considerably in shape and size, and slender filaments , 1 µm or less in width and 10–50 µm or more in length, with true branching. Short rods (0.5–5.0 µm in length) with or without clubbed ends are frequently seen and may occur singly, in pairs with diphtheroidal arrangements (Y, V, T forms and palisades), in short chains or in small clusters. Longer (5.0–10.0 µm in length) branched rods are also common. Several members of the genus appear chiefly or exclusively as coccobacillary or even coccoid elements. Filaments which may predominate in certain species are either straight or wavy , show varying degrees of branching and may have swollen, clubbed, or clavate ends. Gram‐stain‐positive , but irregular staining giving rise to a beaded or barred appearance frequently occurs, and two species may be Gram‐stain‐variable. Non‐acid‐fast, nonmotile, and non‐endospore‐forming. Conidia are not produced. DNA G+C content (mol%) : 55–71 ( T m , HPLC). Type species : Actinomyces bovis Harz 1877, 133 AL .
