• Fatigue

  […] tissue abscesses, or pus-filled lumps small holes or tunnels in tissue called fistulas that can leak a kind of lumpy pus The severity of symptoms mostly depends on where in the body the infection occurs There may be pain and fever, along with body aches, fatigue [medicalnewstoday.com]

• Sulfur Granules

  Direct spread into the adjacent tissues occurs over time, along with development of fistulas (sinus tracts) that discharge purulent material containing granules with a yellow sulfurlike appearance (termed sulfur granules). [emedicine.medscape.com]

  If the infection is present, the pus or tissue will usually contain yellow sulfur granules. In some cases, the abscess may resemble a cancerous growth. Lesions in the lungs can cause symptoms similar to cancer or tuberculosis (TB). [medicalnewstoday.com]

• Pneumonia

  […] of finding novel antibacterial compounds, this study aims to look for antibacterial compounds from rhizosphere actinomycetes against bacteria in urine of UTI patients (Escherichia coli, Citrobacter braakii, Acinetobacter calcoaceticus, and Klebsiella pneumoniae [smujo.id]

  In fact, pulmonary lesions, unless specifically suspected as actinomycosis, have a high probability of being mistakenly diagnosed as a neoplasm or a common form of pneumonia in the absence of a sinus tract [4]. [tandfonline.com]

  Methods: We present the case of a 35-year-old woman with a history of recurrent episodes of pneumonia. [mdpi.com]

  She had a medical history of scleroderma and interstitial pneumonia, which did not require steroid medication. The patient had undergone right mastectomy for right breast cancer (T4bN0M0, stage IIIB) and axillary lymphadenectomy 2 months prior. [jstage.jst.go.jp]

• Dental Abscess

  Common triggers include dental abscess or oral surgery. The infection can also affect certain women who have had an intrauterine device (IUD) to prevent pregnancy. [medlineplus.gov]

• Headache

  It can lead to a brain abscess, causing headaches and neurological symptoms. Another rare type affects the skin and bones, usually when the infection spreads from deeper tissues. Actinomycosis can take a variety of forms. [medicalnewstoday.com]

• Confusion

  This is one of the morphological reasons why acid-fast bacilli organisms such as Mycobacterium, Tsukamurella, and Rhodococcus may occasionally be confused even by experienced microbiologists by staining patterns.19,21,26 Therefore, filamentous branching [elsevier.es]

We were particularly interested in identifying those cases where Tsukamurella spp. or Rhodococcus spp. were isolated during the clinical workup of cases of presumed pulmonary TB. [elsevier.es]

Actinomyces infections (actinomycoses) are considered to be rare, however, due to the slow-growing and fastidious nature of these microorganisms, many Institutions do not have the capabilities or interest for their full diagnostic workup, therefore their [mdpi.com]

• Gram-Positive Bacteria

  Short description Actinomycetes are gram-positive bacteria, which are commonly found in nature. They produce interesting natural products, which are the basis of many of the antibiotics developed so far. [dzif.de]

  Members of the Actinomyces genus are non-spore-forming, anaerobic, and aerotolerant Gram-positive bacteria that are abundantly found in the oropharynx. [mdpi.com]

  Introduction Actinomycetales order mainly known as aerobic actinomycetes are Gram-positive bacteria with a high guanine-plus-cytosine (GC) content in their genomes1. [nature.com]

• Nocardia Asteroides

  Nocardia transvalensis NRRL B-10637 and Nocardia asteroides ATCC 19247 were served as control strains and incubated for 96 h for acceptable growth exhibition. [nature.com]

  The infectious causes include bacteria such as community-associated methicillin-resistant Staphylococcus aureus,3Actinomyces or Nocardia asteroids,1,2 Rhodococcus equi,4Pseudomonas aeruginosa,1 melioidosis,2 polymicrobial necrotizing pneumonias or lung [elsevier.es]

Full recovery can be expected with treatment. In rare cases, meningitis can develop from actinomycosis. Meningitis is an infection if the membranes covering the brain and spinal cord. This membrane is called the meninges. [medlineplus.gov]

It is important to get early treatment if it occurs. [medicalnewstoday.com]

The only deaths reported during the 6-month treatment period were the patients co-infected with Mycobacterium tuberculosis and Rhodococcus.19 Discussion In the presence of effective treatment, treatment failure of pulmonary TB is considered with continued [elsevier.es]

We emphasize the importance of early diagnosis, and delays in treatment can lead to increased morbidity and mortality. [bmcinfectdis.biomedcentral.com]

Prognosis When actinomycosis is diagnosed early and treated with appropriate antibiotic therapy, the prognosis is excellent. [emedicine.medscape.com]

Although the prognosis of Actinomyces infection is usually favorable under medical treatment, it can still lead to death in patients with extensive involvement or those without early detection. [bmcinfectdis.biomedcentral.com]

Other etiologies identified included nontuberculous mycobacteria: two cases of infection due to Mycobacterium kansasii and one case caused by Mycobacterium abscessus. [elsevier.es]

Actinomycoses are considered to be rare; however, reliable epidemiological data on their prevalence is lacking. [mdpi.com]

Precise identification of actinomycetes isolates using molecular-based approaches is required for a better understanding of the epidemiology of infection. [nature.com]

Epidemiology Frequency United States Actinomycosis is rare. During the 1970s, the reported annual incidence of actinomycosis in the Cleveland area was 1 case per 300,000 persons. [emedicine.medscape.com]

Pathophysiology Actinomycetes are prominent among the normal flora of the oral cavity but less prominent in the lower gastrointestinal tract and female genital tract. [emedicine.medscape.com]

The infection can also affect certain women who have had an intrauterine device (IUD) to prevent pregnancy. [medlineplus.gov]

Furthermore, the evaluation of the antibiotic resistance pattern of actinomycetes isolates should not be limited to a period of time and continuous monitoring is required for the prevention of infection and the improvement of therapeutic approaches. [nature.com]
