Dysbiosis of human tumor microbiome and aberrant residence of Actinomyces in tumor-associated fibroblasts in young-onset colorectal cancer

Frontiers in Immunology, 2022
Colorectal cancer (CRC) is the third most common form of cancer, and the incidence of sporadic young-onset colorectal cancer (yCRC) has been increasing. Microbiota residing in the tumor microenvironment are emerging tumor components.

The Pathogenic Role of Actinomyces spp. and Related Organisms in Genitourinary Infections: Discoveries in the New, Modern Diagnostic Era

Antibiotics, 2020
Actinomycosis is a chronic, suppurative, granulomatous infectious disease, caused by different species of Actinomyces bacteria. To date, 26 validly published Actinomyces species have been described as part of a normal human microbiota or from human ...

Bacterial Endocarditis Caused by Actinomyces oris: First Reported Case and Literature Review

Journal of Investigative Medicine High Impact Case Reports, 2020
Actinomyces species are gram-positive, facultative anaerobic bacilli. Infection caused by Actinomyces species is usually limited to cervicofacial, thoracic, and abdominopelvic regions.

Prevalence of Bacteria of Genus Actinomyces in Persistent Extraradicular Lesions—Systematic Review

Journal of Clinical Medicine, 2020
Actinomyces are anaerobic, rod-shaped, Gram-positive bacteria. They are associated with persistent extraradicular endodontic infections, with possible involvement of the soft tissues of the maxillofacial district.

Microbial Association with Genus Actinomyces in Primary and Secondary Endodontic Lesions, Review

Antibiotics, 2020
The main reason for root canal treatment failure is the persistence of microorganisms after therapy, or the recontamination of the root canal system due to an inadequate seal. In the mouth, Actinomyces spp.

Actinomyces and Alimentary Tract Diseases: A Review of Its Biological Functions and Pathology

BioMed Research International, 2018
Actinomyces are nonmotile, filamentous, Gram-positive bacteria that cause actinomycosis in immunodeficiency patients. Although the prognosis of actinomycosis is good, the diagnosis of actinomycosis is quite difficult. Recent studies on actinomycosis have
