BACKGROUND, AIMS The purpose of the present study was to compare and relate the microbial composition of supra and subgingival plaque in 23 adult periodontitis subjects (mean age 51 +/- 14 years). METHODS A total of 1,170 samples of supra and subgingival plaque were collected from the mesial aspect of every tooth (up to 28 supra and 28 subgingival samples) from each subject and evaluated for ...

Here, we report the main characteristics of Actinomyces urinae strain Marseille-P2225(T) (CSURP2225) isolated from a human urine sample.

Crohn disease is a chronic inflammatory condition that primarily affects the gastrointestinal tract. Typical manifestations include fever, weight loss, fatigue, and abdominal pain, and abdominal abscesses and fistulae are frequent complications. Abdominal actinomycosis is a subacute or indolent disease associated with Actinomyces spp. Symptoms can be very similar to those of Crohn disease, and ...

Actinomyces israelii is an uncommon cause of upper genital tract infection. This gram-positive anaerobe is occasionally noted on the Papanicolau smear of asymptomatic patients utilizing the intrauterine device. In this case, a 57-year-old woman presented with postmenopausal vaginal bleeding. A Pap smear showed filamentous microorganisms consistent with Actinomyces israelii (A). Despite a negati...

Purified cell walls of Actinomyces viscosus and Actinomyces naeslundii were solubilized by the enzymatic action of Ml N-acetylmuramidase. Soluble cell wall carbohydrate antigens were purified by column chromatography. A purified antigen preparation (fraction C) from A. viscosus ATCC 19246 was found to contain deoxyhexoses (rhamnose and 6-deoxytalose), hexosse (galactose, glucose and mannose), a...

Eighty-five strains of bacterial species selected from the predominant cultivable dental plaque flora of patients with different periodontal pathologies were examined for their plasmid content. Microorganisms studied included: Actinomyces viscosus, A. odontolyticus, Bacteroides asaccharolyticus (B. gingivalis), B. melaninogenicus subspecies intermedius, and subspecies melaninogenicus, Capnocyto...

background and purpose: cutaneous infections arise from a homogeneous group of keratinophilic fungi, known as dermatophytes. since these pathogenic dermatophytes are eukaryotes in nature, use of chemical antifungal agents for treatment may affect the host tissue cells. in this study, we aimed to evaluate the antifungal activity of actinomyces species against trichophyton mentagrophytes (abbrevi...

This case contemplates the unusual presentation, challenging diagnostic workup and conservative therapeutic process of a patient with Actinomyces empyema complicated along way due to drug reaction eosinophilia systemic symptoms (DRESS) syndrome. The was 40-year-old male, who presented pleurodynia fever. Laboratory exams showed elevated inflammatory markers imaging revealed two biconvex fluid po...
