Swabs from 112 removed intrauterine contraceptive devices (IUCD), endocervical swabs from these women and from 65 women with pelvic inflammatory disease (PID) were studied for actinomyces, using direct fluorescent antibody test and culture. Endocervical swabs from 50 control subjects were also studied. Actinomyces species could be detected in 23 (20.5 percent) of IUCD wearers and 8 (12.3 percent) of patients with PID. In control cases, no actinomyces were detected. The isolation rate using a selective medium (Actino Blood Agar) was 71.4 percent. Actinomyces israelii, Actinomyces naeslundii and Actinomyces viscosus were isolated.

Researching disinfection strategies is pivotal because effectively eliminating bacteria and their byproducts during root canal treatment (RCT) remains a challenge. This study investigated the antimicrobial efficacy of natural antimicrobial compounds, propolis (PRO) and copaiba oil-resin (COR), compared to conventional agents in Endodontics. Antimicrobials were tested against endodontic pathogens via macrodilution with standardized inoculums to determine the minimum inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC).

Minimal Access Surgery, King's College Hospital NHS Foundation Trust, London, GBR.
Actinomycosis is a chronic, granulomatous infection caused by species, a group of anaerobic, gram-positive bacteria commonly found in the human oral cavity, gastrointestinal, and female genital tracts. Although it predominantly affects the cervicofacial region, rare manifestations such as gallbladder actinomycosis can occur. This report presents a case of gallbladder actinomycosis in a 61-year-old man who presented with a two-week history of right upper quadrant pain, jaundice, nausea, and vomiting.
