Abstract

Female pelvic actinomycosis may involve fallopian tubes, ovaries, uterus and bladder. This condition is often associated with the use of intrauterine contraceptive devices (IUDs), vaginal pessaries and/or tampons. The predominant causative agent of human actinomycosis is Actinomyces israelii, which has been found on copper IUDs retrieved from patients. In this work, a biofilm of A. israelii was developed in vitro on copper surfaces immersed in a simulated uterine fluid under anaerobic conditions. The biofilm was characterized using scanning electron microscopy (SEM), energy dispersive X-ray and atomic force microscopy. The capacity of A. israelii to develop a biofilm over copper surfaces in synthetic media was demonstrated. SEM micrographies illustrate the exopolysaccharides production and bacterial distribution. A. israelii was able to attach and grow in synthetic intrauterine media and to present on the copper surface is likely due to the production of biofilm.

Actinomycosis

Actinomycosis is a rare, chronic, and slowly progressive granulomatous disease caused by filamentous Gram positive anaerobic bacteria from the Actinomycetaceae family (genus Actinomyces). The disease is characterised by the formation of painful abscesses in the mouth, lungs,breast or gastrointestinal tract. Discover the latest research on actinomycosis here.

Biofilm & Infectious Disease

Biofilm formation is a key virulence factor for a wide range of microorganisms that cause chronic infections.Here is the latest research on biofilm and infectious diseases.
