“…The biofilm was spongy and porous and allowed ion interchange between the solution and the copper surface, thereby maintaining the corrosion process active in localized zones where the metal undergoes pitting. In past reports (Valdez et al , 2003a, b), the main corrosion products were related to Cu(I) species in the form cuprous oxide and hydroxide according to the results yield by cyclic voltammetry analysis. Nevertheless, Cu(II) took relevant importance when the biofilm was detached from the IUD surface after seven days exposure.…”

PurposeColonies of Actynomyces israelii bacteria have been found in removed copper intra‐uterine devices (IUD) used as a long‐term contraceptive method. The purpose of this paper is to characterize the biofilm developed under anaerobic conditions by Actynomyces israelii on IUD surface, and its influence in the copper corrosion processes.Design/methodology/approachThe dissolution of copper on the intra‐uterine cavity prevents conception because of the toxic effect of the ions released. Nevertheless, microbiological growths have been detected on the IUD devices retired after long periods of insertion. In order to know about the influence of the biofilm on the corrosion of copper, electrochemical, spectroscopic and surface analysis techniques were applied to study the phenomenon.FindingsA porous Actynomyces israelii biofilm was formed on the copper IUD surface. The bacteria colony had developed in an exopolimeric substrate, which protects it from the toxic effect of copper ions. The corrosion process was not inhibited by the biofilm, due to the pores present which permit the transport of species through them.Practical implicationsThe results of this study show that there is no decay in the contraceptive function of the IUDs due to the presence of a bacterial biofilm on its surface.Originality/valueThe relationship between microbial colonization and the corrosion process of copper IUD under anaerobic conditions was characterized. These results will complement previous investigations performed on the study of corrosion of copper IUDs under different conditions.

“…A synthetic uterine solution was prepared in demineralized water according to the same formulation utilized in a previous work for the aerobic conditions (Valdez et al , 2003b). The aqueous solution contains 0.072 g/l NaH 2 PO 4 .2H 2 O, 4.97 g/l NaCl, 0.224 g/l KCl, 0.167 g/l CaCl 2 , 0.25 g/l NaHCO 3 and 0.50 g/l glucose.…”

AbstractMicrobiologically induced corrosion of copper intrauterine devices "TCu380A" and "Nova T" by Enterobacter sp. in a synthetic intrauterine medium was investigated. The corrosion behaviour was evaluated applying cyclic voltammetry and Tafel Polarization. The surface morphology was determined using scanning electron microscopy, the corrosion products were analyzed using energy dispersive X-rays and the biofilm composition was examined by Fourier transform infrared spectroscopy with an attenuated total reflectance device.
