The role of adhesion in the migration of bacteria along intrauterine contraceptive device polymer monofilaments

Abstract

Abstract Using an in vitro model simulating the female genital tract, it was demonstrated that bacterial adhesion to intrauterine contraceptive device (IUD) tails is of importance in the transmission of bacteria along such surfaces. The process of bacterial adhesion to polymer monofilaments was subsequently investigated. Organisms were seen to adhere reversibly at first and then to produce polymeric material to achieve stronger, irreversible adhesion. Using scanning electron microscopy, the extent of bacterial adhesion was shown to be dependent upon several factors including the bacterial species and the microrugosity of the threads. A greater number of bacteria were found adhering to the monofilaments when there was no agitation of the washing or dehydrating solutions compared to the standard preparatory techniques.
