Group B streptococci in women fitted with intrauterine devices
Abstract:
A survey was made of group B streptococcal carriage at various sites in 100 women attending a clinic for the insertion of an intrauterine contraceptive device (IUD). Twenty-three women carried streptococci at one or more sites at the preinsertion visit, the vaginal carriage rate being 16%. Six months after insertion changes in carrier status were noted and there was evidence of a change of strain in four patients. Twenty-nine women were carriers at one or more sites at some stage of the study. There was no evidence that symptoms attributable to infection in patients fitted with an IUD were caused by group B streptococci.

Factors Affecting the Risk of Infection
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...
