Scientists in Germany have reported that persistent infection with chlamydia, may cause cancer, by causing mutations on the host DNA and by inhibiting attempts by the host to repair the damage.

Chlamydia is the most common STI, infecting over 90 million people across the globe every year. It is often asymptomatic and can persist for many years unnoticed, and is a leading cause of infertility. It is also increasingly becoming harder to treat due to antibiotic resistance,further contributing to persistent infection.

There is growing evidence that chlamydia can cause changes to host cell DNA , which in turn is implicated in development of a range of cancers such as cervical and ovarian cancer.

Not only does evidence point to chlamydia changing host cell DNA but it also seems to inhibit the repair mechanisms that would usually kick in the cause the s it so cells to die . This means that the damaged DNA was passed on causing more abnormal cells, which is a hallmark of cancer

It is important to realise that this is only one study and more research is needed before we make too many assumptions , but its definitely food for thought!
