Why is Gonorrhea So Hard To Fight?

Описание: While it might not be sexy to talk about STIs, it’s worth taking a look at how these persistent infections well, persist in their hosts. The pathogens that cause STIs have adapted their own unique set of tools used to evade detection and deletion by the immune system. And Gonorrhea is a top contender for the most manipulative. It turns out, the G in “Gonorrhea” stands for “Gaslight”
