Hi, wow, where to start? I guess you have to think what is strange? Some might be considered strange because they live in crazy places like salt pools, deserts or poluted land. Others are strange in the way they can keep changing their antigens so they look different to our immune system each day (like we change our clothes). Some are strange in that they can change our mind, like syphilis and brucellosis infections can make you go mad! What there is no shortage of is variety 🙂
