Any of us or fish or mammals or its in some worms which come from a very Different Branch of the animal kingdom. Thats also interesting to those because those warms cause severe tropical diseases and if you kill all, you are able to kill the diseases, a different story. But yeah, a lot of biology that we dont understand. Why is it so good at jumping from host to host . Is it just because it spreads vertically throughout the population like i talked about with mosquitoes, is it also because its really good at jumping horizonly from one host to another. Maybe it gets infected by something. These are all questions theres actually a huge a thriving area of research. Still has a lot of unanswered questions. So weve so weve gone from cow poo to fecal transplants and back again. Thank you all for coming who are out of time. R i hope you all all come.
