* Title: Can the toxins affect the hostitself?

* Introduction: A toxin is a poisonous substance produced by living cells or organisms, they can be represented as a small molecule, peptides, or proteins, sometimes as a defensivelypathogen way. Toxins are elements that arise from the metabolic activity of bacteria could be inside the organism or in a medium. There are two principal types of toxins: endotoxin and exotoxin. Thefirst one is inside the bacterial cell and isn’t released until the dead of it. Otherwise the exotoxin is released during the life of the cell and most of the time present more toxicity. My thesis is toprove that a host can be affect by its toxin, for example a snake with its poison.

* Methodology: for this work I will use investigation from different sources such as Internet, books andmagazines, in order to prove the thesis statement. I also will use some interesting facts from discovery documentary.

* Results: Not been proven yet that the snakes are autoimmune to their ownpoison. There are several theories according to species. What is certain is that the poison is always kept in a gland, which sends it straight to the teeth and does not allow the poison to circulate throughthe body of the animal. "The question of are all snakes are immune to their own venom is not yet fully confirmed. But most certainly are". Then speaking of the immunity of a few species ofsnake venom of other snakes of different species. And finally add, that seems to refer to immunity by species, that is not poison herself or anyone else of the same species. Otherwise there is one bird that iscalled ifrita kowaldi, this is a special bird that is poisonous, because it eats a beetle with the same name that makes it grease the wings with the poison that produce the beetle. The problem is...
