Comparing an adult boa with an adult gabon viper is a lot different. The fangs on a gabon will do a lot more damage and could potentially carry bacteria that once it penetrates so deep in your tissue, it "could" cause a bad reaction. However, a cobra vs a boa or a coral snake vs a ratsnake? what do you really think the answer is? Of course NOT. There is no difference getting bitten by a venomoid coral snake or a non-venomous kingsnake. If anyone tells you that a venomoid's snakes bite carries more bacteria than other snakes, they are full of crap.
