While I was pondering what to do about this, Ron Ritzman restored it as a contested PROD, and then Dragonfly67 deleted it again saying "Although there do appear to be antimicrobial polypeptides in crocodile blood, there isn't really any serious research that uses this name. Sorry.." I don't really disagree with either of those decisions, but after pondering further I have restored the article and moved it into the Article Incubator at WP:Article Incubator/Crocodillin. I think with Dr. Britton's help there probably is an article here, but it will not in the end be called "Crocodillin" (a) because that term is not a well enough established neologism to satisfy WP:NEO and (b) in order not to give aid and comfort to persons who are apparently peddling quack medicines using the term. I have protected the title "Crocodillin" as an interim precaution. Dr. Britton, I will email you some links and suggestions of how you can help.
