Anyone know anything about black-throated monitor lizards?

Asked about a particular study where someone got bitten at a zoo here in the US on the foot.

I do not know the specifics about that case and of course i am not a physician but speculation that artery or tendon damage could cause complications or additional surgeries, or a secondary infection seem most probable for extended stay. Large teeth causing deep lacerating wounds, anticoagulant properties of saliva and possibility for introduction of bacteria all account for dangerous bite from a komodo. The point is moot however, a bite is dangerous from any large animal. Any animal including dragons host bacteria in their mouth, but it has been ruled conclusively that rotting meat between teeth causing death by bacterial infection in animals bitten by komodos has been ruled out, they have no more higher amounts of bacteria or more deadly strains than other animals sampled, a more likely source of infection and resultant deadly sepsis is when injured, the animals (wild cattle) retreat to mud water holes that have large quantities of the animals' own urine and fecal material in them.

Here is a zoo keeper bitten story where Dr. Bryan Fry (venom doc) talks about Komodos being venomous (anticoagulation properties)

This is the zookeeper bite

yeah the foot bite seems to have resulted in surgery

So these three bites in captivity actually just sound like regular monitor bites, with maybe the exception of the one where the bleeding couldn't be controlled. But then there was also this bite that occurred recently to someone well-known in the lizard community: https://www.youtube.com/watch?v=gmn4GGQaVuc. It's a bite from his monitor. This is the monitor that did it: https://www.youtube.com/watch?v=HtUB4d0CH_8. So not even very big.

Hey, wanted to come and add what I've learned over the years here about venom.

So, the new definition of venom would make monitors venomous. Komodos are indeed venomous lizards. So by the new definition, I stand corrected.

One of the big things that scientists are pushing for right now is: "Just because it's venomous, doesn't mean it's dangerous." Example: Garter snakes are venomous, and they don't hurt humans at all, but they do have venom specialized for their prey. So scientists are trying to change the stereotypes about venom. Some scientists are very resistant to the change in definition, but this is the way science is going, so they'd better get on board--or at least have some sound articles/research backing up their outdated claims. Some do have good arguments, but they are in the minority. So my friend--although very well-educated on the venom discussion--is currently wrong (as science currently stands).

As for iguanas being venomous, it's actually super interesting. They possess atrophied (no longer do what they were originally intended to do, or underdeveloped) venom glands. I would have to do research on which species if not all have them.

It is proposed that snakes, monitors, and iguanas possess venom or venomous components to some degree.

Here's a couple articles and snippets to read from if you're interested in learning more.

***Here is Fry's article that started it all.***

Here's an article that shows some opposition. New school vs Old school, you could say.
