Why are burns more prone to infection than lacerations or abrasions?

I was under the impression that the biggest threat with a burn is infection, why is that?

Depending on how serious the burn is, it can destroy the skin to various depths. Thus opening the barrier that was there to keep infections away (notice how permeable your skin becomes at the burn site, it usually becomes shiny and wet as your plasma leaks out). Burns tend to have a bigger surface area than the other two wounds, and also harder to close through blood clotting and sabbing.

I think if you have a large and serious abrasion wound, it'd be similar to a burn wound in terms of the effect.
