Ulcerative Stomatitis aka "mouth rot" is an infection of it's own and not caused by or necessarily related to upper respiratory infections.

There are a ton of bugs that have been associated with stomatitis in herps like A. aerophila, A. hydrophila, Proteus sp., Staphylococcus sp., and Streptococcus to name a few that I've seen.

Stomatitis is very often the result of poor husbandry which could also be the cause of a URI ... but one doesn't necessarily cause the other.

Hope this helps.
