I brewed my third batch today and was very careful with sterilization (or so I thought). Less than 5 hours after pouring the wort into the carboy, I noticed this on the inside of the carboy, right on the very top of the carboy opening. Is this an infection? If so, can the batch be saved? Sorry for the quality on the pictures.

I did my best to wipe off what appeared to be bacterial colonies. I’m worried, however, that this just led to further infection. Any help would be appreciated.
