Therefore, these bacteria form yellow colonies on XLD agar, but Salmonella spp. can decarboxylate lysin, which increases the pH and the colonies remain red. Furthermore, Salmonella spp. produce hydrogen sulfide (H 2 S) from thiosulfate, which results in a black precipitate with ferric salts.
Wisdom tooth extraction is performed with local anesthesia, IV sedation, inhalation sedation, or general anesthesia. In the US, the average cost of wisdom tooth extraction is $400 â $600. The average cost of a wisdom tooth extraction in Mexico is $150 â $250.
