Final answer:
The infection associated with sulfur granules in the cervicofacial region is Actinomycosis, typically caused by Actinomyces israelii.
Step-by-step explanation:
The infection associated with sulfur granules in the cervicofacial region is Actinomycosis. Actinomycosis is a chronic bacterial infection that is often caused by Actinomyces israelii. This infection can lead to the formation of abscesses, and sulfur granules can be seen in the pus from these lesions. These granules are actually clusters of the bacteria and are not made of elemental sulfur, despite the name. Sulfur granules are a distinctive feature of Actinomycosis, which helps differentiate it from other infections such as tuberculosis, syphilis, and histoplasmosis. It commonly affects the cervicofacial region and can cause symptoms such as swelling, pain, and draining sinus tracts.
