Question

the name of the infection that produces a chronic inflammatory reaction and \pus\ that contains yellow \sulfur granules\ is which of the following?
candidiasis
scarlet fever
aphthous stomatitis
actinomycosis
vincents angina

Explanation:

Actinomycosis is a chronic suppurative (pus - forming) infection. The pus in actinomycosis often contains yellow "sulfur granules" which are aggregates of the Actinomyces bacteria.
Candidiasis is a fungal infection (usually caused by Candida species) that presents with symptoms like white plaques (in oral candidiasis) or vaginal itching and discharge (in vaginal candidiasis), not sulfur granules.
Scarlet fever is a streptococcal infection characterized by a red rash, fever, and a "strawberry tongue", not sulfur - granule - containing pus.
Aphthous stomatitis (mouth ulcers) are painful, round or oval ulcers in the mouth, with no relation to sulfur granules.
Vincent's angina (acute necrotizing ulcerative gingivitis) is a bacterial infection of the gums with symptoms like bleeding gums, bad breath, and ulcerated gums, not sulfur granules.

Answer:

Actinomycosis
