Question

Which is the first factor to consider in the presence of a fistulized anaerope apseiform infection with granules that resemble macroscopically sand grains that appear in the cervicofacial region after tooth extraction.
A)actynomyces israelii
B) nocardia brasiliensis
C)staphylococcus aureus
D)streptococcus pyogenes
E) pseudomonas aeruginosa

Answer 1

The option A is correct. Actinomycosis which cause multiple sinuses in cervicofacial environment , along with involvement of other organs. Both Nocardiosis and actinomycosis has lung, pulmonary involvement etc. Poor oral hygiene, dental trauma etc. , and slowly spread to face and other soft tissue . The induration slowly develops into inflamed sinuses. All are Gram positive organism but A and b are different class that possess charachter of fungi and bacteria as well. Actinomyces israyeli are important which forms fistules and inflammation in mucosal walls. The organism is anaerobe but others are aerobic. Nocardia is a bacterial genus under Actinomycetes which cause localised supportive lesion.
