title: An unusual organism causing orbital cellulitis.
abstract: Bacterial orbital cellulitis is a feared complication of paranasal sinus infection. Staphylococcus and Streptococcus species are the commoner pathogens involved in these cases. However, anaerobic bacteria and unusual Gram-negative organisms should be suspected as well. We treated a case of bacterial orbital cellulitis due to foci of infected paranasal sinuses caused by Eikenella corrodens, a Gram-negative rod. The patient was managed with intensive antibiotic coverage and surgical intervention.
