ESLAVA, CAMILO et al. UNCOMMON SEVERE ODONTOGENIC FACIAL CELLULITIS CAUSED BY AMPCPRODUCING CITROBACTER FREUNDII IN A PATIENT WITH TYPE 2 DIABETES MELLITUS. CASE REPORT. rev.fac.med [online]. 2012, vol.20, n.1, pp.35-41. ISSN 0121-5256.

The management of odontogenic facial cellulitis is still a controversial issue in the field of Oral and Maxillofacial Surgery. Surgical and therapeutic principles have undergone modifications based on clinical findings, imaging and microbiological over time. In patients with type 2 Diabetes Mellitus the risk of opportunistic bacterial infections is increased thus suffering longer hospitalization periods than the nondiabetic population. The literature is clear by setting the clinical and microbiological differences of odontogenic facial cellulitis in this group of patients, but there is no surgical medical protocol for them. Klebsiella pneumoniae is the most common microorganism isolated while Citrobacter freundii is unusual in relation to oral infections; their ability to produce ESBLs (AmpC) allows them to block the action of empirical antibiotics used in Maxillofacial Surgery. We present the case of a 61 year old patient with type 2 Diabetes Mellitus and odontogenic facial cellulitis caused by AmpCproducing Citrobacter freundii.
