Bacteriological Profile and Antimicrobial Susceptibility Pattern of Cervico-Facial Cellulitis at the Regional Teaching Hospital of Ouahigouya (Burkina Faso)

Context and Objective: Cervicofacial cellulitis is a lethal infection without treatment. The aim of this study is to establish the bacteriological and antimicrobial susceptibility profile of cervico-facial cellulitis at the Regional Teaching Hospital (RTH) of Ouahigouya, in order to guide practitioners in the development of effective probabilistic antibiotic therapy protocols. Subjects and Methods: This was a transversal descriptive study with prospective data collection from July 1 to December 31, 2021 at the RTH of Ouahigouya. All cases of suppurative cervicofacial cellulitis that had been the subject of pyoculture were retained. Results: A total of 63 patients were chosen including 41 men, with 40.91 years as the average age and the sex ratio was 1.86. In 90.48% of cases, the front door was dental. All patients took antibiotics before their admission. Pus culture was positive in 34/63 subjects (53.97%) and showed monomicrobial infection. The isolates were Gram-negative bacilli for 20.59% and Gram-positive cocci for 79.41%. These isolates were all resistant to certain beta-lactams (such as amoxicillin, amoxicillin + clavulanic acid). However, some isolates were susceptible to cefoxitin, ceftazidime and ceftriaxone. All isolates were sensitive to amikacin for aminoglycosides. As for macrolides, erythromycin had excellent activity (100%) against Gram-positive cocci. Indeed, some isolates were susceptible and others resistant to ciprofloxacin for quinolones. Conclusion: Bacteriological profile and antimicrobial susceptibility knowledge of cervicofacial cellulitis may propose an effective probabilistic antibiotic therapy protocol.
