Abstract
Cellulites of dental origin are extensive polymicrobial infections of the face and neck cell-adipose tissues. Management of infections of this nature presents significant challenges. The key to this is the identification of the causative organisms and determination of their susceptibility to antibiotics. Enterococcus and Aerococcus are pathogenic and opportunistic bacteria. Despite their low virulence, these microorganisms are responsible for many human infections. A major problem with these bacteria is their frequent multidrug resistance. The lack of data on these bacterial strains involved in the cellulite in Burkina Faso thus justifies the choice of Enterococcus and Aerococcus. This study was therefore undertaken to determine bacterial etiologies and antibiotic resistance profiles associated with cellulites cases in Ouagadougou, Burkina Faso. A total of 62 samples from patients were analyzed. The isolates were obtained using conventional microbiology procedures. Strains were identified by using API 20 Strep (bioMerieux, France). Antibiotic susceptibility and detection of extended spectrum β-lactamases (ESBLs) were performed according to the European Committee of Antimicrobial Susceptibility Testing (EUCAST). The patients were 41.9% males and 58.1% females. Aerococcus was isolated from 30 patients and Enterococcus from 7. Aerococcus strains were resistant to metronidazole (100%), cefixim (93.3%), trimethoprim-sulfamethoxazole (86.7 %), oxacillin (83.3%), penicillin G (83.3%), cefotaxime (80%), chloramphenicol (80%), cefuroxime (76.7%) and to ceftriaxone (76.7%). Enterococcus strains were resistant to metronidazole (100%), cefixim (100%), cefotaxim (100%), ceftriaxone (100%), cefuroxime (100%), trimethoprim-sulfamethoxazole (100%), penicillin G (100%), oxacillin (100%) and to amoxicillin (100%). Only one Aerococcus viridans strain was positive for ESBL production (2.7%). The emergence of resistance among the bacterial strains that have been implicated in odontogenic infections is a public health issue in Burkina Faso that warrants a significant degree of concern.
Highlights
Pathologies with a dental origin often result in infectious complications, which can be local, regional, or general
Oral Aerococcus and Enterococcus may be a potential reservoir for the transferable elements of virulence and antimicrobial resistance [14,15]; severe cellulitis typically involves microbial virulence with the presence of multi-resistant germs
The present study aimed to determine the prevalence and antimicrobial susceptibility of Enterococcus and Aerococcus strains involved in these infections, in order to better prevent them
Summary
Pathologies with a dental origin often result in infectious complications, which can be local, regional, or general. The high incidence of infectious complications represents a significant public health issue that is all the more unacceptable given that effective prevention is generally within reach [1] These types of infections are frequently associated with poor oral hygiene [2,3,4]. The oral cavity provides ideal conditions for microbial growth (i.e. the right humidity, temperature, etc.), and the flora is a combination of aerobic and anaerobic bacteria. These are often nonpathogenic commensal organisms, some, such as Streptococcus, Peptostreptococcus, Bacteroides, etc. The present study aimed to determine the prevalence and antimicrobial susceptibility of Enterococcus and Aerococcus strains involved in these infections, in order to better prevent them
