Background: Infections due to Staphylococcus sciuri in hospitalized patients seem to be emerging in different
countries. Their incidence and clinical impact with inpatients have not been studied in Benin.
Objective: The aim of this study was to estimate the prevalence of Staphylococcus sciuri during bloodstream
infection and to assess the importance of the hospital environment as a possible secondary reservoir of multiresistant
bacteria capable of colonizing or infecting patients.
Patients and methods: Between June and December 2008, clinical information and samples were collected
from patients suspected to have nosocomial bloodstream infections at a tertiary hospital in Benin. The isolates
were identified, tested for antimicrobial susceptibility. Particularly attention was paid to Staphylococcus sciuri and
factors associated with the carriage. Concurrently, swabbing of environment was achieved. MALDI TOF of abundant
proteins was applied to identify and to discriminate Staphylococcus sciuri isolates.
Results: Nosocomial bactereamia incidence rate was 2, 58 cases per 1000 patient-days. The proportion of
Staphylococcus sciuri among coagulase negative staphylococci was 24.5% and represented 15% of the environment
specimens. Catheter was the commonest source of nosocomial bacteremia (41%). The frequency of resistance to methicillin for Staphylococcus aureus isolates was 36% and 44% for Staphylococcus sciuri isolates. Mass spectra
were specific for five groups of S. sciuri isolates.
Conclusion: Our survey revealed a high level of Staphylococcus sciuri among Coagulase Negative
Staphylococcus isolated from blood specimen. There is a need to institute strict hospital infection control policy and a regular surveillance of resistance to antimicrobial agents. |
