Prevalence of strains of Staphylococcus epidermidis and other coagulase-negative staphylococci with biofilm-forming ability at a department of hemato-oncology
OBJECTIVES: Staphylococcus epidermidis and coagulase-negative staphylococci generally are important causative agents of hospital-acquired infections. A significant role in this process is played by their common ability to form biofilm, a highly organized community of microorganisms adhering to inert surfaces. The study aimed to determine the prevalence of these bacterial strains and their ability to form biofilm at the Department of Hemato-Oncology, University Hospital Olomouc.
MATERIAL AND METHODS: Over a period of 12 months, samples of air and swabs from surfaces and staff members were collected. The samples were subjected to standard microbiology tests; coagulase-negative staphylococci were identified. Staphylococcus epidermidis strains were confirmed by polymerase chain reaction and subsequently tested for biofilm formation.
RESULTS AND CONCLUSIONS: Coagulase-negative staphylococci were found in 81 samples, most commonly swabs from staff members. S. epidermidis accounted for 60 % of all positive results; it was most frequently isolated from surface swabs. Almost half of S. epidermidis strains were able to form biofilm. These strains were found in the environment characterized by cleanliness classes FED-STD-209E (USA) - 10 000 and FED-STD-209E (USA) - 100 000. Thus, they pose a risk for immunocompromised patients staying there. Since coagulase-negative staphylococci were also found in healthcare staff of the department, the staff members may play a key role in the transmission of these microorganisms to patients.
