[Pathogen spectrum and pathways of infection at an intensive care burn unit].
Coagulase-negative staphylococci have gained increasing importance in burns, whereas interest is no longer focussed on Pseudomonas bacteria. By means of microbiological analysis of swabs taken from patients, environment and staff, we trailed the routes of infection in an intensive-care unit for burns. Analysis of patients: In 27 out of 11 patients the same biotype of Staphylococcus epidermidis could be identified; 22 of these occurred in swabs from wounds. The phagotypification of Staphylococcus aureus showed the same phagotype in 28 out of 41 swabs taken from infected wounds of 10 patients. The pathogen mostly caused the destruction of already healed grafts in a later phase of the treatment. Further microbiological analysis showed a severe infestation of the patients by enterococci. Analysis of environment: Here, greatly increased counts of coagulase-negative staphylococci of the same lysotype as in the patients could be demonstrated. Analysis of staff: The naso-pharyngeal area is of minor importance in the spreading of germs, whereas that of protective clothing and especially the hands should be considered to be more crucial. Regular environmental tests enable rapid detection of hygienic errors so that appropriate countermeasures can be taken.
