Abstract
The aim of this paper was to assess the frequency of colonization of the mucous membranes of the nose and/or throat by Staphylococcus aureus in elderly people from the Care Center in Lublin. The rate of colonization of the upper respiratory tract by S. aureus was 58.62%. Nasal carriage wasfound in about 59% of the carriers. About 90% of the S. aureus isolates were insensitive to penicillin G. All the isolates were classified as methicillin-susceptibile S. aureus (MSSA) also showing sensitivity to: erythromycin, gentamicin, clindamycin, ciprofl oxacin, vancomycin, teicoplanin, fusidic acid, rifampicin, chloramphenicol and sulfamethoxazole/trimetoprim. The majority of the isolates (81%) were sensitive to tetracycline. All the isolates were sensitive to new antibiotics, such as dalfopristin/quinupristin, linezolid and tigecycline. The high drug sensitivity of S. aureus isolates from the elderly people in the Care Center indicate that in the assayed population several antibiotics and chemiotherapeutics may be useful in the treatment of infections of staphylococcal etiology.
