Susceptibility of gram-positive bacteria isolated from a paediatric hospital environment to antibiotics

Susceptibility of Gram-positive bacteria isolated from the hospital environment to antibiotics was determined. About 19% strains were resistant to most tested antibiotics. Among 30 coagulase-negative staphylococci, 8 of them have been found to be resistant to 6-13 antibiotics, whereas among 15 strains of S. aureus only one was resistant to 6 antibiotics. Only gentamicin was effective to all tested Gram-positive strains, whereas ceftazidim, tetracycline and doxycycline were ineffective to the most tested bacteria.
