ABSTRACT: The aim of this
study was to review the changes in distribution of bacterial populations and
their antibiotic sensitivity over 12 years in a tertiary care burn unit.
Understanding the periodic variation of isolated microorganisms and their
antibiotic sensitivity helps in selecting the appropriate antimicrobial therapy
before culture and sensitivity are reported. It also aids the design of antibiotics
protocols. The study was retrospective. The data were obtained from the
computerised hospital medical record system and the burn unit records. Overall, Pseudomonas aeruginosa was the most
commonly isolated microorganism followed by Staphylococcus aureus, Meticillin-resistant
Staphylococcus aureus (MRSA),
and the genus Acinetobacter. Acinetobacter isolation rose rapidly
and became more prevalent than P. aeruginosa over the last three years.
Other organisms became isolated more
frequently, such as Klebsiella pneumoniae, but their overall prevalence
was low. Pseudomonas species
frequency of isolation declined. P. aeruginosa, MRSA, and other microorganisms showed increasing
sensitivity to a number of antibiotics. MRSA remained highly sensitive to
vancomycin, and Acinetobacter showed high resistance to all antibiotics
tested except colistin. K. pneumoniae was highly resistant to most of
the antibiotics tested except the carbapenems, but the resistance to
carbapenems increased over time.
