Bacterial Colonization and Antimicrobial Susceptibility Patterns of Wound Isolates in a Hospital in Abeokuta, Nigeria.

Abstract

A retrospective study on the rate of isolation and antibiotic sensitivity profile of microbial isolates from wound infections at the Federal Medical Center Abeokuta was conducted from April 2009 to March 2010. A total of 209 wound swabs were retrospectively studied, for colonial characteristics, gram reaction and antibiotic susceptibility. An isolation rate of 177(84.7%) was recorded with gender distribution of males 105(50.2%) and females 104(49.8%). The age group 16 to 30 years gave 71(34.0%) while above 60 years had 21(10%). The bacteria isolation pattern was Pseudomonas aeruginosa 45(25.4%), E. coli 42(23.8%), Klebsiella spp. 36(20.3%), Proteus spp. 28(15.8%) and Staphylococcus aureus 26(14.7%). Gentamycin was the most susceptible with a frequency of 40% followed by Ofloxacin. The high diversity of organisms and poor susceptibility pattern signifies the need for proper infection control and laboratory investigation of all patients presenting with wound infections.
