Antibiograms of gram-negative bacteria recovered from clinical specimens at the University Hospital of the West Indies (August, 1982 - January, 1983)

ABSTRACT

The sensitivity patterns of gram-negative organism were recorded over a six-month period from August 1982 to January 1983, and percentage sensitivities were calculated for urine and non-urine isolates. Sensitivity patterns did not differ substancially from those previously reported. However, urine isolates were shown to be significantly more resistant to antimicobials when compared with non-urine isolates. Multiresistant strains of Serratia marcesens demonstrated considerable resistance to all anibiotics except amikacin. Analysis of data on a monthly basis revealed significant changes in the antibiograms of E. coli and Acinetobacter sp. Antimicrobials on restricted usage maintained a high level of activity with the exception of tobramycin. (AU)
