Differences in isolation rate and antimicrobial susceptibility of bacteria isolated from foals with sepsis at admission and after ?48 hours of hospitalization.


ABSTRACT:

Background

Antimicrobial treatment protocols for foals with sepsis that do not improve clinically often are adjusted based on bacteriological and antimicrobial susceptibility testing results from samples collected at hospital admission.

Objectives

To evaluate whether hospitalization for ?48?hours affects bacteriological and antimicrobial susceptibility testing results.

Animals

Two-hundred sixty-seven foals <30?days of age admitted to a neonatal intensive care unit and diagnosed with sepsis.

Methods

Medical records were reviewed retrospectively to identify foals with sepsis and positive bacteriological cultures. Results from samples collected at hospital admission were compared to those collected ?48?hours after admission. Logistic regression for clustered data and exact logistic regression were used for statistical analysis.

Results

Three-hundred fifty-three unique bacterial isolates were obtained from 231 foals at hospital admission and 92 unique bacterial isolates were obtained from 57 foals after ?48?hours of hospitalization. Relative isolation frequency after ?48?hours of hospitalization increased for Acinetobacter spp., 0.6% versus 3.3% (odds ratio [OR], 7.63; 95% confidence interval [CI], 1.28-45.45); Enterococcus spp., 4.8% versus 19.6% (OR, 5.37; 95% CI, 2.64-10.90); Klebsiella spp., 5.1% versus 10.9% (OR, 2.27; 95% CI, 1.05-4.89); Pseudomonas spp., 3.0% versus 7.6% (OR, 3.49; 95% CI, 3.49-240.50); and Serratia spp., 3.0% versus 5.4% (OR, 20.23; 95% CI, 2.20-186.14). Bacteria isolated after ?48?hours of hospitalization were less susceptible to all tested antimicrobial drugs, except for imipenem.

Conclusions and clinical importance

Decreased antimicrobial susceptibility of bacteria isolated after ?48?hours of hospitalization provides a rationale for repeated bacteriological culture and susceptibility testing in hospitalized foals with sepsis.
