Veterinary Antibiotic Resistance and Sensitivity Information

The appropriate use of antimicrobials by veterinarians can help mitigate the further development and spread of resistance in both human and animal pathogens. Microbial resistance is a problem that affects us all. Inappropriate antimicrobial use may cause medications commonly used to ensure the health of animals and people, to lose effectiveness. Proper use of these drugs helps maintain an effective arsenal in the battle against disease. 

The AVMA has put forth a list of judicious use guidelines. These guidelines encourage the use of culture and sensitivity information to assist in determining appropriate antimicrobial therapy.  When cultures and sensitivities are not possible, the veterinarian should use all information available to select appropriate antimicrobials.  "Broad" spectrum and newer generation drugs should only be used when necessary. 

The Louisiana Animal Disease Diagnostic Laboratory (LADDL) at the Louisiana State University (LSU) School of Veterinary Medicine and the Infectious Disease Epidemiology Section at the Office of Public Health have prepared several antimicrobial profiles based on laboratory data from culture and sensitivity submissions to the laboratory.  These data may be useful to veterinarians in the empirical selection of antimicrobials. However, veterinarians should be cautious in interpreting the data.  The sampling does not reflect resistance patterns and site/organism profiles from the state as a whole, but only for the samples submitted to the LADDL.
