Biography

Research Interests

The goal of Dr. Credille’s research program is to better understand the epidemiology, mechanisms, and impact of antimicrobial resistance in Mannhaemia haemolytica, the most common bacterial organism isolated from the lungs of beef cattle with bovine respiratory disease (BRD). Additionally, his research program is evaluating the differences in immune responses to viral and bacterial respiratory pathogens in beef calves at high and low risk of developing BRD. Long term, he hopes to use the information he obtains from his studies to develop antimicrobial use and vaccination strategies that improve the health and welfare of beef cattle throughout North America and improve the sustainability and profitability of beef cattle producers in Georgia.

Current projects include:

  1. Is Metaphylaxis the Primary Contributor to Multi-Drug Antimicrobial Resistance in Bovine Bacterial Respiratory Pathogens (Supported by the Georgia Commodity Commission for Beef)
  2. Disposition of Ampicillin Trihydrate in Plasma and Pulmonary Epithelial Lining Fluid of Holstein Calves Prior to and After Experimental Infection with Mannheimia haemolytica (Supported by the American Veterinary Foundation/Veterinary Pharmacology Research Foundation)
  3. Plasma and tissue disposition of ceftazidime after the administration of multiple intravenous doses to healthy neonatal foals (Supported by the University of Georgia Love of the Horse Fund)
  4. Georgia Rural Veterinary Experience:  A Program to Enhance Student Exposure and Interest in Rural Veterinary Practice (Supported by the Georgia Commodity Commission for Beef)
