Expertise / Research Area

Dr. Mark R. Ackermann is professor in the Department of Veterinary Pathology in the College of Veterinary Medicine with research, clinical service in surgical and post-mortem pathology, and teaching responsibilities. 

Dr. Ackermann’s laboratory investigates respiratory syncytial virus (RSV) infection in newborn lambs as a model for RSV infection in infants.   His team has determined the effects of preterm birth and other in utero stresses (e.g., alcohol/nicotine) on RSV disease severity and also identified key innate and adaptive immune responses that underlie susceptibility to RSV infection in the preterm and term lung.  They have used this model to test therapeutic interventions such as the enhancement of the dual functioning oxidase/lactoperoxidase innate defense system, administration of vascular endothelial growth factor (VEGF), and the effects of other small molecule therapeutics.  In addition, the team has determined the lambs, like infants, developed enhanced RSV disease following vaccination with formalin-inactivated RSV vaccine.  Major funding has included the NIH/NIAID, USDA/CSREES, Salsbury Endowment, Carver Foundation, and private sources.  Dr. Ackermann's previous work involved molecular and innate immunity, including work on Mannheimia haemolytica, an important pathogen in shipping fever of cattle and sheep, along with his work on bovine leukocyte adhesion deficiency (BLAD) in Holstein cattle.

Dr. Ackermann also is engaged in clinical service (diagnostic pathology) and has diagnostic expertise in respiratory diseases and gastrointestinal disease.  He has served as Interim Associate Dean of Research and Acting Chair of Veterinary Clinical Sciences as well as the J.G. Salsbury Endowed Chair and served on NIH study sections and USDA review panels.
