Calvin Keeler- ckeeler@udel.edu,  Department of Animal and Food Sciences, University of Delaware

Dr. Keeler is a Professor of Molecular Biology in the Department of Animal and Food Sciences and Director of the Avian Biosciences Center at the University of Delaware. In the area of avian viral pathogenomics his research efforts are directed towards understanding the molecular ecology of infectious laryngotracheitis virus (ILTV) with the goal of identifying novel live attenuated vaccine strains of the virus. Another research focus is the avian innate immune response, with emphasis being given to characterizing differences in the regulation of the inflammatory response between ducks and chickens using avian influenza virus as a model.  Of particular interest is the characterization of the avian respiratory microbiome (bacterial, viral, and fungal) in order to better understand the microbial interactions responsible for avian respiratory disease complex (RDC).

 

Sunil Khattar- skhattar@umd.edu,  Department of Veterinary Medicine, University of Maryland

Dr. Khattar in the department of Veterinary Medicine at the University of Maryland has been working on development of Newcastle disease virus (avian paramyxovirus serotype 1) and other avian paramyxovirus serotypes 2-9 as a vaccine vector to control infectious bronchitis virus (IBV) infection in chickens. Delmarva region has a large number of commercial poultry farms and private backyard poultry producers. The large poultry population is under threat from IBV.

IBV is the primary cause of morbidity and mortality in the poultry. There are multiple variants

(antigenic and genotypic types) of IBV such as Arkansas (Ark), Connecticut (Conn), Delaware (Del), Georgia 98 (GA98), Georgia 08 (GA08) and Georgia 13 (Ga13) in the USA. These variants do not cross protect and new types of the virus continue to arise due to mutation and recombination in the viral genome. Inactivated and live attenuated vaccines have been frequently used in poultry to control IB. However, these vaccines cannot completely control the outbreaks. 

Another major limitation of these vaccines is that the vaccinated birds cannot be differentiated serologically from naturally infected birds. To overcome these limitations, we are developing recombinant Newcastle disease virus and other recombinant avian paramyxoviruses expressing immunogenic S protein of IBV to control IB.

LLC (ATP) and both companies have been collaborating with University of Maryland Eastern Shore in a variety of interrelated activities, supported by MIPS and other funding sources, which will benefit the poultry industry and enhance the environment of the Chesapeake Bay watershed.

CRBBP Process: ATP’s patent-pending Combined Remediation Biomass and Bio-Product Production (CRBBP) Process to use sorghum to first, extract excess phosphorus from

Chesapeake Bay watershed farm soils, and then to convert the resulting biomass into innovative and cost-advantaged bio-products, like fillers which enhance the performance of composites and plastics or use as poultry house bedding. NRCS EQIP Grant: In support of its collaboration with UMES, ATP-MD has been awarded an EQIP Grant to demonstrate its planting of biomass sorghum as a Best Management Practice (BMP) cover crop. Upon gaining BMP status, producers, which deploy this practice, will be awarded conservation payments, which substantially reduce the costs to establish this crop.
