Veterinary Director, Virology Virology

This laboratory is an official state agency delegated the task of implementing the NPIP in GA. As such I am involved in monitoring of avian influenza (AI) and exotic Newcastle disease virus RNA from clinical samples by real-time RT-PCR. In the past five years I have developed PCR-based diagnostic assays for the detection of infectious bronchitis virus genotypes, laryngotracheitis, infectious bursal disease, reovirus, chicken anemia virus, and Chlamydia-specific virual RNA/DNA from the clinical specimens. Additionally, we successfully adopted automated cycle sequencing method for genotyping IBD and IBDV field isolates described originally by Dr. Gelb(University of Delaware).

Bacteriology Laboratory Technical Liaison and Technical Logistics Support Bacteriology

The purpose of the bacteriology department is to isolate and identify bacteria from poultry or poultry environmental samples. The vast majority of the samples that are submitted to the department are environmental samples for quantitative counts or for Salmonella testing.

As an NPIP authorized laboratory we are involved in testing environments of poultry houses for Salmonella. This involves isolation, confirmation, and serotyping isolates. Another part of our NPIP activities is testing samples for the presence of MG and MS using PCR.
