Disease Risk Assessment No. 16-62-0504-92, Fort Stewart, Georgia, 27-30 
December 1991.

2.  AUTHORITY.  The scheduling of this assessment was based on AEHA Form 
250, Request for USAEHA Field Services, 7 August 1991.

3.  PURPOSE.  The purpose of this initial risk assessment was to obtain 
deer serum and parasitic ticks to provide a portion of the baseline data 
needed in the preparation of a definitive Lyme Disease Risk Assessment for 
Fort Stewart.

4.  GENERAL.  Parasitic ticks and blood samples were obtained from hunter- 
killed white-tailed deer.  Ticks were processed at Fort McPherson and the 
above mentioned report was submitted.  Whole blood was processed to obtain 
serum which was then sent to the Regional Veterinary Medical Laboratory at 
Fort George Meade, Maryland for analysis.  The results of these tests have 
been received.

5.  FINDINGS AND DISCUSSION.  All of the serological tests were negative 
for the spirochete, Borrelia burgdorferi, which is the causal organism for 
Lyme disease (see Appendix G, serological results).

6.  CONCLUSION.  Although only 8 percent of the Lone Star ticks and 5 
percent of the black-legged ticks tested positive for the Lyme spirochete 
and None of the deer were serologically positive for exposure to Lyme 
disease, installation personnel should continue to practice personal 
protective measures.

7.  Questions concerning these test results should be directed to MAJ 
Michael Collyer, Chief, Entomological Sciences Division at DSN 572-2564 
or 572-2578.
