Disease Risk Assessment No. 16-62-0558-92.

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 
Redstone Arsenal, Alabama.  

4.  GENERAL.  Parasitic ticks and blood samples were obtained from 
hunter-killed white-tailed deer.  No ticks were found on any of the deer 
examined.  Whole blood was processed to obtain serum which was then sent to 
the Regional Veterinary Laboratory at Fort George G. Meade, Maryland for 
analysis.  The results of these tests have been recieved.

5.  FINDINGS AND DISCUSSION.  One of the 32 serological tests was positive 
for the spirochete, Borrelia burgdorferi, which is the causal organism for 
Lyme disease (see Appendix E, serological results).

6.  CONCLUSION.  Since one of the deer was serological positive for 
exposure to Lyme disease, installation personnel should continue to 
practice protective measures.

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