Disease Risk Assessment No. 16-62-0509-92.

2.  AUTHORITY.  The scheduling of this assessment was based on AEHA Form 
250, Request for USAEHA Field Services, 15 October 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 Rucker, Alabama.

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 Laboratory at Fort 
George G. 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 [sic] none of the ticks tested positive for 
the Lyme spirochete and none of the deer were serologically positive for 
exposure to Lyme disease, Lyme and other tick-borne diseases are known to 
exist in the state of Alabama.  Installation personnel should continue to 
practice personal protective measures to reduce the possible disease threat.

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.
