  1. Tick Submission in MI Local Health Department, Environmental Health Division maintains tick kits Each tick kit contains: • Tick submission form • Instructions • Mailing container Specimens can be returned to LHD or mailed to Michigan department of Agriculture.

  2. Ear-punch biopsy

  4. Recovery

  5. Deer Surveillance • Hunter-killed deer • Fall 1988-1990 • Over 4,000 deer checked • Dermacentor albopictus found commonly • No Ixodes scapularis found

  6. Canine Serosurvey • 1992 & 1993 • 6 private practices

  7. Canine Serosurvey Methods • Random Samples • Healthy dogs • Serum from heartworm test • Blinded study • 2 step lab protocal • Screening IFA/ELISA; W.Blot

  10. Seroprevalence Conclusions • Good study design • Extremely low level of seropositive dogs in Michigan • Results correlate with other ecologic & epidemiologic data • Menominee county

  13. Endemic Area

  14. Menominee CountyFactors contributing to Lyme Disease • UP banana belt; warmer temperatures • Rural ecology; emphasis on outdoor life and hunting • Landscape of forest, abandoned dairy farms, active dairy farms, waterways; mixture of southern deciduous and northern boreal forest • Northern limit of white-footed mouse distribution • Extremely high deer density

  17. Where might Lyme Disease emerge next? • South West Michigan • A population of Ixodes Scapularis was recently found in NE Indiana, bordering Michigan.* • Coastal Counties of Michigan • Bird migration has been a source of tick dispersal. **

  19. Test Region GIS Risk Model • Project objectives: • (1) Develop SW Michigan • as test site for quantitative • Lyme disease ecological • risk assessment • (2) Enroll vet clinics in SW • Michigan as sentinels for • ticks and canine sera • (3) Trap rodents at new sites, • Inspect for ticks, isolate • B. burgdorferi • Check locally shot deer • for ticks Dept Microbiology & Molecular Genetics Mich State Univ

  20. Is lower Michigan under invasion by I. scapularis ticks, and “Lyme disease?” If so, does this provide an opportunity to test and improve the risk map based upon tick habitat suitability?

  21. Tick 4/300 B. burgdorferi positive rodents Tick 2/1,000 seropositive dogs
