According to a second round of tests on quarantined horses, the number of confirmed cases of strangles has declined and there is no evidence that the disease has spread at Churchill Downs’ Trackside Louisville training center in Louisville, Ky.  

The Kentucky Department of Agriculture reported on March 23 that the tests performed on 49 horses–including 43 quarantined in the west end of barns K and L at Trackside–show that 40 tested “negative” for strangles.

The results of the second round of tests found that:

• 28 horses returned negative results in both of their strangles tests; 
  
• Six horses tested positive for the disease on both occasions; 
  
• 12 horses that had positive results for infection on their first test returned a negative result on the second tests.

Test results on three horses were still pending
