An epidemiology investigation continues at Ellis Park in Henderson County after a horse there was confirmed as having 'strangles', a bacteriological infection found in horses. Symptoms of strangles include fever, breathing difficulties and swelling of the lymph nodes....Read Press Release.......
Monday, July 25:
Nasal pharyngeal wash samples collected on July 7 and again on July 12, 2005 from horses stabled in Barn 9 at Ellis Park (16 thoroughbreds and a pony) were tested for the detection of S. equi bacterium by both culture and PCR testing. Results of this diagnostic testing were reported as negative to both the culture and PCR. A third sample collected from the guttural pouches of these horses on July 18 were also tested with the results again being reported as negative on both the culture and PCR. In addition to the diagnostic testing completed, an endoscopic examination of the guttural pouches was performed with no abnormal findings.
With these results and examination, this group of horses has successfully completed the protocol established to detect Streptococcus equi in horses. Based on these negative results and findings the quarantine and all restrictions were rescinded.
Monday, July 18:
Endoscopic examinations were completed on each of the horses stabled in Barn 9. There were no abnormal findings of the guttural pouches observed. Lavage samples were collected from each of the pouches with these samples submitted for culture and PCR testing.
Friday, July 15:
Results from the second round of samples collected on July 12 were reported negative by both culture and PCR for S. equi. There have been no additional fevers or other symptoms of disease observed in this stable since the index case.
The third, and more extensive round of tests are scheduled to be completed next week. An endoscopic examination of the guttural pouches will be made with lavage samples collected from each pouch will be completed.
Tuesday, July 12:
Results from the initial round of samples collected from the horses in Barn 9 have been received with all animals reported negative. Nasal Wash samples from the 17 horses (16 TB in training and 1 Pony) stabled in Barn 9 were reported as negative on both culture and PCR for S. equi.
A second round of samples were collected from each of the 17 animals.
A third series of test, to include an examination of the guttural pouches will be scheduled following results from the second round being received.
Thursday, July 7:
17 Animals stabled in the affected barn were quarantined with samples collected and submitted for testing. Animals stabled in the barn are permitted entry onto the track only during designated times following regular training hours.
Tuesday, July 5:
Culture results confirmed the diagnosis of S. equi as affecting the filly.
Monday, July 4:
The filly was moved from the track to a private quarantine facility.
Friday, July 1:
Lymph node involvement was suspected and the filly was isolated from the general population. A sample, collected from the enlarged lymph node, was submitted for culture. Movement into and out of the affected barn was halted, with additional bio-security measures implemented.
