Strangles, Equine - contd.

Diagnosis
Strangles is usually diagnosed by means of its clinical signs, which include a fever of 106 F, or 41 C, and lymph nodes that are swollen or abscessed, and oozing serum, pus, and fluid. Identifying Streptococcus equi bacteria in the discharge or pus coming from ruptured or surgically lanced lymph nodes, or in discharge from the nostrils, provides a definitive diagnosis of strangles.
