Decreased Clinical Severity of Strangles in Weanlings Associated with Restricted Seroconversion to Optimized <i>Streptococcus equi</i> ssp <i>equi</i> Assays

Abstract

Absence of clinical signs alone in naïve horses may be an insufficient criterion to release horses from strangles quarantine measures. Restricted seroconversion to antigen C may have been associated with decreased clinical severity. The role of a minor gene deletion in SEQ_0402 in the virulence of S. equi warrants further investigation.
