Streptococcus equi equi is a gram-positive bacteria that induces infection and contagious disease in the upper respiratory tract of horses, donkeys and mules. Symptoms of clinical disease, termed strangles, include bacterial colonization of the patient’s tonsils and pharynx resulting in abscessation of the lymph nodes under and behind the jaw. It is essential to isolate any horse with signs of strangles to prevent population outbreaks. The incubation period of strangles is up to 2 weeks and symptoms will be evident within 1-2 days of the onset fever. Current diagnostic testing includes detection of shedding via bacterial culture and more sensitively with molecular PCR confirmation.1 The Fluxergy S equi equi assay detects a conserved region of the S equi equi genome that is highly unique to the specific streptococcus subtype. Use the Fluxergy system to diagnose strangles with speed and sensitivity and enhance biosecurity within your clinic.
