Strangles is a highly contagious disease caused by bacteria known as Streptococcus equi. Although horses of any age can be affected, strangles typically targets weanlings and yearlings.

TRANSMISSION: bacterial exposure via direct contact with infected horses or indirect contact with contaminated objects (stalls, tack, trailers, hands)

CLINICAL SIGNS: fever, depression, nasal discharge, cough, swollen lymph nodes, reluctance to swallow

PROGNOSIS: recovery can take weeks to months. Some horses become chronic shedders of bacteria.

PREVENTION: initial vaccination series with PINNACLE® I.N. followed by annual revaccination
