Abbreviated taxonomy: Bacteria; Firmicutes; Lactobacillales; Streptococcaceae; Streptoccus; Streptococcus equi. Lymphadenopathy, especially of mandibular, parotid, and retropharyngeal lymph nodes; may abscess and impinge on the airways (thus the familiar name, which is derived from the verb strangle); causes mucopurulent nasal discharge, anemia, cough, can progress to lower airway infection, and may recrudesce months later as mesenteric lymphadenopathy with abscessation (so-called bastard strangles) and lead to signs of colic. A vaccine is available.
