Multiorgan Disease and Death Associated With Streptococcus equi spp. zooepidemicus in a 2-Month-Old Foal

A 2-month-old Andalusian colt in central Spain presented dyspnea, diarrhea, and depression. Despite the initial treatment for presumptive pneumonia caused by Rhodococcus equi, after 1 hour, the colt showed signs of shock and died. The necropsy revealed multiple abscesses in the lung, as well as enlarged mesenteric lymph nodes, and hemorrhagic peritonitis. Samples were taken from trachea, lung parenchyma, small intestine, and colon. All samples yielded a pure culture of Streptococcus equi spp. zooepidemicus, whereas R.  equi was excluded by using a specific qPCR performed on all samples.
