High cardiac troponin I plasma concentration in a calf with myocarditis.

Abstract

A 15-day-old Brown Swiss calf, whose dam had suffered from foot-and-mouth disease, was presented with a history of depression and failure to suckle. The calf had an irregular cardiac rhythm and increased plasma cardiac troponin I (cTnI) detected with a commercial human immunoassay. The calf died the following day and myocarditis was detected. The cTnI assay may be useful in diagnosis of myocarditis in cattle.
