4 species of Mycoplasma genome are known to form super- antigen. In this patient, initial Mycoplasma IgM titer at pres- entation was positive and repeat Mycoplasma IgM titer serol- ogy was negative, favoring a true positive test at initial KD presentation. To elucidate a true relationship, if any, between Mycoplasma infection and KD, Mycoplasma testing should be considered in patients found to have KD when clinically suspected which may ultimately aﬀect severity of disease, prognosis, and treatment. The type of testing to pursue to determine acute Mycoplasma infection in the face of KD, however, remains a dilemma. Disclosure There is no source of grant or industrial ﬁnancial support.
