Exudative Pharyngitis Following Experimental Mycoplasma hominis Type 1 Infection

Abstract
It has been known for a number of years that organisms of the genus Mycoplasma can produce severe and often debilitating respiratorytract disease in birds, mice, rats, goats, sheep, and cattle.1-3 However, it was not until recently that a Mycoplasma organism was implicated in respiratory-tract disease of man.4 Recently, the Eaton agent, originally recovered in eggs in 1944, was successfully cultivated in a cell-free artificial agar medium.5-7 The organism propagated on agar medium was shown to be a Mycoplasma and was designated Mycoplasma pneumoniae.8 Previous studies had shown that this organism was the etiologic agent of cold agglutinin-positive atypical pneumonia.9,10 In addition, the agent had been associated with other milder forms of respiratorytract disease.11 In part, the role of M pneumoniae in human respiratory disease was established during a series of studies with volunteers.12,13 After the identification of the Eaton agent as a
