[Comparative evaluation of the sensitivity to Mycoplasma pneumoniae of organ cultures of the trachea and lungs of certain animals].

A possibility was shown of cultivation of M. pneumoniae in the organ cultures of the trachea and the lungs of a pig embryo. 5-7-day guinea pigs, and 3-5-day chicks. The lung and tracheal explants of chicks possessed the greatest sensitivity to M. pneumoniae. M. pneumoniae strains were isolated from the nasopharyngeal smears and washings from the bronchi obtained in bronchoscopy of patients suffering from chronic pneumonia, with the use of organ culture of chick trachea. Explains of chick trachea could serve as a medium for the isolation of M. pneumoniae from the patients.
