Antibiotic Sensitivities of Oral Mycoplasma

¹ Multidiscipline Laboratory, Schools of Medicine and Dentistry, Georgetown University, Washington, DC 98105, USA

Antibiotic sensitivities of five human species and one saprophytic species of mycoplasma were determined by the disk method. All were resistant to the antibiotics that act on cell walls. All were sensitive to the tetracyclines, chloramphenicol, kanamycin, and neomycin. Only Mycoplasma pneumoniae and Mycoplasma laidlawii B were sensitive to erythromycin, oleandomycin, streptomycin, and dihydrostreptomycin.
