title: Treatment of Mycoplasma hyorrhinis contaminated tissue cultures with a mixture of antibiotics.
abstract: Results obtained using a combination of antibiotics to control mycoplasmas in tissue cultures are described. Cell strains and established cell lines from several mammalian species grown in tissue culture were found to be highly contaminated with M. hyorrhinis. Cultures were treated with a mixture of three antibiotics consisting of gentamicin, tetracycline and chloramphenicol, and since that time tests for mycoplasmas in the treated cultures have consistenly yielded negative results. Apart from a transient cytostatic effect on the cells during the treatment, no apparent unwanted effects were observed. The mixture of three antibiotics appeared to be superior to treatment with antibiotics singly or combinations of two antibiotics.
