Chlortetracycline (trade name Aureomycin, Lederle) is a tetracycline antibiotic, the first tetracycline to be identified. It was discovered in 1945 by Benjamin Minge Duggar working at Lederle Laboratories under the supervision of Yellapragada Subbarow. Duggar identified the antibiotic as the product of an actinomycete he cultured from a soil sample collected from Sanborn Field at the University of Missouri. The organism was named Streptomyces aureofaciens and the isolated drug, Aureomycin, because of their golden color. Chlortetracycline inhibits cell growth by inhibiting translation. It binds to the 16S part of the 30S ribosomal subunit and prevents the amino-acyl tRNA from binding to the A site of the ribosome. In veterinary medicine, chlortetracycline is commonly used to treat conjunctivitis in cats.

Route of Administration: Oral

In Vitro Use Guide

Chlortetracycline activity was determined against 37 Mycoplasma putrefaciens isolates. Chlortetracycline was tested at concentrations ranged from 4 to 0.03 mg/ml/ The MIC was defined as the lowest concentration in which there was no bacterial growth, as evidenced by a lack of pH color change at the time the drug-free growth control showed a color change. This change of color was evident after 24 h of incubation.
