Chlortetracycline

Chlortetracycline (trade name Aureomycin®, Lederle) is a tetracycline antibiotic, and was the first tetracycline to be discovered. It was discovered in 1945 by Dr Benjamin Duggar in a soil sample from Sanborn Field at the University of Missouri, yielding an actinomycete, Streptomyces aureofaciens (hence the name Aureomycin). In veterinary medicine, it is commonly used to treat conjunctivitis in cats.
