Oxytetracycline hydrochloride is a broad-spectrum antibiotic. Its spectrum, antibacterial principle and application are basically the same as tetracycline. Many Rickettsia, Mycoplasma, Chlamydia, Treponema, Amoeba and certain Plasmodium are also sensitive to this product. Enterococci are resistant to this. Others such as Actinomycetes, Bacillus anthracis, Listeria monocytogenes, Clostridium, Nocardia, Vibrio, Brucella, Campylobacter, and Yersinia are sensitive to this product. The product has a certain activity against Neisseria gonorrhoeae and meningococcus, but it is resistant to penicillin. Neisseria gonorrhoeae is also resistant to oxytetracycline.
