Commonly used antibiotics include doxycycline, tetracycline, chloramphenicol, ciprofloxacin, ofloxacin, and hydroxychloroquine. These include clindamycin, anisomycin, cycloheximide, chloramphenicol, tetracycline, streptomycin, erythromycin, and puromycin. The antibiotics often used are streptomycin, chloramphenicol and tetracycline. Most people respond to oral therapy doxycycline, tetracycline hydrochloride, or chloramphenicol palmitate. Other frequent resistance targets include aminoglycosides, fluoroquinolones, tetracyclines, chloramphenicol, and trimethoprim/sulfamethoxazole. These genes provide resistance to aminoglycosides, aminocyclitols, tetracycline, and chloramphenicol. For treatment of infected cats, antibiotics are the preferred treatment, including tetracycline, chloramphenicol or streptomycin. Streptomycin, gentamicin, tetracyclines and chloramphenicol are all able to kill the causative bacterium. Other antibiotics proven to be effective include cotrimoxazole, erythromycin, tetracycline, chloramphenicol, and furazolidone. For example, chloramphenicol and tetracyclines are antagonists to penicillins and U.S.s. Chinchillas may be treated with chloramphenicol, neomycin, or spectinomycin for digestive problems. Other antibiotics, such as chloramphenicol or amoxicillin may also be used. Other antibiotic choices include enrofloxacin and chloramphenicol. Treatment options may include nitrofurantoin, fosfomycin, mecillinam and chloramphenicol. Strains that are resistant to doxycycline and chloramphenicol have been reported in northern Thailand.
