Sensibilita in vitro di microrganismi patogeni nei confronti di antimicrobici di diffuso impiego veterinario

摘要

An in vitro investigation on sensitivity of some pathogens isolated from bovine, equine and swine species to chemotherapeutic agents diffusely used in veterinary medicine was carried out. In particular, it was evaluated the activity of benzylpenicillin, ampicillin, cefalexin, cefoperazone, ceftiofur, oxytetracycline, chlortetracycline, doxicycline, aminosidine, kanamycin, tiamphenicol, nalidixic acid, flumequine and enrofioxacin. Ceftiofur and enrofloxacin showed a greater antimicrobial efficacy; on the contrary, tetracyclines showed a smaller activity, whereas drugs diffusely used as aminoglycosides, tiamphenicol e #beta#-lactams resulted poorly active.
