MORALES, A et al. Aminoglycosides and quinolones resistance in a equine with oesophagitis report of case. AVFT [online]. 2014, vol.33, n.3, pp.84-87. ISSN 0798-0264.

The objective was report of case of resistence a aminoglycosides and quinolones resistance in a isolation of Escherichia coli in a equine with suppurative oesophagitis. Refer a horse (Equus caballus) with esophageal obstruction history, esophagostomy and suppurative esophagitis not responsive to combination therapy with penicillin, gentamicin or ceftiofur with dates from 21 days of treatment. Were practice necropsy and sampling for bacteriological and histopathological study. The necropsy showed severe esophagitis suppurative, coagulation necrosis, abundant cellular debris, with infection of muscle tissue, periflebitis and periarteritis. Pericarditis and exudative epicarditis focal purulent. Histological sections revealed esophagitis abscess with periarteritis, arteritis, perineuritis, neuritis with coagulation of necrosis and necrosis liquefact, fibroplasic response and granulation tissue in the neck and right jugular furrow. Were observed content abundant types of bacteria spherical, Gram negative, positive staining especially Warthing Starry. The bacteria isolated showed the presence of E. coli. antibiogram revealed whose resistance to gentamicin, ciprofloxacin and nalidixic acid. In conclusion we report a resistance to aminoglycosides in an esophageal infection in a horse racetrack, National Institute of “La Rinconada Caracas Venezuela.
