Salmonella is one of the leading causes of chronic diarrhea in adult horses. Treatment in these cases is complicated and the prognosis is reserved. Following work communicates a clinical case of salmonellosis in an equine castrated male, raza polo Argentino, 5 years old. In July 2015 the horse up to a ganadero establishment of Tandil party with poor body condition, diarrhea and weakness. 24/8 consult your veterinarian and the horse was in a pen with hens, deposed, with four members, pale mucous edema. He is a treatment with febendazole (10 mg/kg/24 h for 5 days). 13/9 moved to a guesthouse in the city of Tandil for a better follow-up and presents hyperthermia (40 ° C), pale mucous membranes, profuse watery diarrhea. It is 1 mL/10-20 kg of weight per day of Sulphadimidine 20 g, trimethoprim 4 g Loperamida HCl 0, 04 g, for 3 days. Modifies the diet pellets, alfalfa and oats. Blood is drawn 15/9 and fecal matter to review growth, which was negative. 30/9 is again low with edema in foreskin and ventral abdomen, presents hyperthermia (40.2 ° C), pale mucous membranes, decay and lossof appetite. He is blood count (table 1) and extracted fecal matter to review growth, which was negative and microbiological examination.An 1/10 is a hydration therapy and blood is transfused. Administered penicillin 30000 IU/Kg every 24 h, gentamicin 6.6 mg/kg/IV every 12 h and dose for 5 days endotoxicas flunixin meglumine. The stool was subjected to the systematic process for the isolation and identification of microorganisms: colorations, culture on blood agar and Mc Conkey, pre-enrichment broth selenite and peals in Salmonella-Shigella agar, in aerofilia at 37 ° C. Peal of 48 h develops lactose colonies negative with a gram negative Bacillus sulfhydryl is that TSI, LIA, catalase, oxidase and reduction of nitrates, IMViC, urea and mobility. These tests helped identify a Salmonella sp 5/9. The isolate was sensitive as: enrofloxacin, gentamicin, Ac. nalidixic, trimethoprim - Sulfadiazine and ceftriaxone. Isolation, signs, and blood chemistry consistent with a case of chronic salmonellosis. The transmission could be due to carriers other living animals. The determination of the species will allow to further genetic studies. 9/9-equine worsens, remains in decubitus and its euthanasia is performed.
