[The therapy of urinary tract infections in sows].

Fifteen sows spontaneously infected with Eubacterium suis were treated with enrofloxacin and, if necessary, with ampicillin. Before and after treatment different blood and urine parameters were determined with regard to renal function and the condition of the urinary bladder was examined by cystoscopy. Besides results of a controlled treatment in a breeding herd with a high frequency of urinary tract infections are referred. Duration of treatment with appropriate dosage should be at least 10 days. Even when a haemorrhagic inflammation was present therapy of infections with Eubacterium suis showed no problems, if the alterations were restricted to the bladder. In sows with renal insufficiency in case of ascending infection treatment is also possible on principle, but intensive infusion therapy is necessary in addition to antibiosis. Reliable estimation of the renal function can be obtained by measurement of creatinine and urea blood levels. Enrofloxacin treatment of urinary tract infections was successful in a breeding herd. An insufficient water supply and a high incidence of crystalluria were important predisposing factors.
