Bacteriological and serological studies after ileovesical diversion in dogs.

The risk of urinary tract infection after ileovesical diversion was studied by means of bacteriological and serological analyses in 8 mongrel dogs. Cultures of bladder contents showed heavy growth of the same bacterial strains as were found in the distal ileum. Cultures of the pelvic urine contained lower amounts of the same strains of bacteria. The levels of serum antibody titres to Escherichia coli and Proteus mirabilis were elevated only in 3 out of 100 sera examined. These slightly increased titres were not related to any obvious infection in the urinary tract. High C-reactive protein concentrations were noted in 3 dogs in connection with diagnosed inflammatory conditions. Colonization of the urinary tract after oral administration of selected test-strains could not be shown.
