[Studies of the etiology of cystopyelitis in hybrid swine].
Studies were carried out on the etiology, clinical picture, morphologic changes, and methods of prophylaxis of the cystopyelitis in hybrid pigs. It was established that in the cases studied the etiologic part is most probably played by Escherichia coli having pronounced virulence for albino mice. Clinically the disease was manifested with hematuria--the cardinal diagnostic symptom; histologically there were nephritis, pyelonephritis, and strong edemas on the wall of the bladder. When hematuria appeared the affected pigs died (at the rate of 100 per cent) as a result of acute anemia. Prophylactic measures have been especially successful with the use of streptomycin to which the isolated coli strains proved sensitive.
