This study reports a case of parasitism by Dioctophyme renale in a supernumerary kidney and abdominal cavity of a female cat in Brazil. The three-year-old cat of indeterminate breed presented abdominal distension and was taken to the University of Contestado Veterinary Hospital in Canoinhas, state of Santa Catarina, since the owner suspected pregnancy. An ultrasound scan did not confirm pregnan...

Some properties of the pili of the gram-positive bacteria Corynebacterium renale were described. A relationship was found between the morphological features of pili and the types of C. renale. Strains of types I and III usually possessed a small number of pili, whereas those of type II possessed numerous pili. Thick and long bundles of pili characteristic of C. renale were frequently observable...

Growth of Corynebacterium renale in vitro on low-iron medium (1.34 micron) was only slightly less than that on high-iron media (7.16 and 9.85 micron). However, studies on C. renale-induced pyelonephritis using the rat as an experimental model revealed that C. renale cultivated in high-iron media was capable of producing pyelonephritis, but when grown on low-iron medium, these bacteria were noni...

The laboratory rat was able to serve as a model for ascending pyelonephritis after implantation of a zinc disk coated with Corynebacterium renale into the urinary bladder because it satisfied three different criteria for infection. The production of an alkaline urine and the presence of significant numbers of C. renale in the kidneys, as well as distinct pyelonephritic lesions as revealed by hi...

Dioctophyme renale is a zoonotic parasite with worldwide distribution, although its occurrence is little known. The objective here was to evaluate the presence of parasite eggs in the environment and in the urine of dogs and cats in an urban area. Soil samples and urine were evaluated respectively by means of the Caldwell-Caldwell technique and urinalysis. Out of the 100 soil samples, 3% presen...
