A systematic study of the pathogenicity of sixty-two strains of Corynebacterium renale for laboratory white mice.

Experimental model of corynebacterium renale pyelonephritis produced in mice.

Corynebacterium renale type I (strain 115), 1.7 X 10(7) to 4.5 X 10(7) organisms, introduced intravenously into mice disappeared from the blood less than 24 h after inoculation and did not produce pyelonephritis. The same strain, 1 X 10(7) to 5 X 10(7) organisms, inoculated into the urinary bladder of mice was not recovered from the blood in any of the mice, but caused pyelonephritis accompanie...

Some properties of the pili of Corynebacterium renale.

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...

Comparison of experimental infection in mice of Corynebacterium renale piliated and non-piliated clones.

Experimental Rat model for Corynebacterium renale-induced pyelonephritis.

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...

Karyotype of NIH, C57BL/6 and Razi strains of laboratory mice (Mus musculus)

The laboratory mouse is recognized as the pre-eminent model for genetic research. Awareness of chromosomal patterns of experimental animals increases their value for a variety of different fields of study. We aimed to study mitotic chromosome preparations from NIH, C57BL/6 and Razi strains of mice, which are outbred, inbred and partially inbred laboratory mice respectively. Bone marrow cells we...
