PHAGE.. TYPES AND THEIR EPIDEMIOLOGICAL SIGNIFICANCE
2016Co-Authors: Takashi Hiramune, Ryo YanagawaAbstract:Corynebacterium renale was recently found to be lysogenic by YANAGA WA et a1. (1968). They observed that about 2/3 strains of C. renale type I were lysogenic, and many of them produced phages similar in host range. The repre-sentative phage, designated RP 6, was studied in detail. It was found to b

Distribution of Corynebacterium renale among apparently healthy rats
Veterinary microbiology, 1996Co-Authors: T. Osanai, T. Ohyama, Naoya Kikuchi, Tatsufumi Takahashi, Noriyuki Kasai, Takashi HiramuneAbstract:We examined the distribution of Corynebacterium renale, a causative agent of urinary calculus, in clinically normal rats at 6 animal facilities in Japan. Swabs of the vulva and vaginal vestibule or prepuce of the rats were cultured for isolation of the organisms. C. renale has been isolated at only one animal facility, where cases of urinary calculus were reported several years ago. In this facility, 32% of female (43/135) and 22% of male (18/82) rats, 4-28 weeks old, were positive for C. renale. In contrast, 92 female and 169 male rats at other facilities without a history of the disease were negative for the organisms.

Assignment of the bacterial agent of urinary calculus in young rats by the comparative sequence analysis of the 16S rRNA genes of corynebacteria.
The Journal of veterinary medical science, 1995Co-Authors: Tatsufumi Takahashi, Ryo Yanagawa, Naoya Kikuchi, Noriyuki Kasai, Tsutomu Osanai, Masayoshi Tsuji, Chiaki Ishihara, Takashi HiramuneAbstract:Comparative 16S rRNA gene sequencing was used to assign four isolates of spontaneous urinary calculus in young laboratory rats. The phylogenetic relationships among the rat isolates and selected species of corynebacteria were also inferred. Based on the homology and evolutionary distance analysis, the 16S rRNA genes of the rat isolates were almost identical with that of Corynebacterium renale ATCC 19412T. Also the results of the phylogenetic analysis showed a close relationship among the isolates and C. renale, but they were clearly different from C. pilosum, C. cystitidis, C. kutscheri and Rhodococcus equi. The results of the present study and previously published biochemical data demonstrate that the organism involving urinary infections in young rats is identified to be C. renale.

Spontaneous urinary calculus in young LEW rats caused by Corynebacterium renale.
The Journal of urology, 1994Co-Authors: Tsutomu Osanai, Takashi Hiramune, Ichiro Miyoshi, Noriyuki KasaiAbstract:Spontaneous urinary calculus was observed in only 27% of female LEW rats among nine inbred strains maintained in the Institute for Animal Experimentation. The condition occurred between 3 and 9 weeks of age with loss of weight, enlargement of the os urethral externum, anuria and general marasmus. All of the affected rats died from anuria 3 to 4 days after the onset. The affected rats had one to ten infected stones or many fine crystals of sand, which consisted of magnesium ammonium phosphate, in the urinary bladder and/or urethra. Analysis of microorganisms revealed that Corynebacterium renale, known as a causative agent of bovine pyelonephritis, was the most probable candidate for producing infection stones. This is the first report that the rat is spontaneously infected with C. renale. This could be a useful animal model for human urinary calculus and also for C. renale infection in the field of veterinary science.

The Journal of urology, 1994Co-Authors: Tsutomu Osanai, Takashi Hiramune, Ichiro Miyoshi, Noriyuki KasaiAbstract:Spontaneous urinary calculus was observed in only 27% of female LEW rats among nine inbred strains maintained in the Institute for Animal Experimentation. The condition occurred between 3 and 9 weeks of age with loss of weight, enlargement of the os urethral externum, anuria and general marasmus. All of the affected rats died from anuria 3 to 4 days after the onset.
