HOST-PARASITE INTERACTION IN THE RAT RENAL PELVIS

Host-parasite Interaction in the Rat Renal Pelvis

The initial interaction between bacteria and the renal pelvic epithelium may determine whether intrarenal infection occurs. A model of retrograde pyelonephritis was employed to study these events by electron microscopy. Female rats received an intravesicular inoculation of a 0.5-ml suspension of Proteus mirabilis containing 10(8) organisms. At intervals after inoculation, the kidneys were fixed...

Host extinction dynamics in a simple parasite-host interaction model.

This short article carefully formulate a simple SI model for a parasite-host interaction through the basic birth and death processes analysis. This model reveals and corrects an error in similar models studied recently by various authors. Complete mathematical investigation of this simple model shows that the host extinction dynamics can happen and the outcomes may depend on the initial conditi...

Spontaneous carcinosarcoma originating from the renal pelvis ina rat

Carcinosarcoma is a rare neoplasm composed of malignant epithelial and stromal elements, and, for rats, carcinosarcomas in the kidney have not been reported. In a long-term study to gather background data, we encountered a spontaneous carcinosarcoma originating from the renal pelvis with metastasis to the lung. At necropsy, a mass was observed in the abdominal cavity, and white nodules were sca...
