Pyelonephritis was produced in 75 white rats by applying a 24-hour ligature on the ureter and by intravenous injection of a suspension of 5X10(9) cells of a stable Proteus mirabilis L-form. Pyelonephritis was proved microscopically in 44% of the animals. The revertants of the introduced L-form play an etiological role in the development of the infection. The stability of the pathohistological findings makes this model suitable for the purpose of experimental chemotherapy.

UI MeSH Term Description Entries
D007740 L Forms Bacterial variants, unable to form a complete cell wall, which are formed in cultures by various bacteria; granules (L bodies) appear, unite, and grow into amorphous bodies which multiply and give rise to bacterial cells morphologically indistinguishable from the parent strain.
D011513 Proteus mirabilis A species of gram-negative, facultatively anaerobic, rod-shaped bacteria that is frequently isolated from clinical specimens. Its most common site of infection is the urinary tract.
D011704 Pyelonephritis Inflammation of the KIDNEY involving the renal parenchyma (the NEPHRONS); KIDNEY PELVIS; and KIDNEY CALICES. It is characterized by ABDOMINAL PAIN; FEVER; NAUSEA; VOMITING; and occasionally DIARRHEA. Necrotizing Pyelonephritis,Pyelonephritis, Acute Necrotizing,Pyelonephritides
