Renal disease in squirrel monkeys (Saimiri sciureus)

Renal lithiasis, pyelonephritis, and glomerulonephritis were common in our colony of Brazilian phenotype squirrel monkeys (Saimiri sciureus), with glomerulonephritis being a major cause of mortality in adult animals. Squirrel monkey glomerulonephritis was divided into four major classifications, based on light and electron microscopy, similar to those of man: focal sclerosing glomerulonephritis, membranoproliferative glomerulonephritis, membranous glomerulonephritis, and a combination of membranoproliferative and membranous glomerulonephritis.
