| Abstract: | Abstract Extract Spontaneous glomerulonephritis has been considered an uncommon and ill-defined disease in domestic animals (Jubb and Kennedy, 1970 Jubb, K. V. F. and Kennedy, P. C. 1970. Pathology of Domestic Animals, 2nd ed., Vol. 2, 296–298. New York: Academic Press. Google Scholar]). In a survey of 236 cases of nephritis in horses, cattle, sheep, pigs and dogs, Langham and Hallman (1941 Langham, R. F. and Hallman, E. I. 1941. The incidence of glomerulonephritis in domesticated animals. J. Am. vet. Med. Ass., 99: 471–475. Google Scholar]) detected primary glomerular abnormalities in only 7. However, recent studies incorporating electron microscopic, or immunofluorescence examination, or both, of renal tissue suggest that glomerulonephritis is not uncommon. During the past 5 years it has been reported in sheep (Angus et al., 1973 Angus, K. W., Gardiner, A. C., Sykes, A. R. and Davison, A. M. 1973. A rapidly progressing mesangio-capillary glomerulonephritis in Finnish Landrace lambs. Vet. Rec., 92: 337–338. Google Scholar]), dogs (Krohn et al., 1973 Krohn, K., Jokelainen, P. I. and Sandholm, M. 1973. Light and electron microscopic observations on glomerular changes in canine interstitial nephritis. Acta path., microbiol. scand. Section A, 81: 461–473. Google Scholar]) and cats (Slauson et al., 1971 Slauson, D. O., Russell, S. W. and Schechter, R. D. 1971. Naturally occurring immune-complex glomerulonephritis in the cat. J. Path., 103: 131–133. Google Scholar]; Farrow and Huxtable, 1971 Farrow, B. R. H. and Huxtable, C. R. R. 1971. Membranous nephropathy and the nephrotic syndrome in the cat. J. comp. Path., 81: 463–467. Google Scholar]), and in 6 of 45 horses examined at a commercial slaughterhouse in the U.S.A. (Banks and Henson, 1972 Banks, K. L. and Henson, J. B. 1972.
