Figure 8: kideny of fish infected with marked granular and vacuolar degeneration as well as necrosis of the renal tubular
epithelial lining, some of which appeared completely hyalinized and atrophied glomerular tufts. (H&E X400)
Figure 9: Kideny of S. dygalactiae infected fish showing completely necrosed and hyalized renal tubules some of which
replaced by inflammatory cells. (H&E X400)
Figure 10: Kideny of E. gallinarum infected fish showing; marked desquamation of the epithelal lining leaving the
basement membrane, notice the congestion, atophy and hypercellularity of the glomerular tufts. (H&E X400)
Figure 11: kideny of fish infected with E. gallinarum showing marked hypercellularity of the glomerular tufts and focal
interstitial mononuclear inflammatory cells with few esinophilic cells infiltration in the interstitial tissue. (H&E X400)
Figure 12: kideny of fish infected with L. garvieae presenting; diffuse interstitial inflammatory cells infitation among the
necrosed tubules. (H&E X200)
