Pelophylax ridibundus infected with A. ranae. Small intestine. a. Destruction of villi tissue architecture (DVA), epithelial hyperplasia (EH), inflammatory infiltrate (II). b. Around the acanthocephalans (Ac.), the mucosa is injured (IM), with abundant inflammatory cell infiltrate(ICI) in glandular crypts (GC) and villous fibrosis (VF). c. The effect of parasitism consists in partial or total destruction of the villi (VD) the disappearance of the mucosal epithelium (DME) and discovery of the conjunctival axis (DCA), and general atrophy. d. Catarrhal jejunitis: hyperplasia and edematous infiltration of the submucosa and musculosa (HEM), ulcerative areas (UA) and inflammatory infiltrate, necrobiosis and cell necrosis processes, and areas with total atrophy (TA) of the intestinal mucosa (Trichormic Masson stain x 100, 200).
