EXTRAINTESTINAL PATHOGENIC E. COLI (EXPEC) INFECTION Figure 13-10 EXTRAINTESTINAL PATHOGENIC E. COLI (EXPEC) INFECTION A: Perinephric abscess due to E. coli shows the abscess wall in the perinephric fat tissue. B: There is pronounced acute suppurative inflammation with associated necrotic debris, in which etiologic gram-negative bacilli with typical morphology (see fig. 13-1B ) may occasionally be demonstrated with special stains.

BACILLARY DYSENTERY DUE TO SHIGELLA FLEXNERI AND SALMONELLA Figure 13-2 BACILLARY DYSENTERY DUE TO SHIGELLA FLEXNERI AND SALMONELLA A: Low-power histology of a colon biopsy shows preserved crypt architecture, mild lamina propria congestion, focal neutrophil infiltration, and superficial plasmacytosis. Note the basal crypt neutrophil exocytosis. B: Bacillary dysentery due to nontyphi Salmonella, with more prominent neutrophil infiltration, superficial/midmucosal crypt abscess formation, crypt destruction, mucin depletion, and crypt epithelial reactive change. Unlike inflammation in chronic inflammatory bowel disease, there is an absence of deep crypt abscess formation, basal plasmacytosis, and other features of chronicity.
