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.

USE OF SPECIAL STAINS IN THE DIAGNOSIS OF INFECTIOUS DISEASES Figure 1-2 USE OF SPECIAL STAINS IN THE DIAGNOSIS OF INFECTIOUS DISEASES A,B: Bone marrow H&E (A) and Grocott methenamine silver (B) stains. The latter shows numerous budding Histoplasma capsulatum yeasts. C–E: H&E stain (C,D) on a pituitary gland specimen showing histologic findings suspicious for tissue pathogens. A strongly positive von Kossa calcium stain (E), however, confirms the suspicious deposits as calcifications and excludes infectious microorganisms.
