Possible microbiological infections in the intestinal tissue. a Fungal spores (purple red, yellow arrows) but without pseudohypha were identified by PAS staining (400X), b Fungal spores (black, green arrows) were identified by GMS staining (400X), c Gram staining revealed positive cocci (purple, green arrow, 1000X). d Ziehl–Neelsen stain (400X) did not identified Mycobacterium tuberculosis. Immunohistochemistry of HSV (e 400X) and CMV (f 400X) and in situ hybridization of EBV (g 400X) did not showed signal
