Detection of Pigeon Paramyxovirus Type 1 by Real-time Reverse-Transcription Polymerase Chain Reaction and Immunohistochemistry in Tissues Collected From the Patient

Tissue (No.)	PPMV-1 RNA (Ct)	PPMV-1 Antigen
Left lung (n = 2)	31	+
	21	++
Right lung (n = 3)	25	++
	23	+
	27	++
Liver (n = 1)	31	+
Left kidney (n = 1)	33	+
Bone marrow (n = 1)	37	+

Heart, esophagus, stomach, pancreas, right kidney, skin, diaphragm, and muscle tested negative for PPMV-1 RNA by real-time reverse-transcription polymerase chain reaction and for PPMV-1 antigen by immunohistochemistry; lung biopsy and lymph node biopsy tested negative for PPMV-1 antigen by immunohistochemistry.

Abbreviations: +, rare positive granules; ++, occasional positive granules; Ct, cycle threshold; PPMV-1, pigeon paramyxovirus type 1.
