A male pigeon (Columba livia) dead with no clinical signs was investigated of having hepatitis. Light microscopy revealed intranuclear inclusion bodies, that ultrastructurally were shown to be herpesvirus-like particles. The particles were also found in the cytoplasm. These findings are consistent with previous reports of the disease in the pigeon. This is the first time the disease has been re...

Objective: We prospectively investigated 121 renal allograft biopsy specimens performed in our center. Methods: BKVAN was diagnosed by light microscopic examination and a positive immunohistochemistry staining of anti-SV40 large T antibody in a biopsy specimen. Results: Of the 121 patients, nine were diagnosed with BKVAN (7.4%). Nine patients with BKVN classically presents as allograft dysfunct...

Background and Aims: Inclusion body hepatitis (IBH) is one of the most important reemerging diseases in many countries with intensive poultry industries. In Iran, the etiological agent of IBH (fowl adenovirus) has not been yet confirmed. The aim of this study was the molecular detection and identification of fowl adenovirus involving IBH in chicken flocks in Iran. Materials and Methods: Polymer...

Monkey bone marrow extract when injected intracerebrally into guinea pigs or rabbits produces a distinctive encephalopathy. The Purkinje cells are severely affected, especially those at the periphery of the cerebellum. Nuclear alterations first appear, with well marked intranuclear acidophilic inclusion bodies. Similar inclusions appear at a little later stage in the ectodermal glia. The affect...

Purpose: We investigated loco-regional degenerative changes’ association with incidentally found non-traumatic vertebral body fractures of the lower thoracic and lumbar spine in older patients. Methods: The patient collective included patients age range 50 to 90 years. Vertebral bodies from T7 L5 were included. classified according Genant. following osseous extra-osseous changes included: osteo...
