    A 1-year-old, female budgerigar showed systemic molting and severe growth retardation. Hemorrhage and infiltration of inflammatory cells, degeneration and necrosis of feather epithelial cells, and basophilic intracytoplasmic and intranuclear inclusions in feather shafts were noted. By polymerase chain reaction (PCR) analysis to detect the Psittacine beak and feather disease (PBFD) virus, positive results were yielded when the analysis targeting ORF C1 was used, but not when the traditional PCR analysis targeting ORF V1. In addition, characteristic large eosinophilic intranuclear inclusions of psittacine herpesvirus were observed in hepatocytes.The transmissibility of the variant PBFDV was recognized by experimental inoculation using an emulsion of shaft homogenates from the case bird. These results suggested that this bird developed PBFD from a variant PBFD virus as the underlying disease, and complications of Pacheco's disease made the clinical signs more severe.

    A pathologic examination was conducted on a 15-week-old wasting pig at a farm in Saitama Prefecture, Japan. At necropsy, multiple white nodules (0.2-1.0 cm in diameter) were detected on the surface of the liver and spleen, serosa of jejunum, ileum and colon, pulmonary pleura, epicardium and mesentery. Histologically, the white nodules were abscesses with gram-positive bacteria, and were surrounded by thick connective tissues. Immunohistochemically, Arcanobacterium pyogenes antigen corresponded to the organisms in the abscess. Short bacilli were isolated from the liver, spleen, kidney, heart, lung, and pleural fluid. The isolates were confirmed as A. pyogenes by biochemical analyses. Comparative 16S rRNA gene sequencing analysis of the isolates also revealed that they were likely the same species of A. pyogenes. The present case was diagnosed as swine multiple suppurative serositis caused by A. pyogenes.
