Bornaviruses are the only animal RNA viruses that establish a persistent infection in their host cell nucleus. Studies of bornaviruses have provided unique information about viral replication strategies and virus–host interactions. Although bornaviruses do not integrate into the host genome during their replication cycle, we and others have recently reported that there are DNA sequences derived from the mRNAs of ancient bornaviruses in the genomes of vertebrates, including humans, and these have been designated endogenous borna-like (EBL) elements. Therefore, bornaviruses have been interacting with their hosts as driving forces in the evolution of host genomes in a previously unexpected way. Studies of EBL elements have provided new models for virology, evolutionary biology and general cell biology. In this review, we summarize the data on EBL elements including what we have newly identified in eukaryotes genomes, and discuss the biological significance of EBL elements, with a focus on EBL nucleoprotein elements in mammalian genomes. Surprisingly, EBL elements were detected in the genomes of invertebrates, suggesting that the host range of bornaviruses may be much wider than previously thought. We also review our new data on non-retroviral integration of Borna disease virus.

“…Definitive diagnosis of PDD relies on characteristic histopathologies of lymphoplasmacytic infiltration in nerves and ganglia of the proventriculus, ventriculus and other gastrointestinal tract. Similar infiltrations are also often seen in the brain, spinal cord, peripheral nerves, heart and adrenal glands [1,5].…”

“…Proventricular dilatation disease (PDD) was first reported in macaws in the late 1970s and early 1980s [1,5], and as a result, it is known as macaw wasting disease. The name, PDD, is derived from the characteristic feature of the disease, i.e., dilatation of the proventriculus.…”

“…The name, PDD, is derived from the characteristic feature of the disease, i.e., dilatation of the proventriculus. The most common clinical signs of PDD are depression, weight loss, regurgitation, central nervous system signs such as ataxia, tremors and seizures and/or passage of undigested seeds in the feces, indicating a malabsorptive or maldigestive disorder [1,5]. Definitive diagnosis of PDD relies on characteristic histopathologies of lymphoplasmacytic infiltration in nerves and ganglia of the proventriculus, ventriculus and other gastrointestinal tract.…”

ABSTRACT. A 5-month-old female Citron-crested Cockatoo (Cacatua sulphurea citrinocristata) that was born and hand-reared in Japan died with suspected proventricular dilatation disease (PDD). Macroscopic and microscopic examinations of the bird revealed characteristic features of PDD, i.e., distention of the proventriculus and infiltration of lymphocytes and plasma cells in ganglia of various organs and in central and peripheral nerves. A linkage of this PDD case to infection with avian bornavirus (ABV) was documented by RT-PCR amplification of the virus genomes from the affected bird. Phylogenetic analysis revealed that the ABV identified in this study clustered into the genotype 2, which is one of the dominant ABV genotypes worldwide. To the best of our knowledge, this is the first report of a natural case of PDD associated with ABV infection in Japan.
