A study on the infection status and transmission of avian leukosis virus subgroup J in Hy-line brown roosters.

Arch Virol 2022 May 23. Epub 2022 May 23.

College of Veterinary Medicine, China Agricultural University, Beijing, China.

Avian leukosis virus subgroup J (ALV-J) is the most prevalent subgroup in chickens and exhibits increased pathogenicity and stronger horizontal and vertical transmission ability among different breeds. Although vertical transmission of ALV-J from infected hens through artificial insemination has been inferred from the detection of the p27 antigen in swabs and serum, there has been no further research on the transmission pattern of ALVs in roosters. In the present study, the positive rate of ALV increased significantly in an indigenous flock after detecting the p27 antigen via enzyme-linked immunosorbent assay (ELISA) and virus isolation in DF-1 cells.

Arch Virol 2022 May 14. Epub 2022 May 14.

Department of Plant Pathology, Universidade de Brasília (UnB), Brasília-DF, 70910-900, Brazil.

The natural occurrence of mixed infections and large populations of the polyphagous vector (Bemisia tabaci) are the main factors associated with the intensification of the genetic flow among begomoviruses in Neotropical areas, contributing to the emergence of novel recombinants. Here, high-throughput sequencing and metagenomic analyses were employed to discover and characterize a novel recombinant bipartite begomovirus, tentatively named "macroptilium bright yellow interveinal virus" (MaBYIV) in the weed Macroptilium erythroloma (Fabaceae). Recombination signals were detected in MaBYIV, involving bean golden mosaic virus (BGMV) and tomato mottle leaf curl virus (ToMoLCV) genome components. Read More

A novel E198K substitution in the PA gene of influenza A virus with reduced susceptibility to baloxavir acid.

Arch Virol 2022 May 5. Epub 2022 May 5.

Satoshi Ōmura Memorial Research Institute and Graduate School for Infection Control, Kitasato University, 5-9-1 Shirokane, Minato-ku, Tokyo, 108-8641, Japan.

Baloxavir acid (BXA), the active compound in baloxavir marboxil (BXM), reduces the propagation of influenza A and B viruses by inhibiting the cap-dependent endonuclease activity of the polymerase acidic (PA) subunit. Although BXM has been used to treat influenza virus infections, recently, there has been general concern about the emergence of viruses with low susceptibility to BXA. Here, we identified a novel PA subunit substitution, PA E198K, that reduced susceptibility to BXA. Read More

Viruses are, by far, the most abundant biological entities on earth. They are found in all known ecological niches and are the causative agents of many important diseases in plants and animals. From an evolutionary point of view, since viruses do not share any orthologous genes, there is a general consensus that they are polyphyletic; that is, they do not have a common ancestor. Read More
