Research Note: Simultaneous detection of infectious laryngotracheitis virus, fowlpox virus, and reticuloendotheliosis virus in chicken specimens.

Poult Sci 2021 Apr 16;100(4):100986. Epub 2021 Jan 16.

Avian Disease Division, Animal and Plant Quarantine Agency, GimCheon, Republic of Korea. Electronic address:

Infectious laryngotracheitis (ILT), fowlpox (FP), and reticuloendotheliosis are important poultry diseases caused by gallid herpesvirus 1 (ILTV), fowlpox virus (FWPV), and reticuloendotheliosis virus (REV), respectively. Coinfections with ILTV and FWPV occur naturally in chickens, and FP in its more virulent wet form is characterized by diphtheritic lesions and easily confused with ILT. Moreover, the insertion of only partial REV-LTR or a nearly full-length REV into the FWPV genome, located between the ORF 201 and ORF 203, has increased recently in wild-type field FWPV isolates.

Orthopoxvirus K3 orthologs show virus- and host-specific inhibition of the antiviral protein kinase PKR.

PLoS Pathog 2021 01 14;17(1):e1009183. Epub 2021 Jan 14.

School of Medicine, University of California Davis, Department of Medial Microbiology and Immunology, Davis, California, United States of America.

The antiviral protein kinase R (PKR) is an important host restriction factor, which poxviruses must overcome to productively infect host cells. To inhibit PKR, many poxviruses encode a pseudosubstrate mimic of the alpha subunit of eukaryotic translation initiation factor 2 (eIF2), designated K3 in vaccinia virus. Although the interaction between PKR and eIF2α is highly conserved, some K3 orthologs from host-restricted poxviruses were previously shown to inhibit PKR in a species-specific manner. Read More
