Investigating the natural resistance of blackfoot p-a%%KERN_ERR%%ua Haliotis iris to abalone viral ganglioneuritis using whole transcriptome analysis.

The natural resistance of New Zealand blackfoot p-a%%%%%%%%%%%%%%KERN_ERR%%KERN_ERR%%KERN_ERR%%KERN_ERR%%KERN_ERR%%KERN_ERR%%KERN_ERR%%ua Haliotis iris to infection by haliotid herpesvirus-1 (HaHV-1) and to the disease abalone viral ganglioneuritis was investigated in experimentally challenged p-aua using high throughput RNA-sequencing. HaHV-1-challenged p-aua up-regulated broad classes of genes that contained chitin-binding peritrophin-A domains, which seem to play diverse roles in the p-aua immune response. The p-aua also up-regulated vascular adhesion protein-1 (VAP-1), an important adhesion molecule for lymphocytes, and chitotriosidase-1 (CHIT-1), an immunologically important gene in mammalian immune systems.

Robust Innate Immunity of Young Rabbits Mediates Resistance to Rabbit Hemorrhagic Disease Caused by Lagovirus Europaeus GI.1 But Not GI.2.

The rabbit caliciviruses Lagovirus europaeus GI.1 and GI.2 both cause acute necrotizing hepatitis in European rabbits ().

Innate resistance of New Zealand paua to abalone viral ganglioneuritis.

The susceptibility of New Zealand paua (Haliotis iris) to infection by abalone herpesvirus (Haliotid herpesvirus 1; HaHV) and to the disease abalone viral ganglioneuritis (AVG) was determined. Infection challenges performed by intra-muscular injection and by immersion in infectious water containing HaHV demonstrated that New Zealand paua were highly resistant to infection by Haliotid herpesvirus 1 and were fully resistant to the disease AVG.

shRNAs targeting either the glycoprotein or polymerase genes inhibit Viral haemorrhagic septicaemia virus replication in zebrafish ZF4 cells.

Viral haemorrhagic septicaemia virus (VHSV) represents an important disease of finfish. To explore the potential of shRNAs to combat this disease nucleotide sequences of either the VHSV glycoprotein (G) or polymerase (L) gene were targeted. To test their function, shRNAs were expressed in zebrafish epithelial ZF-4 cells utilizing the zebrafish U6-2 promoter.

Transcriptomic analysis of common carp anterior kidney during Cyprinid herpesvirus 3 infection: Immunoglobulin repertoire and homologue functional divergence.

Cyprinid herpesvirus 3 (CyHV-3) infects koi and common carp and causes widespread mortalities. While the virus is a significant concern for aquaculture operations in many countries, in Australia the virus may be a useful biocontrol agent for pest carp. However, carp immune responses to CyHV-3, and the molecular mechanisms underpinning resistance, are not well understood.

Cyprinid herpesvirus 3 and its evolutionary future as a biological control agent for carp in Australia.

Biological invasions are a major threat to global biodiversity. Australia has experienced many invasive species, with the common carp (Cyprinus carpio L.) a prominent example.

Australian abalone (Haliotis laevigata, H. rubra and H. conicopora) are susceptible to infection by multiple abalone herpesvirus genotypes.

From 2006 to 2012, acute mortalities occurred in farmed and wild abalone (Haliotis spp.) along the coast of Victoria, Australia. The disease (abalone viral ganglioneuritis; AVG) is associated with infection by an abalone herpesvirus (AbHV).

Expression of immune-related genes of common carp during cyprinid herpesvirus 3 infection.

Fish herpesviruses and their hosts may have coevolved for 400 to 450 million yr. During this coexistence, the hosts have equipped themselves with an elaborate immune system to defend themselves from invading viruses, whereas the viruses have developed strategies to evade host immunity, including the expression of cytokine genes that have been captured from the host. Taking advantage of our experimental model for cyprinid herpesvirus 3 (CyHV-3) persistence in carp, we studied the gene expression of host and virus immune-related genes in each stage of infection: acute, persistent and reactivation phases.

Characteristics of cyprinid herpesvirus 3 in different phases of infection: implications for disease transmission and control.

Koi herpesvirus disease (KHVD) is an emerging and highly contagious viral disease of koi and common carp (Cyprinus carpio), causing mass mortalities and huge economic losses to the carp aquaculture industry. The disease has spread rapidly to 28 countries worldwide. However, mechanisms of koi herpesvirus (species Cyprinid herpesvirus 3; CyHV-3) transmission remain unclear.

Koi herpesvirus encodes and expresses a functional interleukin-10.

Koi herpesvirus (KHV) (species Cyprinid herpesvirus 3) ORF134 was shown to transcribe a spliced transcript encoding a 179-amino-acid (aa) interleukin-10 (IL-10) homolog (khvIL-10) in koi fin (KF-1) cells. Pairwise sequence alignment indicated that the expressed product shares 25% identity with carp IL-10, 22 to 24% identity with mammalian (including primate) IL-10s, and 19.1% identity with European eel herpesvirus IL-10 (ahvIL-10).

Abalone viral ganglioneuritis: establishment and use of an experimental immersion challenge system for the study of abalone herpes virus infections in Australian abalone.

In late 2005, acute mortalities occurred in abalone on farms located in Victoria, Australia. Disease was associated with infection by an abalone herpes virus (AbHV). Subsequently, starting in 2006, the disease (abalone viral ganglioneuritis; AVG) was discovered in wild abalone in Victorian open waters.

Histological and global gene expression analysis of the 'lactating' pigeon crop.

Background: Both male and female pigeons have the ability to produce a nutrient solution in their crop for the nourishment of their young. The production of the nutrient solution has been likened to lactation in mammals, and hence the product has been called pigeon 'milk'. It has been shown that pigeon 'milk' is essential for growth and development of the pigeon squab, and without it they fail to thrive.

Molecular characterisation of Australasian isolates of aquatic birnaviruses.

An aquatic birnavirus, first isolated in Australia from farmed Atlantic salmon in Tasmania in 1998, has continued to be re-isolated on an infrequent but regular basis. Due to its low pathogenicity, there has been little urgency to undertake a comprehensive characterisation of this aquatic birnavirus. However, faced with possible incursions of any new aquatic birnaviruses, specific identification and differentiation of this virus from other, pathogenic, aquatic birnaviruses such as infectious pancreatic necrosis virus (IPNV) are becoming increasingly important.

Susceptibility of domestic dogs and cats to Australian bat lyssavirus (ABLV).

The susceptibility of cats and dogs to Australian bat lyssavirus (ABLV; genotype VII) was investigated by intramuscular (IM) inoculation of 10(3.7)-10(5) 50% tissue culture infective doses (TCID(50)) of virus followed by observation of experimental animals for up to 3 months post-inoculation (pi). Each experiment also included positive and negative controls, animals inoculated with a bat variant of rabies virus (Eptesicus I, genotype I), or a 10% suspension of uninfected mouse brain, respectively.
