“…However, other potential members of the genus Gyrovirus have been recently discovered in humans and birds. These novel gyroviruses (GyVs) have been identified in human skin (human gyrovirus (HGyV) [74]) and feces (GyV3 through GyV6; [8,61,62]), chicken serum (avian gyrovirus 2 (AGV2) [66]) and meat (GyV4 and GyV7; [8]) as well as spleen and uropygial gland tissues from sea birds (GyV8; [39]). Since HGyV and AGV2 may represent the same species [61], the genus Gyrovirus should soon be updated to reflect at least eight viral species.…”

“…Most recently, novel members of the Gyrovirus genus have been discovered in diseased chicken (Rijsewijk et al, 2011), but also in human faeces (Phan et al, 2012) and in healthy blood donors as well (Biagini et al, 2013a). The positive fish samples examined in our survey originated from 142 TARJÁN et al Hungarica 62, 2014 apparently healthy individuals.…”

The negative samples of a collection, established originally for seeking new adeno-and herpesviruses in lower vertebrates, were screened for the presence of circoviruses by a consensus nested PCR targeting the gene coding for the replication-associated protein. Six fish samples representing five species, namely asp (Aspius aspius), roach (Rutilus rutilus), common bream (Abramis brama), round goby (Neogobius melanostomus) and monkey goby (Neogobius fluviatilis), as well as three frog samples were found positive for circoviral DNA. Sequence analysis of the amplicons indicated the presence of three novel putative circo-like viruses and a circovirus in Hungarian fishes and one novel circovirus in a common toad (Bufo bufo), and another one in a dead and an alive specimen of green tree frog (Litoria caerulea), respectively. In phylogeny reconstruction, the putative bream circovirus clustered together with circoviruses discovered in other cyprinid fishes recently. Three other piscine circoviral sequences appeared closest to sequences derived from different environmental samples. Surprisingly, the nucleotide sequence derived from two fish samples (a bream and a monkey goby) proved to be from porcine circovirus 2 (PCV2), almost identical to a sequence detected in Sweden previously. This is the first report on the detection of PCV2 in fish and circoviral DNA in amphibian hosts.

“…Sarker et al (2014) reported quasispecies variants and recombination events in an outbreak of emerging beak and feather disease virus (BFDV) that caused psittacine beak and feather disease. Chicken anemia virus (CAV) was the only known representative of the Gyrovirus genus, novel avian gyrovirus 2 (AGV2) and genetic variants of AGV2 were reported in chickens (Rijsewijk et al, 2011;Dos Santos et al, 2012). Avian orthoreoviruses have been associated with a variety of diseases in chickens.…”

Summary. -Increased globalisation, climatic changes and wildlife-livestock interface led to emergence of novel viral pathogens or zoonoses that have become serious concern to avian, animal and human health. High biodiversity and bird migration facilitate spread of the pathogen and provide reservoirs for emerging infectious diseases. Current classical diagnostic methods designed to be virus-specific or aim to be limited to group of viral agents, hinder identifying of novel viruses or viral variants. Recently developed approaches of next-generation sequencing (NGS) provide culture-independent methods that are useful for understanding viral diversity and discovery of novel virus, thereby enabling a better diagnosis and disease control. This review discusses the different possible steps of a NGS study utilizing sequence-independent amplification, high-throughput sequencing and bioinformatics approaches to identify novel avian viruses and their diversity. NGS lead to the identification of a wide range of new viruses such as picobirnavirus, picornavirus, orthoreovirus and avian gamma coronavirus associated with fulminating disease in guinea fowl and is also used in describing viral diversity among avian species. The review also briefly discusses areas of viral-host interaction and disease associated causalities with newly identified avian viruses.
