Abstract
Bovine adenovirus type 7 (BAdV-7) is one of the most important respiratory and enteric pathogens in the cattle industry. Although live attenuated vaccines are used to control the virus in Japan, limited information is available on the genomic regions that determine viral pathogenicity. We determined the complete genome sequence of the attenuated BAdV-7 strain TS-GT. The genome is 30,052 bp long and contains 45-bp inverted terminal repeats and 30 predicted genes. A genome sequence comparison showed that 99.9% of the TS-GT genome is identical to the prototypic and pathogenic BAdV-7 strain Fukuroi; however, the TS-GT genome contains a novel mutation and four indels. We describe here potential relationships between these genomic changes and the biological characteristics of BAdV-7.

Abstract
Fowl adenovirus (FAdV) is a double-stranded DNA virus with a non-enveloped structure comprising three major proteins known as hexon, penton, and fiber. Molecular analysis which emphasizes on hexon and fiber proteins is currently the major focus of curiosity for FAdV antigenicity and pathogenicity. Recently, disease outbreaks associated with FAdV infections such as inclusion body hepatitis, hepatitis hydropericardium syndrome, and gizzard erosion, were commonly reported and continue to increase worldwide. Studies on the virulence gene of the virus were intensively conducted to provide a better understanding on the role of these major capsid proteins in the development of a safe and effective vaccine against the disease in the poultry industry. This paper highlights the variations of the fiber and hexon genes, their importance in genotypes and serotypes differentiation, and infectivity between FAdV strains. It appears that the L1 loop of hexon and the knob of fiber genes are the infectivity markers for FAdV infection. The fiber-2 protein plays a major role in FAdV pathogenicity than the hexon protein, while the fiber-1 protein is important for viral replication and assembly, regardless of virulence capability instead of infectivity. The hexon protein plays a major role in virus infectivity and tissue tropism. These findings could further enhance the knowledge of FAdV strains’ classification and evolution, diagnosis, and strategies to prevent and control FAdV infection and outbreaks in chicken farms.

Abstract
Wild birds harbour a large number of adenoviruses that remain uncharacterised with respect to their genomic organisation, diversity, and evolution within complex ecosystems. Here, we present the first complete genome sequence of an atadenovirus from a passerine bird that is tentatively named Passerine adenovirus 1 (PaAdV-1). The PaAdV-1 genome is 39,664 bp in length, which was the longest atadenovirus to be sequenced, to the best of our knowledge, and contained 42 putative genes. Its genome organisation was characteristic of the members of genus Atadenovirus; however, the novel PaAdV-1 genome was highly divergent and showed the highest sequence similarity with psittacine adenovirus-3 (55.58%). Importantly, PaAdV-1 complete genome was deemed to contain 17 predicted novel genes that were not present in any other adenoviruses sequenced to date, with several of these predicted novel genes encoding proteins that harbour transmembrane helices. Subsequent analysis of the novel PaAdV-1 genome positioned phylogenetically to a distinct sub-clade with all others sequenced atadenoviruses and did not show any obvious close evolutionary relationship. This study concluded that the PaAdV-1 complete genome described here is not closely related to any other adenovirus isolated from avian or other natural host species and that it should be considered a separate species.

Abstract
Bearded dragon adenovirus 1 (BDAdV-1), also known as agamid adenovirus 1, has been described worldwide as a prevalent infectious agent of the inland bearded dragon (Pogona vitticeps), the most common squamate exotic pet reptile. Previous limited sequence data of the adenoviral DNA polymerase and hexon genes indicated that BDAdV-1 is a member of genus Atadenovirus family Adenoviridae. Atadenoviruses infect ruminants, marsupials, testudine reptiles and birds, yet the genus has been shown to be of squamate reptile origin. Here, we report a screening survey along with the complete genome sequence of BDAdV-1, derived directly from the sample of a deceased juvenile dragon showing central nervous system signs prior to passing. The BDAdV-1 genome is 35,276 bp and contains 32 putative genes. Its genome organization is characteristic of the members of genus Atadenovirus, however, a divergent LH3 gene indicates structural interactions of different nature compared to other genus members such as snake adenovirus 1. We identified five novel open reading frames (ORFs), three of which encode proteins of the C-type lectin-like domain (CTLD) superfamily. ORF3 has a CTLD group II-like domain architecture displaying structural similarity with natural killer cell surface receptors and with an alphaherpesviral virulence factor gene for neurotropism, UL45. ORF4 and 6 are extremely long compared to typical adenoviral right-end genes and possibly encode members of the CTLD superfamily with novel, previously undescribed domain architectures. BDAdV-1 is the hitherto most divergent member of genus Atadenovirus providing new insights on adenoviral diversity, evolution and pathogenesis.

Abstract
Porcine adenoviruses (PAdVs) are classified into three species, PAdV-A, PAdV-B, and PAdV-C. The genomes of PAdV-A and PAdV-C have been well characterized. However, the genome of PAdV-B has never been completely sequenced, and the epidemiology of PAdV-B remains unclear. In our study, we have identified a novel strain of PAdV-B, named PAdV-B-HNU1, in porcine samples collected in China by viral metagenomic assay and general PCR. The genome of PAdV-B-HNU1 is 31,743 bp in length and highly similar to that of California sea lion adenovirus 1 (C. sea lion AdV-1), which contains typical mastadenoviral structures and some unique regions at the carboxy-terminal end. Especially, PAdV-B-HNU1 harbors a dUTPase coding region not clustering with other mastadenoviruses except for C. sea lion AdV-1 and a fiber coding region homologous with galectin 4 and 9 of animals. However, the variance of GC contents between PAdV-B-HNU1 (55%) and C. sea lion AdV-1 (36%) indicates their differential evolutionary paths. Further epidemiologic study revealed a high positive rate (51.7%) of PAdV-B-HNU1 in porcine lymph samples, but low positive rates of 10.2% and 16.1% in oral swabs and rectal swabs, respectively. In conclusion, this study characterized a novel representative genome of a lymphotropic PAdV-B with unique evolutionary origin, which contributes to the taxonomical and pathogenic studies of PAdVs.

Abstract
Avian adenoviruses (AdVs) are a very diverse group of pathogens causing diseases in poultry and wild birds. Wild birds, endangered by habitat loss and habitat fragmentation in the tropical forests, are recognised to play a role in the transmission of various AdVs. In this study, two novel, hitherto unknown AdVs were described from faecal samples of smooth-billed ani and tropical screech owl. The former was classified into genus Aviadenovirus, the latter into genus Atadenovirus, and both viruses most probably represent new AdV species as well. These results show that there is very limited information about the biodiversity of AdVs in tropical wild birds, though viruses might have a major effect on the population of their hosts or endanger even domesticated animals. Surveys like this provide new insights into the diversity, evolution, host variety, and distribution of avian AdVs.

Abstract
Adenoviruses (AdVs) infect representatives of numerous species from almost every major vertebrate class, albeit their incidence shows great variability. AdVs infecting birds, reptiles, and bats are the most common and diverse, whereas only one AdV has been so far isolated both from fish and amphibians. The family Adenoviridae is divided into five genera, each corresponding to an independent evolutionary lineage that supposedly coevolved with its respective vertebrate hosts. Members of genera Mastadenovirus and Aviadenovirus seem to infect exclusively mammals and birds, respectively. The genus Ichtadenovirus includes the single known AdV from fish. The majority of AdVs in the genus Atadenovirus originated from squamate reptiles (lizards and snakes), but also certain mammalian and avian AdVs are classified within this genus. The genus Siadenovirus contains the only AdV isolated from frog, along with numerous avian AdVs. In turtles, members of a sixth AdV lineage have been discovered, pending official recognition as an independent genus. The most likely scenario for AdV evolution includes long-term cospeciation with the hosts, as well as occasional switches between closely or, rarely, more distantly related hosts.

Abstract
Viruses have been infecting their host cells since the dawn of life, and this extremely long-term coevolution gave rise to some surprising consequences for the entire tree of life. It is hypothesised that viruses might have contributed to the formation of the first cellular life form, or that even the eukaryotic cell nucleus originates from an infection by a coated virus. The continuous struggle between viruses and their hosts to maintain at least a constant fitness level led to the development of an unceasing arms race, where weapons are often shuttled between the participants. In this literature review we try to give a short insight into some general consequences or traits of virus–host coevolution, and after this we zoom in to the viral clades of adenoviruses, herpesviruses, nucleo-cytoplasmic large DNA viruses, polyomaviruses and, finally, circoviruses.

Abstract
Duck adenovirus 3 (DAdV-3) is a newly identified duck adenovirus that has recently emerged in China. The incidence of duck infection caused by this virus is very high, with very large economic losses to the poultry industry. Thus, there is an urgent need for a serological assay for the specific detection of DAdV-3. To this end, prokaryotic expression of the fiber2 protein of DAdV-3 was used as a coating antigen to establish an indirect enzyme linked immunosorbent assay (ELISA) method for the specific detection of antibodies against DAdV-3. The method was found to be specific, repeatable and more sensitive than the agarose gel precipitation test (AGP). This indirect ELISA method based on the recombinant fiber2 protein may be used for the clinical detection of DAdV-3 infection and for monitoring antibody levels after vaccine immunization and is of great significance for the effective prevention and control of the disease.

Abstract
The Brazilian Cerrado fauna shows very wide diversity and can be a potential viral reservoir. Therefore, the animal's susceptibility to some virus can serve as early warning signs of potential human virus diseases. Moreover, the wild animal virome of this biome is unknown. Based on this scenario, high-throughput sequencing contributes a robust tool for the identification of known and unknown virus species in this environment. In the present study, faeces samples from cerrado birds (Psittacara leucophthalmus, Amazona aestiva, and Sicalis flaveola) and mammals (Didelphis albiventris, Sapajus libidinosus, and Galictis cuja) were collected at the Veterinary Hospital, University of Brasília. Viral nucleic acid was extracted, submitted to random amplification, and sequenced by Illumina HiSeq platform. The reads were de novo assembled, and the identities of the contigs were evaluated by Blastn and tblastx searches. Most viral contigs analyzed were closely related to bacteriophages. Novel archaeal viruses of the Smacoviridae family were detected. Moreover, sequences of members of Adenoviridae, Anelloviridae, Circoviridae, Caliciviridae, and Parvoviridae families were identified. Complete and nearly complete genomes of known anelloviruses, circoviruses, and parvoviruses were obtained, as well as putative novel species. We demonstrate that the metagenomics approach applied in this work was effective for identification of known and putative new viruses in faeces samples from Brazilian Cerrado fauna.

Abstract
Adenoviruses (AdVs) infect a wide range of hosts, and they have undergone recent and ancient host transfers multiple times. In reptiles, AdVs have been found in many captive individuals, and have been implicated in morbidity and mortality in several species. Yet the pathogenicity, transmission, phylogenetic distribution, and source of AdVs in the environment are still unknown. We therefore chose to opportunistically sample deceased captive Anolis sagrei individuals that were collected from different populations in the Bahamas and the Cayman Islands, as well as fecal samples from one island population, to explore the disease dynamics and diversity of adenovirus infecting A. sagrei populations. We found that adenovirus infection was present in our captive colony at low prevalence (26%), and was likely not the primary cause of observed morbidity and mortality. Among the 10 individuals (out of 38 sampled) which tested positive for adenovirus, we identified four adenovirus clades, several of which are distantly related, despite the close relationships of the A. sagrei host populations. These results suggest that while adenovirus may not be highly prevalent in the wild, it is present at low levels across much of the range of A. sagrei. It may undergo frequent host switching across both deep and shallow host divergences.

Abstract
Background Egg drop syndrome (EDS), caused by the adenovirus “egg drop syndrome virus” (EDSV) causes severe economic losses through reduced egg production in breeder and layer flocks. The diagnosis of EDSV has been done by molecular tools since its complete genome sequence was identified. In order to enhance the capabilities of the real-time fluorescence loop-mediated isothermal amplification (RealAmp) assay, we aimed to apply the method for direct detection of the EDSV without viral DNA extraction. In order to detect the presence of the EDSV DNA, three pairs of primers were designed, from the conserved region of fiber gene of the EDSV. Results For our assay, test and control samples were directly used in the reaction mixture in 10-fold serial dilution. The target DNA was amplified at 65 °C, which yield positive results in a relatively short period of 40–45 min. The method reported in this study is highly sensitive as compared to polymerase chain reaction (PCR) and showed no sign of cross-reactivity or false positive results. The RealAmp accomplished specific identification of EDSV among a variety of poultry disease viruses. Conclusions The direct RealAmp can be used to detect the presence of EDSV. As our result showed, the RealAmp method could be suitable for the direct detection of other DNA viruses.

Abstract
Egg drop syndrome virus (EDSV) can markedly decrease egg production in laying hens. Duck is the natural host of EDSV. EDSV derived from ducks abrogate egg drop in laying hens. We have previously confirmed that duck-derived EDSVs have a variety of replication activities in chick embryo liver (CEL) cells. However, it is currently unclear whether duck-derived EDSV could display tropism and adaptation in laying hens. This study assessed whether duck-derived EDSV can adapt to laying hens, and estimated the inducing factors. Complete genome sequences of duck-derived EDSVs (D11-JW-012, D11-JW-017, and D11-JW-032 isolates) with various replication efficiency in CEL cells and C10-GY-001 isolate causing disease in laying hens were analyzed to find their differences. Phylogenetic analysis of complete genome sequence revealed that C10-GY-001, D11-JW-032, and strain 127 virus as vaccine were clustered into the same group, with D11-JW-012 and D11-JW-017 clustered in another group. Comparison between D11-JW-012 isolate that poorly replicated and D11-JW-017 isolate that replicated well in CEL cells in same cluster revealed six amino acid differences on IVa2, DNA polymerase, endopeptidase, and DNA-binding protein. These amino acids might be key candidates enhancing cellular tropism in chicken. When the pathogenicities of these isolates in laying hens were compared, D11-JW-032 showed severe signs similar to 127 virus, D11-JW-017 showed intermediate signs, while D11-JW-012 showed almost no sign. Eleven amino acids differed between D11-JW-032 and D11-JW-017, and 17 amino acids were different between D11-JW-032 and D11-JW-012. These results suggest that EDSVs derived from ducks have various pathogenicities in laying hens. Key amino acid candidates might have altered their affinity to tropism of laying hens, causing difference pathogenicities.

Abstract
1. Infectious diseases have a large impact on poultry health and economics. Elucidating the pathogenesis of a certain disease is crucial to implement control strategies. 2. Multiplication of a pathogen and its characterisation in vitro are basic requirements to perform experimental studies. However, passaging of the pathogen in vitro can influence the pathogenicity, a process targeted for live vaccine development, but limits the reproduction of clinical signs. 3. Numerous factors can influence the outcome of experimental infections with some importance on the pathogen, application route and host as exemplarily outlined for Histomonas meleagridis, Gallibacterium anatis and fowl aviadenoviruses (FAdVs). 4. In future, more comprehensive and detailed settings are needed to obtain as much information as possible from animal experiments. Processing of samples with modern diagnostic tools provides the option to closely monitor the host–pathogen interaction.

Abstract
Here, we report the results of a large-scale PCR survey on the prevalence and diversity of adenoviruses (AdVs) in samples collected randomly from free-living reptiles. On the territories of the Guadarrama Mountains National Park in Central Spain and of the Chafarinas Islands in North Africa, cloacal swabs were taken from 318 specimens of eight native species representing five squamate reptilian families. The healthy-looking animals had been captured temporarily for physiological and ethological examinations, after which they were released. We found 22 AdV-positive samples in representatives of three species, all from Central Spain. Sequence analysis of the PCR products revealed the existence of three hitherto unknown AdVs in 11 Carpetane rock lizards (Iberolacerta cyreni), nine Iberian worm lizards (Blanus cinereus), and two Iberian green lizards (Lacerta schreiberi), respectively. Phylogeny inference showed every novel putative virus to be a member of the genus Atadenovirus. This is the very first description of the occurrence of AdVs in amphisbaenian and lacertid hosts. Unlike all squamate atadenoviruses examined previously, two of the novel putative AdVs had A+T rich DNA, a feature generally deemed to mirror previous host switch events. Our results shed new light on the diversity and evolution of atadenoviruses.

Abstract
Antarctica is considered a relatively uncontaminated region with regard to the infectious diseases because of its extreme environment, and isolated geography. For the genetic characterization and molecular epidemiology of the newly found penguin adenovirus in Antarctica, entire genome sequencing and annual survey of penguin adenovirus were conducted. The entire genome sequences of penguin adenoviruses were completed for two Chinstrap penguins (Pygoscelis antarctica) and two Gentoo penguins (Pygoscelis papua). The whole genome lengths and G+C content of penguin adenoviruses were found to be 24,630-24,662 bp and 35.5-35.6%, respectively. Notably, the presence of putative sialidase gene was not identified in penguin adenoviruses by Rapid Amplification of cDNA Ends (RACE-PCR) as well as consensus specific PCR. The penguin adenoviruses were demonstrated to be a new species within the genus Siadenovirus, with a distance of 29.9-39.3% (amino acid, 32.1-47.9%) in DNA polymerase gene, and showed the closest relationship with turkey adenovirus 3 (TAdV-3) in phylogenetic analysis. During the 2008-2013 study period, the penguin adenoviruses were annually detected in 22 of 78 penguins (28.2%), and the molecular epidemiological study of the penguin adenovirus indicates a predominant infection in Chinstrap penguin population (12/30, 40%). Interestingly, the genome of penguin adenovirus could be detected in several internal samples, except the lymph node and brain. In conclusion, an analysis of the entire adenoviral genomes from Antarctic penguins was conducted, and the penguin adenoviruses, containing unique genetic character, were identified as a new species within the genus Siadenovirus. Moreover, it was annually detected in Antarctic penguins, suggesting its circulation within the penguin population.

Abstract
Egg-drop syndrome (EDS) virus is an avian adenovirus that causes a sudden drop in egg production and in the quality of the eggs when it infects chickens, leading to substantial economic losses in the poultry industry. Inactivated EDS vaccines produced in embryonated duck eggs or cell culture systems are available for the prophylaxis of EDS. However, recombinant subunit vaccines that are efficacious and inexpensive are a desirable alternative. In this study, we engineered chimeric fusion proteins in which the trimeric fiber knob domain lacking the triple β-spiral motif in the fiber shaft region was genetically fused to trimeric coiled coils, such as those of the engineered form of the GCN4 leucine zipper peptide or chicken cartilage matrix protein (CMP). The fusion proteins were expressed predominantly as soluble trimeric proteins in Escherichia coli at levels of 15-80mg/L of bacterial culture. The single immunization of chickens with the purified fusion proteins, at a dose equivalent to 10μg of the knob moiety, elicited serum antibodies with high hemagglutination inhibition (HI) activities, similar to those induced by an inactivated EDS vaccine. A dose-response analysis indicated that a single immunization with as little as 1μg of the knob moiety of the CMP-knob fusion protein was as effective as the inactivated vaccine in inducing antibodies with HI activity. The immunization of laying hens had no apparent adverse effects on egg production and effectively prevented clinical symptoms of EDS when the chickens were challenged with pathogenic EDS virus. This study demonstrates that the knob domain lacking the shaft sequence but fused to a trimeric coiled coil is a promising candidate subunit vaccine for the prophylaxis of EDS in chickens.

Abstract
Bats carry diverse RNA viruses, some of which are responsible for human diseases. Compared to bat-borne RNA viruses, relatively little information is known regarding bat-borne DNA viruses. In this study, we isolated and characterized three novel bat adenoviruses (BtAdV WIV9-11) from Rhinolophus sinicus. Their genomes, which are highly similar to each other but distinct from those of previously sequenced adenoviruses (AdVs), are 37 545, 37 566 and 38 073 bp in size, respectively. An unusually large E3 gene was identified in their genomes. Phylogenetic and taxonomic analyses suggested that these isolates represent a distinct species of the genus Mastadenovirus. Cell susceptibility assays revealed a broad cell tropism for these isolates, indicating that they have a potentially wide host range. Our results expand the understanding of genetic diversity of bat AdVs.

Abstract
This study aimed to characterize a novel adenovirus (AdV) isolated from diseased Muscovy ducks in China. After the AdV was successfully propagated in duck embryo fibroblasts, the morphological and physicochemical properties of the virions were studied by electron microscopy and different tests. The results of the analyses were in conformity with AdV properties. The full genome sequence was determined and analyzed. The new isolate (named CH-GD-12-2014) shared over 91% sequence identity with duck AdV-2 representing the species Duck aviadenovirus B. The most important distinguishing feature between the two DAdV strains was the presence of a second fiber gene in the Chinese isolate. Phylogeny reconstruction confirmed the affiliation of the virus with goose and duck AdVs in the genus Aviadenovirus. Experimental infection resulted in embryo death, and intramuscular inoculation provoked morbidity and mortality among ducks and chickens.

A novel psittacine adenovirus identified during an outbreak of avian chlamydiosis and human psittacosis: zoonosis associated with virus-bacterium coinfection in birds. PLoS Negl Trop Dis 2014; 8:e3318.

Abstract
Chlamydophila psittaci is found worldwide, but is particularly common among psittacine birds in tropical and subtropical regions. While investigating a human psittacosis outbreak that was associated with avian chlamydiosis in Hong Kong, we identified a novel adenovirus in epidemiologically linked Mealy Parrots, which was not present in healthy birds unrelated to the outbreak or in other animals. The novel adenovirus (tentatively named Psittacine adenovirus HKU1) was most closely related to Duck adenovirus A in the Atadenovirus genus. Sequencing showed that the Psittacine adenovirus HKU1 genome consists of 31,735 nucleotides. Comparative genome analysis showed that the Psittacine adenovirus HKU1 genome contains 23 open reading frames (ORFs) with sequence similarity to known adenoviral genes, and six additional ORFs at the 3' end of the genome. Similar to Duck adenovirus A, the novel adenovirus lacks LH1, LH2 and LH3, which distinguishes it from other viruses in the Atadenovirus genus. Notably, fiber-2 protein, which is present in Aviadenovirus but not Atadenovirus, is also present in Psittacine adenovirus HKU1. Psittacine adenovirus HKU1 had pairwise amino acid sequence identities of 50.3-54.0% for the DNA polymerase, 64.6-70.7% for the penton protein, and 66.1-74.0% for the hexon protein with other Atadenovirus. The C. psittaci bacterial load was positively correlated with adenovirus viral load in the lung. Immunostaining for fiber protein expression was positive in lung and liver tissue cells of affected parrots, confirming active viral replication. No other viruses were found. This is the first documentation of an adenovirus-C. psittaci co-infection in an avian species that was associated with a human outbreak of psittacosis. Viral-bacterial co-infection often increases disease severity in both humans and animals. The role of viral-bacterial co-infection in animal-to-human transmission of infectious agents has not received sufficient attention and should be emphasized in the investigation of disease outbreaks in human and animals.

Abstract
Adenoviruses (family Adenoviridae) infect various organ systems and cause diseases in a wide range of host species. In this study, we examined multiple tissues from Chinstrap penguins (Pygoscelis antarctica), collected in Antarctica during 2009 and 2010, for the presence of novel adenoviruses by PCR. Analysis of a 855-bp region of the hexon gene of a newly identified adenovirus, designated Chinstrap penguin adenovirus 1 (CSPAdV-1), showed nucleotide (amino acid) sequence identity of 71.8% (65.5%) with South Polar skua 1 (SPSAdV-1), 71% (70%) with raptor adenovirus 1 (RAdV-1), 71.4% (67.6%) with turkey adenovirus 3 (TAdV-3) and 61% (61.6%) with frog adenovirus 1 (FrAdV-1). Based on the genetic and phylogenetic analyses, CSPAdV-1 was classified as a member of the genus, Siadenovirus. Virus isolation attempts from kidney homogenates in the MDTC-RP19 (ATCC® CRL-8135™) cell line were unsuccessful. In conclusion, this study provides the first evidence of new adenovirus species in Antarctic penguins.

Abstract
There are eight species established for aviadenoviruses: Fowl adenovirus A–E, Goose adenovirus A, Falcon adenovirus A and Turkey adenovirus B. The aim of this study was to sequence and analyse the complete genomes of turkey adenovirus 4 (TAdV-4) and TAdV-5 (strain 1277BT) in addition to almost two-thirds of the genome of another TAdV-5 strain (strain D1648). By applying next-generation sequencing, the full genomes were found to be 42 940 and 43 686 bp and the G+C content was 48.5 and 51.6 mol% for TAdV-4 and TAdV-5, respectively. One fiber gene was identified in TAdV-4, whereas two fiber genes were found in TAdV-5. The genome organization of TAdV-4 resembled that of fowl adenovirus 5 (FAdV-5), but it had ORF1C near the left end of the genome. TAdV-4 also had five 123 bp tandem repeats followed by five 33 bp tandem repeats, but they occurred before and not after ORF8, as in several fowl adenoviruses. The genome organization of TAdV-5 was almost the same as that of FAdV-1 but with a possible difference in the splicing pattern of ORF11 and ORF26. Phylogenetic analyses and G+C content showed differences that seem to merit the establishment of two new species within the genus Aviadenovirus: Turkey adenovirus C (for TAdV-4) and Turkey adenovirus D (for TAdV-5). Our analyses suggest a common evolutionary origin of TAdV-5 and FAdV-1.

Comparison of fiber gene sequences of inclusion body hepatitis (IBH) and non-IBH strains of serotype 8 and 11 fowl adenoviruses. Virus Genes 2013; 48:74-80.

Abstract
Fowl adenoviruses (FAdVs) are common in broiler operations, and the most frequently isolated FAdVs belong to serotypes 1, 8, and 11. Serotype 1 viruses are considered nonpathogenic. While some serotype 8 and 11 viruses cause inclusion body hepatitis (IBH), these virus serotypes can also be isolated from non-IBH cases. The fiber protein is one of the major constituents of the adenoviral capsid, involved in virus entry, and it has been implicated in the variation of virulence of FAdVs. The fiber gene sequences of four FAdV-8 and four FAdV-11 isolates from both IBH and non-IBH cases were determined and analyzed for a possible association of the fiber gene sequence in virulence. The fiber protein can be divided into tail, shaft, and head domains comprising some specific features. The conserved "RKRP" sequence motif (aa 17-aa 20) fit the consensus sequence predicted for the nuclear localization signal, while the "VYPF" motif (aa 53-aa 56), involved in the penton base interaction, was also found. Similar to mammalian adenoviruses, 17 pseudo-repeats with an average length of 16 aa were detected in the FAdV-8 fiber shaft region, while 20 pseudo-repeats with an average length of 18 aa were found in FAdV-11 fibers. There was a 144-147 nt difference between the fiber genes of the two FAdV serotypes. In the shaft region, the TLWT motif that marks the beginning of the fiber head domain of the mastadenovirus was not evident among examined FAdVs. The FAdV-11 isolates had 99.1 % aa sequence identity and 99.3 % similarity to each other, and there was no conserved aa substitution within the fibers. The FAdV-8 fiber proteins showed an overall lower, 89 % aa sequence identity and 93.4 % similarity, to each other and 22 nonsynonymous mutations were detected. Virulence markers were not detected in the analyzed fiber gene sequences of the different pathotypes of the two FAdV serotypes.

Abstract
Egg drop syndrome virus (EDSV) strain FJ12025 was isolated from a 9-day-old Muscovy duckling. The results of the sequence showed that the genome of strain FJ12025 is 33,213 bp in length, with a G+C content of 43.03%. When comparing the genome sequence of strain FJ12025 to that of laying duck original strain AV-127, we found 50 single-nucleotide polymorphisms (SNPs) between the two viral genome sequences. A genomic sequence comparison of FJ12025 and AV-127 will help to understand the phenotypic differences between the two viruses.

Abstract
Egg drop syndrome virus (EDSV) is an important pathogen of poultry that decreases egg production in chickens and causes respiratory disease in goslings. In 2011, we obtained serum samples from 139 domestic Pekin ducks, 416 one-day-old Pekin ducklings, and 75 wild ducks (67 mallards and 8 pintails) to survey their exposure to EDSV. A total of 123 of 139 sera (88.5%) from Pekin ducks, 396 of the ducklings (95.2%), and 16 of 67 mallards (23.9%) were positive. Field cases of EDSV in wild and domestic ducks were investigated. Six cases from domestic Pekin ducks were identified by PCR detection and were used for virus isolation and molecular analysis. Phylogenetic analyses of the partial hexon and full fiber genes showed that the D11-JW-012 and D11-JW-017 strains among 6 isolates belonged to different clusters compared with other known strains including the 127 strain. We assessed cell growth efficiency by hemagglutination (HA) titers and cytopathic effects in duck embryo liver cells and chicken embryo liver (CEL) cells to investigate host adaptation. The D11-JW-017 strain propagated more in chicken embryo liver than the D11-JW-012 strain and the field isolate from chickens. Our results demonstrate the high prevalence of EDSV in wild and domestic ducks in South Korea and provide information on EDSV from ducks that showed variable adaptability in chickens.

Abstract
Five Indian isolates of egg drop syndrome (EDS) 1976 virus and the reference strain 127 were compared by restriction enzyme analysis of viral DNA, and the hexon gene amplified by polymerase chain reaction. Using these techniques, no differences were seen among these viruses. However, partial sequencing of the hexon gene revealed major differences (4.6%) in one of the isolates sequenced, EDS Kerala. Phylogenetic analysis also placed this isolate in a different lineage compared with the other isolates. The need for constant monitoring of the genetic nature of the field isolates of EDS viruses is emphasized.

Abstract
Adenoviruses are frequent infectious agents in different poultry species. The traditional, serological typing of new isolates by virus neutralisation tests is now in transition to be replaced by PCR and sequencing. The first PCRs, recommended for the detection of adenoviruses, had been designed to target the gene of the major capsid protein, the hexon. In birds, members of three different genera of the family Adenoviridae may occur. Accordingly, three specific hexon PCRs had to be elaborated for the detection of adenoviruses in poultry. A significantly more sensitive PCR, targeting the viral DNA-dependent DNA polymerase gene, has been described recently. This method proved to be an efficient alternative for the general detection of adenoviruses irrespective of their genus affiliation. Fowl adenoviruses (FAdVs), isolated from chicken to date, comprise twelve serotypes classified into five virus species (FAdV-A to E). The polymerase gene sequence has been determined yet only from three FAdV types representing three species. In the present work, the panel of polymerase gene sequences was completed with those of the rest of FAdVs. The newly determined sequences will facilitate the identification of new FAdV isolates as an existing species or as a putative new FAdV. Once the polymerase sequence is known, more specific PCRs for the amplification of the hexon and other genes can be designed and performed according to the preliminary species classification.

Abstract
Currently, the family Adenoviridae contains five genera, out of which Siadenovirus is one of the two least densely populated ones. A new member representing a new species in this genus has been detected in various birds of prey. The virus, named raptor adenovirus 1 (RAdV-1), could not be isolated, probably because no appropriate permissive cell-line was available. Partial genomic sequences, obtained by PCR and suggesting that the virus is a new siadenovirus species, have been published earlier. In the present paper, determination and analysis of the complete RAdV-1 genome are reported. This is the first complete genome sequence acquired from a non-isolated adenovirus (AdV). The sole source was a mixture of the internal organs of the diseased and dead birds. Until now, the genomic organization considered characteristic to siadenoviruses had been deduced from the detailed study of only two virus species, one of which originated from birds and the other from a frog. The present analysis of RAdV-1 confirmed the genus-specific genetic content and genomic features of siadenoviruses, and a putative novel gene was found as well. In general, AdVs and most of the AdV genera are thought to be strictly host specific. In the genus Siadenovirus, however, two virus species of rather divergent (avian and amphibian) host origin were present when the genus was found. Although by now the greatest number of known siadenoviruses infect birds, the original hosts of the genus remain unknown.

Abstract
In this study we determined and analyzed the complete nucleotide sequence of the genome of a fowl adenovirus serotype 8 (FAdV-8) isolate and examined its pathogenicity in chickens. The full genome of FAdV-8 was 44,055 nucleotides in length with a similar organization to that of FAdV-1 and FAdV-9 genomes. No regions homologous to early regions E1, E3 and E4 of mastadenoviruses were recognized. Along with FAdV-9, FAdV-8 has only one fiber gene and with regard to sequence composition and genome organization, FAdV-8 is closer to FAdV-9 than to FAdV-1. Moreover, our findings suggest that FAdV-1 of species Fowl adenovirus A as the current type species despite its historical priority is not representative of the genus Aviadenovirus, and that FAdV-8 or FAdV-9 in species Fowl adenovirus E and Fowl adenovirus D, respectively, would be more suitable for that designation. Additionally, pathogenicity of FAdV-8 was studied in specific pathogen free chickens following oral and intramuscular inoculations. Despite lack of clinical signs and pathological changes virus was found in tissues and cloacal swabs of all birds with the highest viral copy numbers present in the cecal tonsils. The highest virus titers in the feces for orally and intramuscularly inoculated chickens were recorded at days 10 and 3 post-infection, respectively.

Abstract
A total of 44 fowl adenovirus (FAdV) samples from 6 European countries, Pakistan, India, Kuwait, Mexico, Peru and Ecuador were used in this study and the phylogenetic analyses based on the loop 1 (L1) region of hexon gene were performed. For comparison, available hexon sequences of representatives of different FAdV species were also used. At least 12 genotypes within the five FAdV species (A-E) were revealed and the existence of these genotypes was supported by high bootstrap values. Furthermore, three primer pairs binding to the conserved pedestal regions (HexL1s/HexL1as and HexA/HexB) and pedestal (P1) region and loop 2 (L2) region (HexF1/HexR1) of the FAdV hexon gene were used for high-resolution melting (HRM)-curve analysis and results were compared with those of phylogenetic analyses. HRM-curve analysis based on the HexL1s/HexL1as region grouped all tested field isolates and reference strains into 22 subgroups, consistently with phylogenetic analysis. This method is a rapid and cost-effective alternative to existing serotype identification methods and offers a possibility to classify FAdV isolates more precisely. However, it has limitations such as need for extensive interpretation of results and potential for indeterminate results. Gaining of hexon sequences of further field isolates offers the potential for novel and additional information in analysis of the molecular epidemiology of FAdV.

Abstract
Zoonotic infections constitute a major public health concern. Outbreaks of the SARS (severe acute respiratory syndrome) and avian influenza viruses are but recent examples. Although there are many animal-specific adenoviruses and occasionally they have been noted to infect man, rarely have they been studied as potential zoonotic pathogens. In this study, the authors hypothesized that the hemorrhagic enteritis virus (HEV), an avian adenovirus that causes illness among turkeys, might infect humans. Using an enzyme immunosorbent assay, the authors compared sera from 95 turkey-exposed individuals with sera from 82 nonexposed controls for serologic evidence of infection with HEV. Multivariate modeling revealed no statistical difference in elevated antibody titers against HEV between the two groups. These data do not support the hypothesis that avian adenoviruses cross the species barrier to infect humans.

Abstract
To date, several DNA viral infections have been reported in psittacine birds. Psittacine beak and feather disease (PBFD) is characterized by symmetric feather dystrophy and loss and development of beak deformities. PBFD is caused by beak and feather virus, which belongs to the Circoviridae, and is the most important infection in psittacine birds worldwide. Avian polyomavirus infection causes acute death, abdominal distention, and feather abnormalities. Pacheco's disease (PD), which is caused by psittacid herpesvirus type 1, is an acute lethal disease without a prodrome. Psittacine adenovirus infections are described as having a clinical progression similar to PD. The clinical changes in psittacine poxvirus-infected birds include serious ocular discharge, rhinitis, and conjunctivitis, followed by the appearance of ulcerations on the medial canthi of the eyes. Internal papillomatosis of parrots (IPP) is a tumor disease characterized by progressive development of papillomas in the oral and cloacal mucosa. IPP has been suggested to caused by papillomavirus or herpesvirus. However, information about these diseases is limited. Here we review the etiology, clinical features, pathology, epidemiology, and diagnosis of these DNA viruses.

Abstract
A seemingly novel siadenovirus species was detected by PCR and sequencing in the sample of a great tit (Parus major) found dead in Hungary. Since the genus Siadenovirus has very few known members so far, further study of the virus was intriguing not only from epizootiological but also from taxonomical aspects. The sample, which had been tested in another PCR survey previously, consisted of less than 50 microl of extracted nucleic acid. To ensure sufficient target DNA for an extended study, the viral genome had to be preserved. To this end, the sample was subjected to a novel method of non-specific DNA amplification. Using the amplified DNA as target, different PCR and sequencing strategies were applied with consensus or specific primers for the study of the central genome part of the putative tit adenovirus. The sequence of supposedly one half (13,628 bp) of the genome was determined including eight full genes between the genes of the IVa2 and hexon proteins. The gene content of the viral genome fragment as well as the results of the phylogenetic analyses with different proteins confirmed the discovery of a new species in the genus Siadenovirus. This is the first report on the detection of an adenovirus in great tits. The methods, described in this work, proved suitable for the recovery of nucleic acid samples that contain irreplaceable microbial genomic DNA but are only available in limited quantities.

Abstract
Partial genome characterisation of a novel adenovirus, found recently in organ samples of multiple species of dead birds of prey, was carried out by sequence analysis of PCR-amplified DNA fragments. The virus, named as raptor adenovirus 1 (RAdV-1), has originally been detected by a nested PCR method with consensus primers targeting the adenoviral DNA polymerase gene. Phylogenetic analysis with the deduced amino acid sequence of the small PCR product has implied a new siadenovirus type present in the samples. Since virus isolation attempts remained unsuccessful, further characterisation of this putative novel siadenovirus was carried out with the use of PCR on the infected organ samples. The DNA sequence of the central genome part of RAdV-1, encompassing nine full (pTP, 52K, pIIIa, III, pVII, pX, pVI, hexon, protease) and two partial (DNA polymerase and DBP) genes and exceeding 12 kb pairs in size, was determined. Phylogenetic tree reconstructions, based on several genes, unambiguously confirmed the preliminary classification of RAdV-1 as a new species within the genus Siadenovirus. Further study of RAdV-1 is of interest since it represents a rare adenovirus genus of yet undetermined host origin.

Abstract
Genome sequencing and analysis of snake adenovirus type 1 (SnAdV-1), originating from corn snake, were completed. This is the first full genomic sequence of an adenovirus from reptilian hosts. The presence of characteristic genus-common genes and transcription units, showed that SnAdV-1 shares similar genome organisation with members of the recently established genus Atadenovirus. Three novel open reading frames of yet unknown functions were found. One of these seemed to be related to a putative gene, the so-called 105R that has recently been described from the genome of the tree shrew adenovirus. The other two putative genes were found to be unique for SnAdV-1. On phylogenetic trees, SnAdV-1 clustered within the atadenovirus clade. Thereby the hypothesis on the reptilian origin of atadenoviruses was further strengthened. Interestingly, however, one of the most striking features of atadenoviruses, namely the base content heavily biased towards A+T, is not characteristic for SnAdV-1 having a genome of balanced composition with a G+C value of 50.21%.

Abstract
Canine adenovirus type 2 (CAV2) has become an attractive vector for gene therapy because of its non-pathogenicity and the lack of pre-existing neutralizing antibodies against this virus in the human population. Additionally, this vector has been proposed as a conditionally replicative adenovirus agent under the control of an osteocalcin promoter for evaluation in a syngeneic, immunocompetent canine model with spontaneous osteosarcoma. In this study, a CAV2 vector labelled with the fluorescent capsid fusion protein IX-enhanced green fluorescent protein (pIX-EGFP) was developed. Expression of the fluorescent fusion-protein label in infected cells with proper nuclear localization, and incorporation into virions, could be detected. The labelled virions could be visualized by fluorescence microscopy; this was applicable to the tracking of CAV2 infection, as well as localizing the distribution of the vector in tissues. Expression of pIX-EGFP could be exploited to detect the replication and spread of CAV2. These results indicate that pIX can serve as a platform for incorporation of heterologous proteins in the context of a canine adenovirus xenotype. It is believed that capsid-labelled CAV2 has utility for vector-development studies and for monitoring CAV2-based oncolytic adenovirus replication.

Abstract
Hemorrhagic enteritis virus (HEV) is an adenovirus that infects turkeys and causes immunosuppression and mortality. The virus used for the inactivated vaccine is extracted from spleens of infected turkeys, since its propagation in tissue cultures or embryonated eggs is unsuitable for mass production. The aim of this study was to develop a subunit vaccine based on a capsid protein of the virus. The knob protein, together with an adjacent part of the shaft domain pertaining to the fiber protein of HEV, was expressed in Escherichia coli and tested as a vaccine. Vaccination with this recombinant protein conferred protection against challenge in controlled and in floor-pen experiments. This finding suggests that the knob protein may be used as safe and efficient vaccine against hemorrhagic enteritis of turkeys. The possibility that the knob proteins of other adenoviruses may be protective and serve as vaccine is also discussed.

Abstract
Adenovirus infections in psittacine birds have been well known. Most of these infections were caused by fowl adenoviruses (FAdV). In this study, liver samples showing typical histological signs of an adenovirus infection were collected from Poicephalus spp. with acute disease. A PCR amplifying the variable loop 1 region of the hexon gene was developed using primers located in two conserved pedestal regions. A PCR product of approximately 590 bp in size was amplified and sequenced. The sequence obtained grouped outside of the FAdV reference strains of the 12 serotypes as well as egg drop syndrome virus and turkey adenovirus 3 indicating that a new avian adenovirus was detected. In comparison to the FAdV reference strains, the percentage of identical nucleotides ranged between 60.3 and 67.0 and that of identical amino acids (aa) between 51.3 and 61.0. Furthermore, 37 unique aa exchanges were observed; out of these, 27 are located in the 4 hypervariable regions of loop 1, which encode the serotype-specific epitopes. The g/c content, the isoelectric point and the charge of the amplified fragment, however, are in the range as those of group I avian adenoviruses. It was proposed, therefore, to designate this new adenovirus as psittacine adenovirus (PsAdV).

Abstract
The genome of Marek's disease virus (MDV) has been predicted to encode a secreted glycoprotein, vLIP, which bears significant homology to the alpha/beta hydrolase fold of pancreatic lipases. Here it is demonstrated that MDV vLIP mRNA is produced via splicing and that vLIP is a late gene, due to its sensitivity to inhibition of DNA replication. While vLIP was found to conserve several residues essential to hydrolase activity, an unfavorable asparagine substitution is present at the lipase catalytic triad acid position. Consistent with structural predictions, purified recombinant vLIP did not show detectable activity on traditional phospholipid or triacylglyceride substrates. Two different vLIP mutant viruses, one bearing a 173-amino-acid deletion in the lipase homologous domain, the other having an alanine point mutant at the serine nucleophile position, caused a significantly lower incidence of Marek's disease in chickens and resulted in enhanced survival relative to two independently produced vLIP revertants or parental virus. These data provide the first evidence that vLIP enhances the replication and pathogenic potential of MDV. Furthermore, while vLIP may not serve as a traditional lipase enzyme, the data indicate that the serine nucleophile position is nonetheless essential in vivo for the viral functions of vLIP. Therefore, it is suggested that this particular example of lipase homology may represent the repurposing of an alpha/beta hydrolase fold toward a nonenzymatic role, possibly in lipid bonding.
