Identification and analysis of a new hepadnavirus in white storks. (1/18)

We identified, cloned, and functionally characterized a new avian hepadnavirus infecting storks (STHBV). STHBV has the largest DNA genome of all avian hepadnaviruses and, based on sequence and phylogenetic analysis, is most closely related to, but distinct from, heron hepatitis B virus (HHBV). Unique for STHBV among the other avian hepadnaviruses is a potential HNF1 binding site in the preS promoter. In common only with HHBV, STHBV has a myristylation signal on the S and not the preS protein, two C terminally located glycosylation sites on the precore/core proteins and lacks the phosphorylation site essential for the transcriptional transactivation activity of duck-HBV preS protein. The cloned STHBV genomes were competent in gene expression, replication, and viral particle secretion. STHBV infected primary duck hepatocytes very inefficiently suggesting a restricted host range, similar to other hepadnaviruses. This discovery of stork infections unravels novel evolutionary aspects of hepadnaviruses and provides new opportunities for hepadnavirus research.  (+info)

cis-Acting sequences 5E, M, and 3E interact to contribute to primer translocation and circularization during reverse transcription of avian hepadnavirus DNA. (2/18)

Hepadnaviral reverse transcription requires template switches for the genesis of relaxed circular (RC) DNA, the major genomic form in virions. Two template switches, primer translocation and circularization, are required during the synthesis of the second, or plus, strand of DNA. Studies of duck hepatitis B virus (DHBV) indicate that in addition to the requirement for repeated sequences at the donor and acceptor sites, template switching requires at least three other cis-acting sequences, 5E, M, and 3E. In this study we analyzed a series of variant heron hepatitis B viruses (HHBV) in which the regions of the genome that would be expected to contain 5E, M, and 3E were replaced with DHBV sequence. We found that all single and double chimeras were partially defective in the synthesis of RC DNA. In contrast, the triple chimera was able to synthesize RC DNA at a level comparable to that of unchanged HHBV. These results indicate that the three cis-acting sequences, 5E, M, and 3E, need to be compatible to contribute to RC DNA synthesis, suggesting that these sequences interact during plus-strand synthesis. Second, we found that the defect in RC DNA synthesis for several of the single and double chimeric viruses resulted from a partial defect in primer translocation/utilization and a partial defect in circularization. These findings indicate that the processes of primer translocation and circularization share a mechanism during which 5E, M, and 3E interact.  (+info)

Identification and characterization of a novel replicative intermediate of heron hepatitis B virus. (3/18)

We have identified and characterized a novel intracellular DNA replicative intermediate that is synthesized by heron hepatitis B virus (HHBV) and not by other avian hepadnaviruses. The new DNA form is synthesized in all host cells tested. The HHBV nucleic acid template, and not HHBV proteins, is responsible for the formation of the new form. The new form is comprised of a full-length minus-strand DNA and an incomplete plus-strand DNA whose 5' ends are mapped to DR2, predominantly. The 3' ends of its plus-strand are located between nucleotides 946 and 1046. Genetic analysis indicates that the sequences responsible for the formation of the new form lie between nucleotides 910 and 1364. The endogenous polymerase activity of capsids isolated from cells converted the new form into RC DNA. Intracellular capsids containing the new form are secreted inefficiently as virions, in comparison to RC- and DL DNA-containing capsids. Our analysis suggests that the new form is an incomplete RC DNA molecule that is due to a specific block or pause in the synthesis of plus-strand DNA. Our analysis also suggests that capsids become competent for efficient secretion sometime after the synthesis of 1500 nucleotides of plus-strand DNA.  (+info)

Avian and Mammalian hepadnaviruses have distinct transcription factor requirements for viral replication. (4/18)

Hepadnavirus replication occurs in hepatocytes in vivo and in hepatoma cell lines in cell culture. Hepatitis B virus (HBV) replication can occur in nonhepatoma cells when pregenomic RNA synthesis from viral DNA is activated by the expression of the nuclear hormone receptors hepatocyte nuclear factor 4 (HNF4) and the retinoid X receptor alpha (RXR alpha) plus peroxisome proliferator-activated receptor alpha (PPAR alpha) heterodimer. Nuclear hormone receptor-dependent HBV replication is inhibited by hepatocyte nuclear factor 3 (HNF3). In contrast, HNF3 and HNF4 support duck hepatitis B virus (DHBV) replication in nonhepatoma cells, whereas the RXR alpha-PPAR alpha heterodimer inhibits HNF4-dependent DHBV replication. HNF3 and HNF4 synergistically activate DHBV pregenomic RNA synthesis and viral replication. The conditions that support HBV or DHBV replication in nonhepatoma cells are not able to support woodchuck hepatitis virus replication. These observations indicate that avian and mammalian hepadnaviruses have distinct transcription factor requirements for viral replication.  (+info)

Characterization of the cis-acting contributions to avian hepadnavirus RNA encapsidation. (5/18)

Previous analysis of duck hepatitis B virus (DHBV) indicated the presence of at least two cis-acting sequences required for efficient encapsidation of its pregenomic RNA (pgRNA), epsilon and region II. epsilon, an RNA stem-loop near the 5' end of the pgRNA, has been characterized in detail, while region II, located in the middle of the pgRNA, is not as well defined. Our initial aim was to identify the sequence important for the function of region II in DHBV. We scanned region II and the surrounding sequence by using a quantitative encapsidation assay. We found that the sequence between nucleotides (nt) 438 and 720 contributed to efficient pgRNA encapsidation, while the sequence between nt 538 and 610 made the largest contribution to encapsidation. Additionally, deletions between the two encapsidation sequences, epsilon and region II, had variable effects on encapsidation, while substitutions of heterologous sequence between epsilon and region II disrupted the ability of the pgRNA to be encapsidated efficiently. Overall, these data indicate that the intervening sequences between epsilon and region II play a role in encapsidation. We also analyzed heron hepatitis B virus (HHBV) for the presence of region II and found features similar to DHBV: a broad region necessary for efficient encapsidation that contained a critical region II sequence. Furthermore, we analyzed variants of DHBV that were substituted with HHBV sequence over region II and found that the chimeras were not fully functional for RNA encapsidation. These results indicate that sequences within region II may need to be compatible with other viral components in order to function in pgRNA encapsidation.  (+info)

Chimeras of duck and heron hepatitis B viruses provide evidence for functional interactions between viral components of pregenomic RNA encapsidation. (6/18)

Packaging of hepadnavirus pregenomic RNA (pgRNA) into capsids, or encapsidation, requires several viral components. The viral polymerase (P) and the capsid subunit (C) are necessary for pgRNA encapsidation. Previous studies of duck hepatitis B virus (DHBV) indicated that two cis-acting sequences on pgRNA are required for encapsidation: epsilon, which is near the 5' end of pgRNA, and region II, located near the middle of pgRNA. Later studies suggested that the intervening sequence between these two elements may also make a contribution. It has been demonstrated for DHBV that epsilon interacts with P to facilitate encapsidation, but it is not known how other cis-acting sequences contribute to encapsidation. We analyzed chimeras of DHBV and a related virus, heron hepatitis B virus (HHBV), to gain insight into the interactions between the various viral components during pgRNA encapsidation. We learned that having epsilon and P derived from the same virus was not sufficient for high levels of encapsidation, implying that other viral interactions contribute to encapsidation. Chimeric analysis showed that a large sequence containing region II may interact with P and/or C for efficient encapsidation. Further analysis demonstrated that possibly an RNA-RNA interaction between the intervening sequence and region II facilitates pgRNA encapsidation. Together, these results identify functional interactions among various viral components that contribute to pgRNA encapsidation.  (+info)

Identification and characterization of avihepadnaviruses isolated from exotic anseriformes maintained in captivity. (7/18)

Five new hepadnaviruses were cloned from exotic ducks and geese, including the Chiloe wigeon, mandarin duck, puna teal, Orinoco sheldgoose, and ashy-headed sheldgoose. Sequence comparisons revealed that all but the mandarin duck viruses were closely related to existing isolates of duck hepatitis B virus (DHBV), while mandarin duck virus clones were closely related to Ross goose hepatitis B virus. Nonetheless, the S protein, core protein, and functional domains of the Pol protein were highly conserved in all of the new isolates. The Chiloe wigeon and puna teal hepatitis B viruses, the two new isolates most closely related to DHBV, also lacked an AUG start codon at the beginning of their X open reading frame (ORF). But as previously reported for the heron, Ross goose, and stork hepatitis B viruses, an AUG codon was found near the beginning of the X ORF of the mandarin duck, Orinoco, and ashy-headed sheldgoose viruses. In all of the new isolates, the X ORF ended with a stop codon at the same position. All of the cloned viruses replicated when transfected into the LMH line of chicken hepatoma cells. Significant differences between the new isolates and between these and previously reported isolates were detected in the pre-S domain of the viral envelope protein, which is believed to determine viral host range. Despite this, all of the new isolates were infectious for primary cultures of Pekin duck hepatocytes, and infectivity in young Pekin ducks was demonstrated for all but the ashy-headed sheldgoose isolate.  (+info)

Evidence from nature: interspecies spread of heron hepatitis B viruses. (8/18)

Heron hepatitis B viruses (HHBVs) in three subspecies of free-living great blue herons (Ardea herodias) from Florida, USA, were identified and characterized. Eight of 13 samples were positive in all assays used, whereas sera from egrets, which are also members of the family Ardeidae, were negative in the same assays. Comparative phylogenetic analysis of viral DNA sequences from the preS/S region of previously reported and novel HHBV strains isolated from captive grey herons (Germany) and free-ranging great blue herons (USA), respectively, revealed a strong conservation (95 % sequence similarity) with two separate clusters, implying a common ancestor of all strains. Our data demonstrate for the first time that different subspecies of herons are infected by HHBV and that these infections exist in non-captive birds. Phylogenetic analysis and the fact that the different heron species are geographically isolated populations suggest that lateral transmission, virus adaptation and environmental factors all play a role in HHBV spreading and evolution.  (+info)

Comparison of DHBV and HHBV.In the 200-nt deletion analyses (Fig. 2 and 4), we scanned 2,536 nt of DHBV pgRNA and 2,466 nt of HHBV pgRNA. Comparison of the histograms in Fig. 2B and 4B indicates a significant difference between DHBV and HHBV. For HHBV, removal of sequences over a cumulative span of 1,822 nt (HΔ3 to HΔ4, 354 nt; HΔ6 to HΔ14, 1,111 nt; HΔ17 to HΔ18, 357 nt) resulted in a reduction in minus-strand DNA to less than or equal to 42% of the WT reference level. This sensitivity of HHBV is not a complete intolerance for a smaller-than-WT-size pgRNA, because the variant HΔ5 (Fig. 4), which has 200 nt removed, synthesizes minus-strand DNA as well as the WT reference. In contrast, only one DHBV deletion (DΔ12) was below 48%. These results suggest that HHBV has more cis-acting requirements for synthesis of minus-strand DNA than DHBV. This interpretation is reinforced upon consideration of the variants DHBVLacZ and HHBVLacZ (Fig. 6), in which the analogous ∼750-nt segments of the ...
Students and teachers from schools across the state played an important role in the field work leading up to the tagging of the five herons. The students and teachers set and checked minnow traps, identified and measured the baitfish caught, and placed the baitfish into a bait bin in order to get a great blue heron to regularly feed from it. They also used game cameras to watch the bait bins when they were not there themselves. After a heron was accustomed to feeding from the bait bin, MDIFW and researchers Dr. John Brzorad (Lenoir-Rhyne University) and Dr. Alan Maccarone (Friends University) set out an array of modified foothold traps near the bait bin to capture the heron so they could tag it with a GPS transmitter. The use of modified foothold traps has been perfected by Brzorad, and involves watching the set traps from a blind until a heron steps into one of the traps. Once trapped, it is then quickly retrieved by the researchers for processing. The bird is kept calm with a hood over its ...
1. The heron is silence by the frozen pool. The heron is patience. It is the wide-gaping beak, the crane bag spilling letters. The heron is water all together and at one time sky in sequence land: great downbeat of wings and neck outstretched. Too still to see, his shadow a hunter. The heron is a woman. The heron is a coat feathers wrapping skin side warm for the dance, the long dance, the circling dance around and back again: the heron is the long gyre north to south along the rivers path; This heron goes.

The diet of the little blue heron primarily consists of fish, insects, shrimp, and amphibians. Little blue herons feed alone, usually along freshwater systems and on floating vegetation. The little blue heron nests in colonies, often with other species of long-legged waders. Nests of sticks are placed in trees and shrubs on islands, thickets near water, or emergent vegetation over water. Little blue herons will lay three to five blue-green eggs that hatch in 20 to 24 days. The young are able to leave the nest and fly (fledge) at 28 days of age.. ...

The yellow-crowned night heron typically has one brood per year. It will try and replace a brood completely lost if it is not too late into the breeding season, but not a partially lost brood. The female lays two to six eggs, depending on the conditions, especially the temperature. The eggs are oval and smooth, with a pale green-blue color. Both parents start guarding the nest as soon as the first egg is laid, and they both incubate the clutch in turn. 24-29 days later, the young hatch, vulnerable and entirely dependent on their parents. They look nothing like the adults with their white-grey short, soft feathers, their wide blue eye-ring and their yellow bill. During the first two weeks, both adults brood the young.

p,In order to ascertain whether black-crowned night herons (BCNH), white heron (Plumed Egrets (PE)) and domestic fowls are infected by JE virus and they serve as infection source ofJE, hemoagglutination inhibiting antibody and its 2·ME sensitive antibody in the sera of these birds were determined. Physico-chemical nature of fowls antibody of JE produced by natural infection and their maternal antibody in the sera of chicks were examined. The results are briefly summarized as follows. 1) As to the herons captured in Tsudaka Town, two out of six adult night herons and three out of the four chicks showed positive HI reaction. On the other hand, HI reaction in the sera of two adult white herons and three chicks were negative. 2) As to the herons captured in Okayama City, twenty out of thirtytwo adult night herons and seven out of seventy white herons showed positive HI reaction in 1966 around the time when JE was prevalent in Okayama Prefecture. And six out of eleven night herons and one out of ...

This little section of the island was home to a mix of Tricolored Herons, Little Blue Herons, Cattle Egrets, and of course, the ever-present Ibis. I wish I had written down a few more notes about this part of the island because Im already starting to forget the little details, but I do remember one thing. With the click of that last photo, I backed right into a plant with lots of thorns -- small little razor-sharp thorns that ripped the skin as I tried to pull away and then stayed in the skin until I pulled them out. And…boy, oh boy did it bleed! Twenty-seven in all, at least they came out easily and didnt hurt that much, but they left a big stinging sensation I didnt like one bit. Theres nothing like seeing blood running down your leg to make you feel like a real birder. I hate to say it, but I kind of dug it, because it made me feel tough…like I was out in the wilds on my own surviving with just a compass and a camera. I had lens tissues in my little pack and after pulling out the ...
DISCUSSION. Range expansion. Although Gianuca et al. (2008) presented evidence of a southward range expansion of the Little Blue Heron, the breeding of the species within the Patos Lagoon estuary had not been confirmed so far. Thus, this study confirms expansion of the breeding range of this heron 400 km south of the limit of Neotropical mangroves (Cintrón-Molero & Schaeffer-Novelli, 1992) and 850 km south of the nearest known breeding sites, located at the Santos-Cubatão mangroves (Olmos & Silva e Silva, 2002).. Temperature is one of the main limiting factors of the large-scale geographical distribution of birds, and low winter temperatures determine the distribution boundaries of several species at higher latitudes (Root, 1988a,b; Matthews et al., 2004). Increase in temperature due to climate changes is primarily responsible for recent geographic expansion of birds in Africa, Europe and North America (Thomas & Lennon, 1999; MacCarty, 2001; Crick, 2004; Parmesan, 2006). According to data from ...
