Postcranial pneumaticity and bone structure in two clades of neognath birds.
This study examined the influence of skeletal pneumatization on bone structural parameters in a sample of two size- and foraging-style diverse (e.g., subsurface diving vs. soaring specialists) clades of neognath birds (charadriiforms and pelecaniforms). Cortical bone thickness and trabecular bone volume fraction were assessed in one cervical and one thoracic vertebra in each of three pelecaniform and four charadriiform species. Results for pelecaniforms indicate that specialized subsurface dive foragers (e.g., the apneumatic anhinga) have thicker cortical bone and a higher trabecular bone volume fraction than their non-div...

Glycoprotein C plays a role in the adsorption of duck enteritis virus to chicken embryo fibroblasts cells and in infectivity.
In this study, we showed that gC expressed in vitro could bind to chicken embryo fibroblasts (CEF) cells and inhibit the adsorption of duck enteritis virus (DEV) onto CEF cells effectively and antiserum directed against gC inhibited the infection of DEV. Furthermore, it was confirmed that gC protein expressed in baculovirus system did not bind to heparin-Sepharose beads and virus binding to cells were independent of heparin sulfate proteoglycans on the surface of cells. Therefore, gC contributes to adsorption and infection of DEV. PMID: 23454009 [PubMed - in process] (Source: Virus Research)

Production of avian influenza virus vaccine using primary cell cultures generated from host organs.
Abstract The global availability of a therapeutically effective influenza virus vaccine during a pandemic remains a major challenge for the biopharmaceutical industry. Long production time, coupled with decreased supply of embryonated chicken eggs (ECE), significantly affects the conventional vaccine production. Transformed cell lines have attained regulatory approvals for vaccine production. Based on the fact that the avian influenza virus would infect the cells derived from its natural host, the viral growth characteristics were studied on chicken embryo-derived primary cell cultures. The viral propagation was de...

The effects of body temperature and mass on the postprandial metabolic responses of the African egg-eating snakes Dasypeltis scabra and Dasypeltis inornata.
Abstract African egg-eating snakes (Dasypeltis) feed only on freshly laid bird eggs which they perforate within their esophagus before swallowing the liquid contents and regurgitating the empty shell. Compared to a snake's typical intact meal, the liquid diet of Dasypeltis would expectedly generate a more moderate postprandial metabolic response and specific dynamic action (SDA). Free-ranging Dasypeltis feed over a range of ambient temperatures and thereby experience predicted temperature-dependent shifts in the duration and magnitude of their postprandial metabolic response. Such shifts would undoubtedly be shared...

Detection of Candida species resistant to azoles in the microbiota of rheas (Rhea americana): possible implications for human and animal health.
Abstract There is growing interest in breeding rheas (Rhea americana) in Brazil. However, there are no data on the yeast microbiota of the gastrointestinal tract of this avian species, and the phenotypic characteristics of these yeasts are not known. Therefore, the aim of this work was to isolate Candida species from the digestive tract of rheas and to evaluate the in vitro antifungal susceptibility and secretion of phospholipases of the recovered isolates. For this purpose, 58 rheas from breeding operations in the cities of Fortaleza and Mossoró, north-eastern Brazil, were used. Samples were gathered from the oro...

Qualitative dynamics of lowly- and highly-pathogenic avian influenza strains.
Abstract A new deterministic model for the transmission dynamics of the lowly- and highly-pathogenic avian influenza (LPAI and HPAI) strains is designed and rigorously analyzed. The model exhibits the phenomenon of backward bifurcation, where a stable disease-free equilibrium co-exists with a stable endemic equilibrium whenever the associated reproduction number is less than unity. It is shown that the re-infection of birds infected with the LPAI strain causes the backward bifurcation phenomenon. In the absence of such re-infection, the disease-free equilibrium of the model is globally-asymptotically stable when th...

Ferrets, pigs susceptible to H7N9 avian influenza virus
(NIH/National Institute of Allergy and Infectious Diseases) Chinese and US scientists have used a virus isolated from a person who died from H7N9 avian influenza infection to determine whether the virus could infect and be transmitted between ferrets. Ferrets are often used as a mammalian model in influenza research, and efficient transmission of influenza virus between ferrets can provide clues as to how well the same process might occur in people.

Evolution of parental incubation behaviour in dinosaurs cannot be inferred from clutch mass in birds.
Abstract A recent study proposed that incubation behaviour (i.e. type of parental care) in theropod dinosaurs can be inferred from an allometric analysis of clutch volume in extant birds. However, the study in question failed to account for factors known to affect egg and clutch size in living bird species. A new scaling analysis of avian clutch mass demonstrates that type of parental care cannot be distinguished by conventional allometry because of the confounding effects of phylogeny and hatchling maturity. Precociality of young but not paternal care in the theropod ancestors of birds is consistent with the avail...

Migration confers survival benefits against avian predators for partially migratory freshwater fish.
Abstract The importance of predation risk in shaping patterns of animal migration is not well studied, mostly owing to difficulties in accurately quantifying predation risk for migratory versus resident individuals. Here, we present data from an extensive field study, which shows that migration in a freshwater fish (roach, Rutilus rutilus) that commonly migrates from lakes to streams during winter confers a significant survival benefit with respect to bird (cormorant, Phalacrocorax carbo spp.) predation. We tagged over 2000 individual fish in two Scandinavian lakes over 4 years and monitored migratory behaviour usi...

Species differences in the neuromuscular activity of post-synaptic neurotoxins from two Australian black snakes (Pseudechis porphyriacus and Pseudechis colletti).
Abstract Bites by Australian black snakes (Pseudechis spp.) do not cause neurotoxicity in human envenoming. This is unusual as in vitro neurotoxicity has been reported for all Pseudechis spp. venoms. The present study aimed to identify, isolate and characterise neurotoxins from the venoms of Pseudechis porphyriacus and Pseudechis colletti to elucidate the reason for the lack of neurotoxicity in humans. α-Elapitoxin-Ppr1 and α-elapitoxin-Pc1 were isolated from P. porphyriacus and P. colletti, respectively, using reverse-phase high performance liquid chromatography.

Separating the recent from the ancient past | Dr Dave Hone
The ever-changing landscape can cause some confusion when organic remains of different eras come togetherIt is not uncommon to come across claims of fossils being found in layers where we would not expect them to be, with combinations of animals from different geological eras coming together. A foundation of palaeontology is of course that most groups of organisms tend to come and go – they wax and wane and eventually most (or all) members of a group will become extinct. Thus while mammals lived alongside non-avian dinosaurs, it's only when the latter became extinct that they really expanded and dominated. So we would no...

The prospects and challenges of universal vaccines for influenza.
Abstract Vaccination is the most effective way to reduce the impact of epidemic as well as pandemic influenza. However, the licensed inactivated influenza vaccine induces strain-specific immunity and must be updated annually. When novel viruses appear, matched vaccines are not likely to be available in time for the first wave of a pandemic. Yet, the enormous diversity of influenza A viruses in nature makes it impossible to predict which subtype or strain will cause the next pandemic. Several recent scientific advances have generated renewed enthusiasm and hope for universal vaccines that will induce broad protectio...
