Avian immunosenescence [PDF]

AGE, 2005
Immunosenescence, the aging of the immune system, is well studied in humans. Mammalian immune systems become less capable of fighting pathogens and individuals become more susceptible to infection and cancer in their elder years. Little is currently published on avian immunosenescence even though avian immune function has been well characterized and ...

Immune Responses to Avian Influenza Viruses

Journal of Immunology, 2019
Avian influenza A viruses (IAVs) naturally infect different avian species, and aquatic birds are their natural reservoir. Sporadically, avian IAVs can be transmitted to humans, and some, such as H5N1 and H7N9 viruses, cause severe disease in humans ...

Efficacy and Underpinnings of the Effigy in Wildlife Management

Animals
Displaying representations or actual individuals of the same or similar species can have a congregating or deterring effect on animals. An effigy, an animal or animal representation in a moribund state, is a tool aimed at deterring target animals in ...

One-way trip: Influenza virus' adaptation to gallinaceous poultry may limit its pandemic potential [PDF]

, 2014
We hypothesise that some influenza virus adaptations to poultry may explain why the barrier for human-to-human transmission is not easily overcome once the virus has crossed from wild birds to chickens.

Avian Interferons and Their Antiviral Effectors

Frontiers in Immunology, 2017
Interferon (IFN) responses, mediated by a myriad of IFN-stimulated genes (ISGs), are the most profound innate immune responses against viruses. Cumulatively, these IFN effectors establish a multilayered antiviral state to safeguard the host against ...

Avian malaria co-infections confound infectivity and vector competence assays of Plasmodium homopolare. [PDF]

, 2018
Currently, there are very few studies of avian malaria that investigate relationships among the host-vector-parasite triad concomitantly. In the current study, we experimentally measured the vector competence of several Culex mosquitoes for a newly ...

Avian acrobatics [PDF]

Proceedings of the National Academy of Sciences, 2013
As flying vertebrates go, hummingbirds are veritable humdingers. Featherweight members of the vertebrate subphylum, some species of hummingbirds can thrive at heights of 5,000 meters above sea level, hovering in thin air at high-altitude habitats, which pose formidable challenges to certain forms of flight. With rising altitude, the drop in atmospheric

Rapid 18F-FDG Uptake in Brain of Awake, Behaving Rat and Anesthetized Chicken has Implications for Behavioral PET Studies in Species With High Metabolisms

Frontiers in Behavioral Neuroscience, 2018
Brain-behavior studies using 18F-FDG PET aim to reveal brain regions that become active during behavior. In standard protocols, 18F-FDG is injected, the behavior is executed during 30–60 min of tracer uptake, and then the animal is anesthetized and ...

Human infections associated with wild birds. [PDF]

, 2008
IntroductionWild birds and especially migratory species can become long-distance vectors for a wide range of microorganisms. The objective of the current paper is to summarize available literature on pathogens causing human disease that have been ...

Coronaviruses in Avian Species – Review with Focus on Epidemiology and Diagnosis in Wild Birds

Journal of Veterinary Research, 2018
Coronaviruses (CoVs) are a large group of enveloped viruses with a single-strand RNA genome, which continuously circulate in mammals and birds and pose a threat to livestock, companion animals, and humans.
