The PHA test reflects acquired T-cell mediated immunocompetence in birds. [PDF]

open access: yesPLoS ONE, 2008
cological immunology requires techniques to reliably measure immunocompetence in wild vertebrates. The PHA-skin test, involving subcutaneous injection of a mitogen (phytohemagglutinin, PHA) and measurement of subsequent swelling as a surrogate of T-cell ...

Supplementation of ginger root extract into broiler chicken diet: effects on growth performance and immunocompetence

open access: yesPoultry Science, 2023
: Ginger contains bioactive compounds that possess anti-inflammatory and antimicrobial properties. In this study, 432-day-old Ross 708 broiler male chicks were randomly allocated to 6 dietary treatments to investigate the effect of ginger root extract ...

Laying performance, immune response and antioxidant properties of hens segregating for naked neck and frizzle genes under low ambient temperature

open access: yesCzech Journal of Animal Science, 2019
Major genes could be introgressed into laying hens to attenuate heat stress. However, under cold and/or moderate ambient temperature, these genes might possess different behaviour.

Experimental evolution reveals sex‐specific dominance for surviving bacterial infection in laboratory populations of Drosophila melanogaster

open access: yesEvolution Letters, 2021
Males and females are subjected to distinct kinds of selection pressures, often leading to the evolution of sex‐specific genetic architecture, an example being sex‐specific dominance.

Torque Teno Virus as a Potential Biomarker for Complications and Survival After Allogeneic Hematopoietic Stem Cell Transplantation

open access: yesFrontiers in Immunology, 2020
Impaired immune reconstitution after allogeneic hematopoietic stem cell transplantation (HSCT) contributes to increased risk of cancer relapse and infection resulting in significant morbidity and mortality.

Influence of Feeding Omega-3 Polyunsaturated Fatty Acids to Broiler Breeders on Indices of Immunocompetence, Gastrointestinal, and Skeletal Development in Broiler Chickens

open access: yesFrontiers in Veterinary Science, 2021
Modern broiler chickens are associated with rapid growth rates and superior feed efficiency. However, they are also susceptible to physiological and metabolic disorders (e.g., skin lesions, lameness, sudden death, enteric diseases, myopathies) that exert

Immunoglobulin G4-Related Disease Involving the Pterygopalatine Fossa, Mimicking Invasive Aspergillosis: A Case Report and Literature Review

open access: yes대한영상의학회지, 2021
We report a case of Immunoglobulin G4 (IgG4) related disease involving the pterygoplataine fossa. A 83-year-old male presented with left ocular pain and visual disturbance. CT showed an isodense soft tissue lesion in the left pterygopalatine fossa with

Ecologic Immunology of Avian Influenza (H5N1) in Migratory Birds

open access: yesEmerging Infectious Diseases, 2007
The claim that migratory birds are responsible for the long-distance spread of highly pathogenic avian influenza viruses of subtype H5N1 rests on the assumption that infected wild birds can remain asymptomatic and migrate long distances unhampered.

Helicobacter cinaedi Hepatic Cyst Infection with Bacteremia

open access: yesEmerging Infectious Diseases, 2019
Helicobacter cinaedi is an enterohepatic bacillus that causes infections of various manifestations. We report a novel case of hepatic cyst infection with bacteremia caused by H. cinaedi in an immunocompetent woman in Japan.

Iron, copper and immunocompetence [PDF]

open access: yesBritish Journal of Nutrition, 2007
Microminerals including copper and iron are essential to immunity and health in human beings. The development of powerful tools in analytical cell biology and molecular genetics has facilitated efforts to identify specific cellular and molecular functions of trace elements in the maturation, activation and functions of host defence mechanisms. Selected
