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 ...

Immune challenge affects reproductive behaviour in the guppy (Poecilia reticulata)

open access: yesRoyal Society Open Science, 2023
Immunocompetence and reproduction are among the most important determinants of fitness. However, energetic and metabolic constraints create conflict between these two life-history traits.

Growth and response to Escherichia coli lipopolysaccharide challenge in Lohmann LSL-Lite pullets when fed a source of omega-3 fatty acids and yeast bioactives from hatch through to 16 wk of age

open access: yesPoultry Science, 2023
: Growth and response to Escherichia coli lipopolysaccharide (LPS) challenge in Lohmann LSL-Lite pullets when fed a source of omega-3 fatty acids (n-3 FA) and yeast bioactives (YB) from hatch through to 16 wk of age (woa) were investigated.

Allergy to Fungi in Veterinary Medicine: Alternaria, Dermatophytes and Malassezia Pay the Bill!

open access: yesJournal of Fungi, 2022
The fungal kingdom comprises ubiquitous forms of life with 1.5 billion years, mostly phytopathogenic and commensals for humans and animals. However, in the presence of immune disorders, fungi may cause disease by intoxicating, infecting or sensitizing ...

Risk factors for respiratory illness in a community of wild chimpanzees (Pan troglodytes schweinfurthii) [PDF]

open access: yesRoyal Society Open Science, 2018
Respiratory illnesses have caused significant mortality in African great ape populations. While much effort has been given to identifying the responsible pathogens, little is known about the factors that influence disease transmission or individual ...

Comparison of complement system activity amongst wild and domestic animals

open access: yesActa Herpetologica, 2020
Multiple mechanisms have evolved for the defensive recognition of foreign components, such as microorganisms. The majority of immunological studies with vertebrates have been focused on endothermic species, and relatively little attention has been ...

Torque Teno Virus Viral Load as a Marker of Immune Function in Allogeneic Haematopoietic Stem Cell Transplantation Recipients

open access: yesViruses, 2020
Torque teno virus (TTV) has been proposed as a surrogate biomarker of T-cell function in allogeneic–haematopoietic–stem-cell transplantation (allo-HSCT). Conflicting data exists regarding the value of TTV to assess the degree of immunosuppression.

Immunocompetence index selection of broiler chicken lines for disease resistance and their impact on survival rate [PDF]

open access: yesVeterinary World, 2013
Aim: This study was aimed to develop the disease resistance broiler chicken lines over two generations (G0 , G1 and G2 ) of selection for immunocompetence (IC) index by targeting all the facets of immune response traits viz., humoral response (HR) to ...

Successful Induction of Specific Immunological Tolerance by Combined Kidney and Hematopoietic Stem Cell Transplantation in HLA-Identical Siblings

open access: yesFrontiers in Immunology, 2022
Induction of immunological tolerance has been the holy grail of transplantation immunology for decades. The only successful approach to achieve it in patients has been a combined kidney and hematopoietic stem cell transplantation from an HLA-matched or ...

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.
