Meta‐Analysis of the Efficacy of Spirulina Intervention in Mitigating the Negative Impact of Heat Stress on Production Physiology and Health Indices of Broilers

Journal of Animal Physiology and Animal Nutrition, Volume 110, Issue 1, Page 23-34, January 2026.
ABSTRACT There is an increasing number of published studies on the effect of spirulina (an aquatic plant known for its high nutritional value and potential health benefits) intervention on productivity and health of heat‐stressed broilers. However, the effect of spirulina intervention on the performance of broilers exposed to heat stress is poorly ...

Phylogeny, systematics and evolution of mimicry patterns in Neotropical limenitidine butterflies

Systematic Entomology, Volume 51, Issue 1, January‐March 2026.
The most comprehensive phylogeny for Adelpha reveals that it is not monophyletic, supporting the description of the new genus Adelphina for the alala‐group. The rate of mimicry evolution increases towards the tropics, consistent with the hypothesis of stronger biotic interactions near the equator.

Complementary genomic and morphological data elucidate the phylogeny of obscure darkling beetles (Blaptinae: Platynotini: Eurynotina)

Systematic Entomology, Volume 51, Issue 1, January‐March 2026.
First comprehensive phylogenomic study of subtribe Eurynotina using a combined dataset of 499 nuclear loci, 12 mitochondrial loci and 91 morphological characters covering all genera and species groups is presented. Eurynotina is monophyletic and genera within are redefined based on reassessment of old characters, generation of new characters, and ...

Beyond FoxP3—Identification of a Chicken Regulatory T Cell Signature

European Journal of Immunology, Volume 55, Issue 12, December 2025.
Chicken FOXP3+ putative regulatory T cells were identified using both bulk and single‐cell RNA sequencing to define their transcriptional signature and flow cytometry to confirm surface marker expression. This combined approach revealed a distinct putative Treg subset characterized by CD4, CD25, and GITR surface expression. ABSTRACT Regulatory T cells (

The Presence of Immunoglobulin in the Bursa of Fabricius ,

Poultry Science, 1967
Abstract Three-week-old birds were immunized with 40 mg. bovine serum albumin (BSA) per Kg. body weight. The bursa of Fabricius was removed 30 minutes after BSA injection and from another group of birds at 24-hour intervals for 5 consecutive days. The bursa was frozen −25°C. and sectioned in a cryostat (−25°C.) at 4 mμ.

Histomorphology of bursa of Fabricius: effects of stock densities on commercial broilers

Brazilian Journal of Poultry Science, 2006
During the past few years, there has been considerable interest on the effects of stocking density on broiler behavior and immunity. Stress may cause immunodeficiency by affecting cell and humoral responses, as well as body weight decrease, and foot-pad ...

The Bursa of Fabricius and Homograft Immunity

Poultry Science, 1965
Abstract Hieronymus Fabricius (1621) reported the existence of a sac in the podex of the hen which he believed served as a semen receptable. (Apparently he didn’t notice its presence in cocks). Named the Bursa of Fabricius in his honour, the function of this organ was unknown until the discovery of its role in antibody production by a remarkable ...
