Current understanding of lymphoproliferative disease virus in wild turkeys

Wildlife Society Bulletin, Volume 49, Issue S1, December 2025.
Lymphoproliferative disease virus (LPDV) is a retrovirus that can cause a spectrum of disease in wild turkeys (Meleagris gallopavo), from subclinical infection to lymphoid tumors. We reviewed the literature to summarize our current understanding of LPDV, including disease presentation, surveillance, impact on fitness, spatiotemporal distribution, and ...

Detection of avian leukosis virus using polymerase chain reaction and enzyme linked immunosorbent assay [PDF]

, 2004
The applications of polymerase chain reaction (PCR) and enzyme linked immunosorbent assay (ELISA) in detecting avian leukosis virus (ALV) subgroups A and J were studied in a flock of breeder chickens. Out of 74 chickens tested 9, 36, 13 and 16 were found

Differentiated Presynaptic Input to OLMɑ2 Cells Along the Hippocampal Dorsoventral Axis: Implications for Hippocampal Microcircuit Function

Hippocampus, Volume 35, Issue 5, September 2025.
ABSTRACT The dorsal and ventral hippocampus have distinct processing properties, but it remains unclear if interneuron subtypes differ in connectivity along the dorsoventral axis. Oriens lacunosum‐moleculare (OLM) interneurons, identified by the Chrna2 gene, are known to regulate memory processes differently along this axis. OLMɑ2 cells bidirectionally

Risk of Mortality From Esophageal Cancer Among US Poultry Workers, 1950−2019

American Journal of Industrial Medicine, Volume 68, Issue 8, Page 711-723, August 2025.
ABSTRACT Background While research suggests poultry industry workers have an increased risk of cancer mortality, little is known about their risk of esophageal cancer mortality. We investigated the association between working with poultry and esophageal cancer mortality while concurrently investigating other occupational and nonoccupational risk ...

New developments in biotechnology applied to animals: An assessment of the adequacy and sufficiency of current EFSA guidance for animal risk assessment

EFSA Journal, Volume 23, Issue 8, August 2025.
Abstract EFSA was requested by the European Commission to provide a scientific opinion on new developments in biotechnology, including new genomic techniques, as applied to animals for food, feed and other agricultural uses. A horizon‐scanning exercise identified a variety of animals obtained with new genomic techniques, with the potential to reach the

Virus or Avian Myeloblastic Leukosis

Poultry Science, 1956
Abstract INTRODUCTION AVIAN leukosis is a complex of diseases which are not only of much economic importance, but which, in addition, comprise one category of virus-induced tumors. As a consequence, knowledge of the diseases is of fundamental interest in its bearing on the problem of cancer as a whole. Since the initial reports of the viral etiology
