Wild Rodent Ectoparasites Collected from Northwestern Iran

Journal of Arthropod-Borne Diseases, 2017
Background: Rodents play an important role as reservoir of some pathogens, and the host of some ectoparasites as well. These ectoparasites can transmit rodents’ pathogens to human or animals.

Ultrasonographic and Endoscopic Findings of Pancreatic Adenocarcinoma With Duodenal Invasion in a Brown Bear (Ursus arctos)

Veterinary Radiology &Ultrasound, Volume 67, Issue 4, July 2026.
ABSTRACT This report describes a 25‐year‐old, intact male brown bear (Ursus arctos) presenting with weight loss, diarrhea, melena, apathy, and a 12% hematocrit. Ultrasound showed proximal duodenal wall thickening with submucosal cysts and a large, heterogeneous, highly vascularized mass in the descending duodenum, containing small gas pockets and ...

Discovery of an Adaptive Neuroimmune Response Driving Itch and Fast Tick Removal with Implications for Preventing Pathogen Transmission

Advanced Science, Volume 13, Issue 32, 9 June 2026.
Itch‐induced tick removal (IITR): An acquired neuroimmune mechanism, itch‐induced tick removal, develops after repeated tick exposure, mobilizing T cells and macrophages at the tick bite site to trigger a rapid scratching response that facilitates timely tick removal within a critical window that precedes the transmission of many tick‐borne pathogens ...

Influence of MC1R Gene Variants on Coat Color of Indicine Cattle Breeds

Animal Genetics, Volume 57, Issue 3, June 2026.
ABSTRACT Indicine cattle display a broad range of coat colors, representing a relevant and breed‐defining trait required for registration in breeder association. Among the genes involved in pigmentation, MC1R stands out for modulating the synthesis of melanin‐related proteins and remains poorly explored in indicine cattle breeds. Therefore, we aimed to

Networks of Indirect Contact Promote Spread of an Environmentally Transmitted Pathogen in a Highly Social Species

Ecology and Evolution, Volume 16, Issue 6, June 2026.
Using behavioral observations and network simulations, we evaluate direct and indirect transmission of the MTBC pathogen M. mungi in banded mongooses. Incorporating intergroup scent marking reveals that environmentally mediated, socially directed pathways can promote spread at low transmissibility, elevating population prevalence even when direct ...

Insights Into Tribal‐Level Adaptive Evolution and Phylogeny in Soricinae From Mitogenome of the Chinese Endemic Sorex cansulus

Ecology and Evolution, Volume 16, Issue 6, June 2026.
This study reveals that natural selection is the main force shaping the mitochondrial protein‐coding genes of zokors, with all five populations exhibiting strong purifying selection. Phylogenetic analysis and divergence time estimation strongly support the monophyly of the subfamily Soricinae, leading to key taxonomic revisions, including the ...

Vaccination against ectoparasites

Parasitology, 2006
Ectoparasites of livestock are of great economic and social importance but their effective control remains difficult. The feasibility of vaccination as a novel control measure was established over a decade ago with the commercial release of a recombinant vaccine against the cattle tickBoophilus microplus. Since then, research has continued on ticks and

Environmental and Protection Effects of Shark‐Companion Associations Across Three Ocean Basins

Ecology and Evolution, Volume 16, Issue 6, June 2026.
Companion species frequently associate with large marine hosts, yet the ecological drivers of these relationships remain poorly understood. Using a global dataset of midwater BRUVS deployments, we modelled the presence and abundance of shark‐companion associations across seven shark species and three ocean basins.

Variation in the Oxidative State of Collared Flycatcher (Ficedula albicollis) Nestlings and Its Association With Their Plumage Coloration

Ecology and Evolution, Volume 16, Issue 6, June 2026.
Plumage coloration is widely recognized as an important component in intraspecific communication. Our aim was to examine the variation of oxidative parameters and their associations with the coloration of two different nestling plumage traits in collared flycatchers (Ficedula albicollis).
