Welfare and Physiological Consequences of Non‐Lethal Blood Sampling From the Caudal Vasculature of Atlantic Salmon (Salmo salar L.)

Journal of Fish Diseases, EarlyView.
ABSTRACT The objective of this study was to evaluate welfare and health effects following single and repeated non‐lethal blood sampling from the caudal vasculature of Atlantic salmon. Two experiments were conducted at three different temperatures: a 6‐week freshwater experiment with fish weighing 50–100 g, undergoing up to four blood withdrawals, and a

Mosquito and arbovirus surveillance in wetlands of South‐East England: Comparison of two adult mosquito traps, use of a novel trap with FTA™ cards and arbovirus testing

Medical and Veterinary Entomology, EarlyView.
Trap performance: Mosquito Magnet® captured significantly more mosquitoes overall, while BG‐Sentinel showed greater species evenness and was more effective for Culex pipiens s.l. and broader species representation. Spatial variation: Mosquito abundance and species composition varied significantly between wetlands, highlighting the importance of site ...

A multiplex assay to detect mosquito species, bloodmeal host source and Plasmodium in malaria vectors using Nanopore amplicon sequencing

Medical and Veterinary Entomology, EarlyView.
Insectary‐reared mosquitoes were simultaneously assessed for species identification, bloodmeal source analysis and Plasmodium detection, using a single multiplexed sequencing run on the MinION sequencing platform. The method was applied to 150 insectary‐reared mosquitoes, representing nine species blood‐fed with five vertebrate hosts and 40 samples for
