Diagnostic Performance of Rose Bengal, Competitive ELISA, and Native Hapten (NH) Assays in S19 Mass‐Vaccinated Cattle in an Endemic Brucellosis Environment

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Controlling bovine brucellosis requires reliable diagnostics and effective vaccination strategies. We evaluated the performance of three serological assays—the rose bengal test (RBT), competitive ELISA (cELISA), and agar gel immunodiffusion (AGID) with native hapten (NH)+lipopolysaccharide (LPS) antigen—following Brucella abortus S19 vaccination under ...

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Weissellosis, caused by the Gram‐positive (GP) lactic acid bacterium Weissella tructae, is an emerging disease of farmed rainbow trout (Oncorhynchus mykiss) reported in Asia, South and North America. In this study, W. tructae was isolated from diseased cultured trout in Costa Rica on four facilities with mortalities seen predominantly in sub‐adult (100–

Sustained contraceptive‐level plasma concentrations of 4,4′‐dinitrocarbanilide in free‐ranging urban feral pigeons fed a custom bait Niveles plasmáticos altos y sostenidos de 4,4′‐dinitrocarbanilida en palomas domésticas libres alimentadas con un cebo anticonceptivo

Wildlife Society Bulletin, Volume 49, Issue 4, December 2025.
We assessed the acceptability and consumption of a custom‐developed nicarbazin bait for feral pigeons, inferred its contraceptive efficacy, and evaluated the reversibility of its effects upon cessation of treatment. Only feral pigeons consumed the bait, except for one eared dove that also ingested the food. Continuous administration of this bait raised
