Assessment of the Performance of Indirect Immunofluorescence Assay for Chagas Disease in Dogs Using a Reference Panel of Four Chimeric Proteins

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
We evaluated the performance of an indirect immunofluorescence (IIF) assay for detecting anti‐Trypanosoma cruzi IgG in dogs using four chimeric IBMP antigens and latent class analysis. The IIF assay showed suboptimal sensitivity and overall accuracy compared to ELISA and LCA‐based methods.

Ecology and evolution of pyrazines in insects

Biological Reviews, Volume 101, Issue 4, Page 1937-1959, August 2026.
ABSTRACT Chemical communication is the oldest and most widespread form of signalling among and within organisms. Among the many compounds involved in such communication, pyrazines – nitrogen‐containing heterocyclic molecules – are especially intriguing due to their widespread occurrence across the tree of life, from bacteria and fungi to insects and ...

Multi‐angle, cross‐domain fusion strategy enhances automated insect identification and hierarchical categorization: a case study on assassin bugs (Hemiptera: Reduviidae)

Cladistics, Volume 42, Issue 4, Page 358-373, August 2026.
Abstract Automated insect identification systems hold significant value for biodiversity monitoring, pest management, citizen science initiatives and systematic studies, particularly in an era of declining expertise in insect taxonomy. However, current deep learning approaches often rely on standardized specimen photos from limited‐angles and ...

Topographic Barriers and Lowland Corridors Structure Gene Flow in the Chagas Vector Rhodnius pallescens Across the Isthmian Forests

Journal of Biogeography, Volume 53, Issue 7, July 2026.
ABSTRACT Aim Biogeographic processes can profoundly shape the connectivity and evolutionary potential of arthropod disease vectors. We investigated how Panama's ecological and topographic transitions structure populations of the kissing bug Rhodnius pallescens, the primary vector of the Chagas disease agent Trypanosoma cruzi in the region.
