Validating Wing Biopsies for Blood‐Borne Pathogen Characterization in Bats

Molecular Ecology, Volume 35, Issue 19, October 2026.
ABSTRACT Wildlife surveillance is critical for tracking disease emergence, characterizing pathogen diversity, and assessing spillover risks. Blood‐borne pathogens are of particular interest for such efforts due to their global distribution, broad host taxa, and zoonotic potential.

Microbiome‐mediated chemical communication in insects: Implications for pest management

Pest Management Science, Volume 82, Issue 9, Page 8132-8151, September 2026.
Microbiome–semiochemical interactions involve the following processes: direct microbial synthesis, host gene regulation, precursor biotransformation, microbiome modulation and indirect ecological signaling. Abstract Insects rely on semiochemicals to regulate aggregation, mating, foraging, and host selection. This review synthesizes evidence that insect‐

Humans as blood-feeding sources in sylvatic triatomines of Chile unveiled by next-generation sequencing [PDF]

, 2023
Background Triatomines are blood-sucking insects capable of transmitting Trypanosoma cruzi, the parasite that causes Chagas disease in humans. Vectorial transmission entails an infected triatomine feeding on a vertebrate host, release of triatomine ...

Correlation between infection rate of triatominies and Chagas Disease in Southwest of Bahia, Brazil: a warning sign?

Anais da Academia Brasileira de Ciências, 2016
Chagas disease, caused by the Trypanosoma cruzi, has a wide distribution in South America, and its main method of control is the elimination of triatomines. It is presented here the geographic distribution and the rate of natural infection by T. cruzi of

<i>Trypanosoma cruzi</i>/Triatomine Interactions-A Review. [PDF]

Pathogens
This review summarizes the interactions between Trypanosoma cruzi, the etiologic agent of Chagas disease, and its vectors, the triatomines, and highlights open questions. Four important facts should be emphasized at the outset: (1) The development of T. cruzi strains and their interactions with the mammalian host and the insect vector vary greatly. (2)

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.

Peridomestic structure, farming activity and triatomine infestation [PDF]

Parasite, 2006
The role of peridomestic structure and farming activity on triatomine infestation was studied on two vector species of Chagas disease (Triatoma pseudomaculata and T. brasiliensis) in Bahia State, northeastern Brazil. A randomly selected population issued from 136 farms was divided into four categories according to the householder activity.

Scalable Access to N‑Acylindole Linkages: Enabling the Synthesis of Antitrypanosomal Noncanonical Cyclic Peptides for Chagas Disease

Angewandte Chemie, Volume 138, Issue 15, 6 April 2026.
A gram‐scale supply of bulbiferamide A, which features a rare N‐acylindole linkage and possesses potent inhibitory activity against Trypanosoma cruzi epimastigotes (IC50 = 4.1 µM)—the causative parasite of Chagas disease—was successfully achieved. Moreover, the cyclization strategy developed in this study facilitated the synthesis of noncanonical ...
