Evaluation of a Novel Tc‐24 Recombinant Antigen ELISA for Serologic Detection of Trypanosoma cruzi Infection in Dogs: A Pilot Study

Veterinary Medicine and Science, Volume 11, Issue 5, September 2025.
Dogs are major reservoirs of Trypanosoma cruzi in Texas, United States. This study evaluated a novel Tc‐24 recombinant antigen ELISA for the serologic detection of Chagas disease in dogs and found it to have high sensitivity and specificity compared to existing commercial tests. The Tc‐24 Chagas ELISA provides a reliable tool for enhanced canine Chagas

Abundant triatomines in Texas dog kennel environments: Triatomine collections, infection with Trypanosoma cruzi, and blood feeding hosts

Acta Tropica
Triatomine insects are vectors of the protozoan parasite Trypanosoma cruzi- the causative agent of Chagas disease. Chagas disease is endemic to Latin America and the southern United States and can cause severe cardiac damage in infected mammals, ranging from chronic disease to sudden death. Identifying interactions among triatomines, T.

In Vitro Leishmanicidal Efficacy of Synthesized Arylidene Analogues of Glitazone

Drug Development Research, Volume 86, Issue 5, August 2025.
ABSTRACT Diabetes is a fast‐growing health issue in low‐ and middle‐income countries, with ~80% of diabetics living in the tropics and sub‐tropics. It is a deadly condition claiming the lives of millions of individuals annually, with no therapeutic treatment available to date. The management of diabetes is thus limited to symptomatic relief by glycemic

First Report of Aprostocetus asthenogmus (Hymenoptera: Eulophidae) in South America and Parasitizing Eggs of Triatominae Vectors of Chagas Disease

Journal of Parasitology Research, 2014
We report for the first time the parasitism of eggs of two triatomine Chagas disease vectors, Triatoma infestans and T. vitticeps, by the microhymenopterous parasitoid Aprostocetus asthenogmus. We also describe the first identification of this parasitoid

The salivary gland transcriptome of Varroa destructor reveals suitable targets for RNAi‐based mite control

Insect Molecular Biology, Volume 34, Issue 4, Page 540-551, August 2025.
RNAseq and differential expression analysis identified 15 salivary gland genes encoding secreted proteins with putative anti‐bacterial, anti‐fungal, cytolytic, digestive and immunosuppressive function. The three most highly transcribed genes were selected to study their functional importance by reverse genetics, using a non‐invasive approach of dsRNA ...

Vector-borne transmission of Trypanosoma cruzi among captive Neotropical primates in a Brazilian zoo [PDF]

, 2016
Background: Neotropical primates are important sylvatic hosts of Trypanosoma cruzi, the etiological agent of Chagas disease. Infection is often subclinical, but severe disease has been described in both free-ranging and captive primates.

Trypanosoma cruzi in triatomines from Nuevo Leon, Mexico

Salud Pública de México, 2007
To determine the prevalence of Trypanosoma cruzi in triatomines from Nuevo León using the standardization of an improved enzyme-linked immunosorbent assay test.From July to September 2005, 52 triatomines were captured in General Terán, a municipality located in Nuevo León. They were analyzed using optical microscopy (OM) and a polymerase chain reaction

Trypanosoma cruzi/Triatomine Interactions—A Review

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)
