Molecular diagnostics evaluated for trypanosomes in Neotropical bats

Researchers have conducted a study to establish and optimize molecular diagnostic methods for detecting trypanosomes in Neotropical bats, specifically focusing on the species Artibeus jamaicensis and Artibeus lituratus in Panama. The research aims to better understand the role these bats play in the transmission of Chagas’ disease, a zoonotic infection caused by the parasite Trypanosoma cruzi.

The study evaluated several biomolecular approaches, including fluorescence in situ hybridization (FISH) and various polymerase chain reaction (PCR) assays. Findings indicated that while FISH was optimized through various fixation and hybridization strategies, it lacked sufficient sensitivity for reliable detection in field-derived blood smears. The research emphasizes the need for reliable molecular tools to characterize parasite diversity in wildlife hosts without oversimplifying ecological relationships.
