Abstract

Brown adipose tissue fulfills multiple vital functions for bats, in addition to playing an important epidemiological role in the localization and maintenance of certain pathogens. However, there is no data regarding the presence of this tissue in specimens from our region, so the objective of this study was to identify brown adipose tissue in insectivorous bats from the city of Corrientes. We worked with 11 specimens captured between April and July, successfully identifying macroscopically, in all studied bats, three well-defined regions of brown fat localization: inter-scapular, axillary, and gonadal, which were histologically confirmed. These results represent the first identification data of brown adipose tissue in bats from the city of Corrientes, contributing to the knowledge of bats in our region and establishing in future works, together with other characteristics, the potential role of brown fat and its relationship with pathogens in different bat species.
