Trypanosomatids of the genera and are parasites of medical and veterinary importance that infect mammals, including humans and domestic and wild animals. Among mammals, rodents and marsupials play a crucial role in maintaining and spreading the zoonotic transmission cycle of these parasites. The present study aimed to detect the natural occurrence of spp. and spp. in rodents and marsupials in the state of Amapá, northern Brazil. In total, 137 samples were analyzed, of which 19 (6 marsupials and 13 rodents) were positive for trypanosomatid DNA. Partial sequences of the 18S rRNA gene of trypanosomatids were obtained from 10 out of 19 positive samples. Specifically, an undescribed sp. was detected in , , and . was detected in a , whereas sequences close to and were obtained from and , respectively. Finally, () sp. was detected in , , and . The present study expands the knowledge about marsupials and rodents as hosts of trypanosomatids and emphasizes the need for further studies on the role of these animals as potential reservoirs of these parasites in the Amazon region.

Frugivory plays a crucial role in shaping Neotropical ecosystems, influencing plant dispersal, community dynamics, and ecosystem function. Despite its ecological significance, a systematic understanding of frugivore-fruit interactions spanning the entire Neotropical realm has been lacking. Therefore, we compiled the NeoFrugivory database, which addresses this gap by synthesizing data from a wide range of sources, including peer-reviewed literature, field studies, and existing databases.

This study aimed to identify species in small non-flying mammals captured in semi-deciduous forest fragments of the Atlantic Forest and pastures in the Southwest region of Bahia state, Northeast Brazil. A total of 445 animals belonging to 11 different species were captured, the majority being rodents (75.7%; 337), followed by marsupials (24.

The present study describes the morphology and phylogenetic position of two specimens of Bertiella Stiles et Hassall, 1902 (Cestoda, Anoplocephalidae) from Rattus tanezumi (Temminck) (Muridae) from Đồng Tháp Province in southern Vietnam. The phylogenetic analysis was based on sequences of the large subunit ribosomal RNA gene (28S). The specimens were described and shown to be morphologically similar to Bertiella anapolytica Baylis, 1934 from Rattus spp.

There is increasing interest in use of marsupial models in research, for use in next-generation conservation by improving fitness through genetic modification, and in de-extinction efforts. Specifically this includes dasyurid marsupials such as the Thylacine, Tasmanian devil, quolls and the small rodent-like dunnarts. Technologies for generating genetically modified Australian marsupials remains to be established.
