Cytauxzoon spp. are tick-borne haemoprotozoans that infect domestic and wild felids and are of increasing relevance in veterinary medicine and epidemiology of vector-borne pathogens. In Brazil, the genetic diversity of these agents in wild felids has been progressively expanded, culminating in the description of Cytauxzoon brasiliensis . However, the occurrence of this species in domestic cats is unknown. Therefore, the presen...

Primates can share parasites with humans, and understanding host-parasite interactions is essential for evaluating the condition of wild primates, ecological dynamics, and One Health interface, which integrates humans, animal, and environmental health in shared environments. One example is filarial nematodes of the genus Mansonella , for which a lack of in-depth studies of symptoms or blood alterations limits our understanding...

This case study examines the design of a self-sufficient ecovillage for the Xavante Indigenous people in Mato Grosso, Brazil. Ecovillages are sustainable, self-sufficient settlements that promote social, ecological, economic and cultural well-being. To our knowledge, only a few studies have considered ecovillage design in isolated areas. The Xavante are traditionally nomadic, but today they face food scarcity because they are...

Bovine anaplasmosis is a tick-borne rickettsial disease of significant sanitary and economic importance to livestock, particularly in tropical and subtropical regions, and is associated with high morbidity and reduced productivity. However, data on its molecular prevalence in cattle from semiarid and transitional areas of the Northeast region of Brazil remain scarce. This study aimed to determine the prevalence of Anaplasma sp...

Arboreal primates rely heavily on acoustic communication, making them ideal candidates for passive acoustic monitoring (PAM). Here, we investigated the detectability of vocalisations from Alouatta belzebul , Callithrix jacchus , Saimiri spp, and Sapajus flavius in three fragments of Atlantic Forest and two fragments of Caatinga Forest in northeastern Brazil. We recorded each area for 48 h per month over 7 months, placing one a...

The "Primates in Peril: The World’s 25 Most Endangered Primates" list, also known as the Top 25 list, has been published every two years since 2000. Its goal is to boost conservation efforts for these primates. The Top 25 list only includes threatened species according to the IUCN Red List classification and aims for balanced species representation. Analyzing species threats could complement this approach, offering insights to...

Lactiplantibacillus plantarum M2, previously isolated from the Amazonian fruit Humiria balsamifera , has shown a promising probiotic profile. This study performed an integrated safety evaluation combining genome-informed analyses with a 28-day repeated-dose oral toxicity assessment in a murine model. In silico genome screening revealed no detectable signatures associated with pathogenicity, virulence, or acquired antimicrobial...

This study assessed the effects of dietary shrimp head meal (SHM) on growth performance, metabolism, antioxidant status, and health of Nile tilapia ( Oreochromis niloticus ) fingerlings. Five isonitrogenous and isoenergetic diets were precisely formulated on a digestible nutrient basis, containing graded SHM levels (0, 5, 10, 15, and 20%), and fed for 45 days to fish (3.24 ± 0.07 g) reared in 50 L tanks (10 fish tank −1 ; four...
