Latin American countries produce more than a quarter of the world's beef and are a major global supplier of livestock protein. Tick-borne diseases (TBDs) are a major constraint to the livestock industry worldwide, including in Latin America. The aim of this study was to detect and characterise tick-borne pathogens in cattle from Santa Cruz, Bolivia, where no detailed epidemiological data are available. Blood samples were collected from 104 cattle. Apicomplexan parasites were detected by nested PCR amplification of the 18S ribosomal RNA gene (rDNA), and was screened by the PCR amplification of 16S rDNA, followed by characterisation based on the heat shock protein and citrate synthase gene sequences. infection was observed in nine cattle (one and eight ), while infection was detected in thirty-two cattle. A sequencing analysis confirmed the presence of and -like. These results provide the first molecular evidence for the four above-mentioned tick-borne pathogens in cattle in Bolivia. This information improves our understanding of the epidemiology of TBDs and will help in formulating appropriate and improved pathogen control strategies.

In South America, Pseudosuccinea columella, Galba cubensis, Galba schirazensis, and Galba truncatula snails serve as vectors of Fasciola hepatica, posing significant challenges to public and animal health. This study identified environmentally suitable areas for these species using ecological niche models, including Maxent, Random Forest, and Support Vector Machine (SVM) models. Occurrence points (n = 797) were compiled from the international literature, following the PRISMA protocol, and the malacological collection of the FIOCRUZ Institute in Rio de Janeiro, Brazil.

Bolivian Creole cattle populations evolved under low levels of breeding management and, during more than 500 years of natural selection, became adapted to various environments such as the contrasting highland and subtropical environments. Recently, highland Creole cattle were crossbred with Holstein to improve dairy production. The aim of this research was to evaluate the divergent adaptation through selection footprints of Bolivian Creole cattle from Andean highland and tropical lowlands, and to evaluate the effect of Holstein introgression in highland Creole.

Fascioliasis is a tropical zoonotic disease caused by liver flukes ( and ) mostly in sheep, goats, and cattle. It is a prevalent infection in developing countries like Bolivia, Peru, and Egypt, affecting both humans and livestock. It remains under-reported due to lack of awareness.

Babesia bigemina and Theileria annulata are tick-borne protozoans that cause piroplasmosis in cattle, resulting in huge damages to the livestock industry. The prevalence of these infections depends on various intrinsic and extrinsic risk factors. In Pakistan, there is no information regarding the molecular characterization of Babesia bigemina and the risk factors associated with piroplasmosis.

Studies of reproductive biology and resources availability to floral visitors by plant species are important to understand the plant-pollinator interactions that drive species adaptation. We aim to understand the relationship between reproduction mechanisms of Deuterocohnia meziana (Bromeliaceae) and pollinators. The species occurs in Bolivia and Paraguay, and it is the only species of the genus found in Brazil, where it is restricted to ironstone outcrops.
