Landim pigs, a population of native pigs from Mozambique are currently threatened by the recent introduction of European exotic breeds. Like most African pig populations, Landim pigs have never been characterized at the genome level and are well adapted to harsh conditions which include adaptation to endemic diseases. In this study, we provide a comprehensive genetic characterization of Landim pigs using whole-...
In Angola, about 70% of the population relies on subsistence agriculture, with cattle production crucial to the economy and culture of the southern regions. Local cattle breeds face extinction due to crossbreeding with improved breeds or replacement by exotic commercial breeds, risking the loss of unique genetic traits vital for adapting to Angola's ecosystems. This project aims to establish a biobank represent...

Natural and artificial selection in African sheep populations has left distinctive genomic signatures. In southern Angola, pastoralist tribes breed fat-tailed sheep adapted to arid and mesic savannas for protein and cultural purposes. This study aims to identify candidate genes associated with productivity and adaptation in these sheep. We sequenced genomes from Namibe (n = 3) and Cunene (n = 5) and compared th...
The goal of this study is the development of a high-quality assembly for the Pecari tajacu species. The Suoidea superfamily groups 2 families: Suidae and Tayassuidae. Suidae species inhabit Africa and Eurasia, occupying a wide range of habitats. The same applies to the Tayassuidae species that live in the Americas and were the first from Suoidea to diverge from their common ancestor in North America ~36 Ma. Lin...
cattle in Angola and how they relate to other breeds. In Africa we find Bos taurus and Bos indicus cattle and a hybrid also known as Sanga cattle. The most dominant cattle in Angola are Sanga which name varies according to the location and native language of the region, existing 11 different denominations, which conservation status in unknown. Sampling was performed between 2023 and 2024 in different provinces....
Oral contamination with Toxoplasma gondii oocysts shed by cats into the environment has been linked to severe outbreaks of human toxoplasmosis. Pigeons (Columba livia) are highly susceptible to oral infection with oocysts and indirectly indicate soil contamination, since they feed from the ground. A seroprevalence study was performed on cats and pigeons captured in the city of Lisbon. Serum samples collected fr...

Abstract Bovine besnoitiosis is caused by Besnoitia besnoiti, an obligate intracellular apicomplexan parasite. Affected animals present cutaneous and systemic manifestations and the disease may lead to considerable economic losses. Although generally associated to tropical and subtropical areas, bovine besnoitiosis is now considered an emergent disease in Europe, due to the increasing number of new cases and ap...
