Transboundary Animal Diseases Associated With Cross‐Border Camel Movement. A Systematic Review and Meta‐Analysis

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Transboundary animal diseases (TADs) are contagious diseases that significantly impact livestock health, public health and economic stability. In regions with frequent cross‐border trade and transhumance involving camels, particularly the Middle East and Africa, TADs pose a heightened One Health risk due to their zoonotic potential and capacity to ...

Same data, different results? Machine learning approaches in bioacoustics

Methods in Ecology and Evolution, Volume 16, Issue 8, Page 1574-1586, August 2025.
Abstract Automated acoustic analysis is increasingly used in behavioural ecology, and determining caller identity is a key element for many investigations. However, variability in feature extraction and classification methods limits the comparability of results across species and studies, constraining conclusions we can draw about the ecology and ...

On the Lack of Domestic Dogs in Pre‐Columbian Lowland Amazonia and Their Deep History of Entanglements With Humans in South America

The Journal of Latin American and Caribbean Anthropology, Volume 30, Issue 2, June 2025.
ABSTRACT Data from archaeology, ethnography, and ethnohistory document entanglements of dogs among South American Indigenous societies during pre‐Columbian and colonial times. The prolific presence and uses of dogs in the Central Andes and in parts of the Paraná Basin, Patagonia, and Circum‐Caribbean regions contrast with the conspicuous lack of ...

Anthelmintic resistance in gastrointestinal nematodes of alpacas (Vicugna pacos) in Australia

Parasites & Vectors, 2018
Background Gastrointestinal nematodes (GINs) can cause significant economic losses in alpacas due to lowered production of fibre and meat. Although no anthelmintics are registered for use in alpacas, various classes of anthelmintics are frequently used ...

Taming interleukin‐12: Engineering of bispecific antibody‐based IL‐12 mimetics with biased agonism capacities

Protein Science, Volume 34, Issue 3, March 2025.
Abstract In this work, we have generated bispecific interleukin (IL)‐12 surrogate agonists based on camelid‐derived single‐domain antibodies (sdAbs) targeting the IL‐12 receptor (IL‐12R) subunits IL‐12Rβ1 and IL‐12Rβ2. Following immunization and antibody display‐based paratope isolation, respective sdAbs were combinatorially reformatted into a ...

Characterization of paneth cells in alpacas (Vicugna pacos, Mammalia, Camelidae)

Tissue and Cell, 2016
Paneth cells are secretory epithelial cells of the innate immune system of the intestine of several mammals, including alpacas. Little is known about the latter; thus, in the present study we described the morphology and histochemical characteristics of Paneth cells in healthy fetuses, and young and adult alpacas. For this purpose, samples of duodenum,
