Cellular immune response of Amblyomma sculptum and Amblyomma americanum to entomopathogenic fungi: Implications for biological tick control

Medical and Veterinary Entomology, EarlyView.
Amblyomma sculptum showed a plasmatocyte‐dominant haemocyte profile. Beauveria bassiana increased plasmatocytes and reduced granulocytes, whereas Metarhizium robertsii did not cause significant changes. Amblyomma americanum showed a granulocyte‐dominant haemocyte profile. Beauveria bassiana reduced total haemocytes and granulocytes. B.

The potential for use of haematological and anti-IgE humoral responses as phenotypic markers for tick resistance in cattle

Current Research in Parasitology and Vector-Borne Diseases
Approximately 80% of the global cattle population is at risk of infestation and infection by ticks and tick-borne diseases (TTBDs). The economic losses from animal mortality, reduced production, vector control costs and animal treatment are very ...

High prevalence of a host‐associated Anaplasma lineage in wild coatis (Nasua nasua) from the Brazilian Atlantic Forest

Medical and Veterinary Entomology, EarlyView.
Anaplasma sp. DNA was detected in 47.9% of free‐ranging coatis (Nasua nasua) sampled in Iguaçu National Park, southern Brazil. Molecular analyses revealed a genetically distinct Anaplasma lineage infecting coatis, differing from Anaplasma strains detected in associated tick populations.

Geographical distribution of Hyalomma marginatum Koch, 1844 in northwestern Spain from 2019 to 2024: A one health approach

Medical and Veterinary Entomology, EarlyView.
This study confirms the presence of the tick Hyalomma marginatum Koch, 1844, a known vector of the Crimean‐Congo hemorrhagic fever virus at Galicia. Most ticks were encountered on humans and livestock, with numbers rising between 2019 and 2024, especially during spring and in warm‐summer Mediterranean southwest areas of the studied region.

Chain Reactions: How Businesses Plan to Respond to the EU Deforestation Regulation in Brazil, the Congo Basin, and Europe

Regulation &Governance, EarlyView.
ABSTRACT The 2023 European Union Regulation on Deforestation‐free Products (EUDR) is a transnational regulation aimed at addressing forest loss along the value chains of forest‐risk commodities. Grounding our analysis in new institutional theory with distinct behavioral drivers explaining actor behavior, and using qualitative methods, we draw on the ...
