The impact of invasive alien species on threatened and endangered species: A geographic perspective

Wildlife Society Bulletin, Volume 48, Issue 4, December 2024.
To help guide recovery efforts, we document how invasive alien species (IAS) impact threatened and endangered species (T&ES) under the Endangered Species Act. Our research shows that 58% of T&ES (n = 1,545) were impacted by IAS, with Pacific Island species (97%) facing greater threats from IAS compared to Mainland (38%) and Atlantic Island species (22%)

Necrotic skin lesion in a dog attributed to Loxosceles (brown spider) bite: a case report

Journal of Venomous Animals and Toxins including Tropical Diseases, 2009
Envenomations caused by Loxosceles (brown spider) have been reported throughout the world. Clinical signs associated to bites of these spiders involve dermonecrotic lesions and intense local inflammatory response, besides systemic manifestations such as ...

Discovery of broadly‐neutralizing antibodies against brown recluse spider and Gadim scorpion sphingomyelinases using consensus toxins as antigens

Protein Science, Volume 33, Issue 3, March 2024.
Abstract Broadly‐neutralizing monoclonal antibodies are becoming increasingly important tools for treating infectious diseases and animal envenomings. However, designing and developing broadly‐neutralizing antibodies can be cumbersome using traditional low‐throughput iterative protein engineering methods. Here, we present a new high‐throughput approach

Recombinant Protein Containing B-Cell Epitopes of Different Loxosceles Spider Toxins Generates Neutralizing Antibodies in Immunized Rabbits

Frontiers in Immunology, 2018
Loxoscelism is the most important form of araneism in South America. The treatment of these accidents uses heterologous antivenoms obtained from immunization of production animals with crude loxoscelic venom.
