A new species of is described in wild neotropical otters, , occurring in Corrientes, Argentina, based on morphological and molecular characteristics. Worms were located in the subcutaneous tissue from two of five investigated otters. n.

Influence of extraordinary floods on wildlife parasites: the case of gastrointestinal helminths and protozoa of wild canids from the Iberá Ecoregion, Argentina.

Parasites are natural components of ecosystems and play a significant role in the dynamics of wild animal populations. Although the environment of parasites is primarily defined by the host, most life cycles involve stages that must endure external conditions. Rainfall and flooding events are important factors that might influence the transport of parasitic stages, altering soil moisture levels, and resulting in a favorable environment for parasite survival and development.

Helminth infracommunity in a maned wolf, Chrysocyon brachyurus, from the humid Chaco, Argentina.

Parasitism is an important factor in conservation worldwide, especially for endangered species, as it can affect host populations by reducing growth rates, fecundity and affecting nutritional status. The maned wolf Chrysocyon brachyurus, a near-threatened species, is distributed across different habitats from the south Amazonian forest in Brazil to northern Argentina, Paraguay and eastern Bolivia. Most studies on gastrointestinal parasites in wild maned wolves are based on coprological findings, and there is little information about adult parasites and parasite species richness.

Coagulative modifications in patients with systemic sclerosis treated with iloprost or nifedipine.

This study compared iloprost and nifedipine to ascertain whether they could improve parameters of endothelial and platelet functions in the treatment of Raynaud's phenomenon secondary to systemic sclerosis. Thirteen patients affected by systemic sclerosis were treated with intravenous infusion of iloprost, and 7 patients were treated with oral nifedipine. Blood samples were taken at baseline and after 6 and 12 months of therapy to assess main serological indexes of endothelial damage, thrombin activation, fibrinolysis, as well as natural inhibitors of coagulation.
