Trematode Infection Prevalence Increases With Snail Richness: Observations From a 4‐Year Study of Snail–Trematode Interactions

Ecology and Evolution, Volume 15, Issue 10, October 2025.
We find that higher snail richness correlated with increased overall and generalist trematode infections, while specialist infections showed a similar but nonsignificant trend. The study also highlighted potential host‐switching events and the impact of long‐term sampling on parasite communities, emphasizing the need for continued monitoring of host ...

Unexpected trophic diversity in the endemic fish Orestias chungarensis in a high‐altitude freshwater ecosystem, Lake Chungará (4520 m), northern Chile

Journal of Fish Biology, Volume 107, Issue 3, Page 837-850, September 2025.
Abstract Orestias chungarensis Vila & Pinto, 1986 is a small‐bodied (max fork length = 120 mm) cyprinodontiform fish with a very restricted global distribution. The species is limited to a single, small (283 km2), high‐altitude (4520 m) catchment located in the Altiplano of northern Chile. Until the late 20th century, O.

Pharmacological Inhibition of c‐Jun N‐Terminal Kinase Activity Exacerbates Liver Damage in Schistosoma mansoni Infected Mice

Liver International, Volume 45, Issue 9, September 2025.
ABSTRACT Background and Aims Schistosomiasis is a neglected tropical disease affecting more than 250 million people worldwide. Eggs of the parasitic helminth S. mansoni cause major morbidity in the liver, spleen and intestine. Of note, egg‐released soluble antigens (SEA) induce the transcription factor c‐Jun in hepatocytes, promoting hepatocellular ...

Enhancing schistosomiasis drug discovery approaches with optimized proteasome substrates

Protein Science, Volume 34, Issue 6, June 2025.
Abstract Schistosomiasis, a neglected tropical disease infecting over 200 million people globally, has limited therapeutic options. The 20S proteasome is a validated drug target for many parasitic infections, including those caused by Plasmodium and Leishmania, and we have previously demonstrated antischistosomal activity with inhibitors targeting ...

Co‐endemicity of schistosomiasis and tegumentary leishmaniasis: Spatial co‐clustering in endemic areas

Tropical Medicine &International Health, Volume 30, Issue 6, Page 556-568, June 2025.
Abstract Objectives Schistosomiasis and tegumentary leishmaniasis simultaneously affect areas in tropical and subtropical regions. Co‐infected individuals show a less‐than‐optimal response to treatment and increased regulatory immune responses. However, no study has determined where Schistosoma–Leishmania co‐infections are more likely to occur ...

South American Great Basin: Limnogeological analysis of the Salina del Bebedero Basin, Argentina (Late Pleistocene‐recent)

The Depositional Record, Volume 11, Issue 2, Page 739-763, April 2025.
. The Bebedero tectonic depression in San Luis province, Argentina, is a closed drainage basin that has formed as a result of block‐faulting and rifting processes. The Bebedero lake exhibits notable similarities to the endorheic watersheds of the western United States, particularly those of Death Valley, the Saline Valley and, to a lesser extent, the ...
