Pathological and parasitological characterization of Prosthenorchis elegans in a free-ranging marmoset Callithrix geofroyi from the Brazilian Atlantic Forest

Pesquisa Veterinária Brasileira
: Prosthenorchis elegans is an acanthocephalan intestinal parasite reported in neotropical primates. Despite parasitism by P. elegans having already been described in wild marmosets in the Brazilian Atlantic Forest, there are no reports of this infection

Hodgkin and non‐Hodgkin lymphomas in the post‐antiretroviral therapy era according to HIV virological suppression

HIV Medicine, EarlyView.
Abstract Objectives Lymphomas remain among the most frequent HIV‐associated malignancies, with risk persisting despite effective virological control. This study describes the clinical, epidemiological and prognostic characteristics of lymphomas (both Hodgkin [HL] and non‐Hodgkin [NHL]) in people living with HIV (PLWH), according to virological ...

Systematics of Marmosa Subgenus Micoureus With Emphasis in ‘rapposa’ Group (Didelphidae, Marmosini): Geographic Variation and Revalidation of M. budini

Zoologica Scripta, EarlyView.
ABSTRACT Micoureus is the most species‐rich subgenus within the genus Marmosa. Conflicting arrangements regarding the number of species comprising this subgenus have been proposed and the validity of M. budini has been debated. Here, we used an approach integrating genetic and morphological data were conducted to reanalyze the ‘rapposa’ group ...

Trapped in the web: network architectures spread coevolution and shape adaptation

Oikos, Volume 2026, Issue 7, July 2026.
Adaptation is critical for biodiversity to persist under global change. Within ecological communities, species often face tradeoffs between adapting to shifting abiotic conditions and navigating the complex selective pressures imposed by interaction networks.

Sus1 Modulates Chromatin Remodeling and Gene Expression via the Cell Wall Integrity Pathway in Saccharomyces cerevisiae

The FASEB Journal, Volume 40, Issue 9, 15 May 2026.
Cell wall stress in yeast triggers transcriptional reprogramming through the CWI pathway. This study identifies Sus1, a subunit of SAGA and TREX‐2, as a key regulator in this process. Sus1 associates with stress‐responsive genes, promoting pre‐initiation complex assembly, chromatin remodeling, and RNA Pol II progression independently of H2B ...

Host–Parasite Interaction Networks of Helminths of Sigmodontine Rodents in Two Different Areas of the Brazilian Atlantic Forest

Ecological Research, Volume 41, Issue 3, May 2026.
Two helminth‐rodent networks were analyzed for two distinct areas. Network modularity, nestedness, and degree of specialization were calculated for each network. Higher network modularity than nestedness and high network specialization were observed in both networks, suggesting functional and/or taxonomic specialization between helminth species and ...

First Description and Characterisation of Lactococcus garvieae Strains Causing Septicaemic Disease in Farmed Sea Bass (Dicentrarchus labrax; Linnaeus) in Spain

Journal of Fish Diseases, Volume 49, Issue 5, May 2026.
ABSTRACT This study presents the first description and characterisation of Lactococcus garvieae isolated from diseased European sea bass (Dicentrarchus labrax) farmed in Spain. During autumn 2023, two fish farms were affected by infectious outbreaks causing moderate cumulative fish mortality (5%–10%). Diseased fish showed clinical signs of haemorrhagic

Historical shifts, geographic biases, and biological constraints shape mammal species discovery

Journal of Systematics and Evolution, Volume 64, Issue 3, Page 536-547, May 2026.
Taxonomic descriptions of mammals have become more robust from 1990 to 2025, with increased specimen sampling, broader comparisons, and more integrative methods. However, disparities remain: tropical and small‐bodied species are less comprehensively described, reflecting ongoing geographic and biological biases.
