From Infection to Anxiety: A Sequential Model Linking Latent Toxoplasmosis to Psychological Distress via Health and Stress

Scandinavian Journal of Psychology, Volume 67, Issue 4, Page 1026-1043, August 2026.
ABSTRACT Identifying the drivers of chronic stress is crucial for understanding its impact on mental health. Latent toxoplasmosis, a widespread parasitic infection, has been linked to various psychological changes. The Stress‐Coping Hypothesis proposes that at least some of these changes are consequences of chronic stress arising from the infection's ...

Vector competence of Amblyomma americanum (Acari: Ixodidae) for Rickettsia rickettsii [PDF]

Ticks and Tick-borne Diseases, 2017
Rickettsia rickettsii - the etiologic agent of Rocky Mountain spotted fever (RMSF) - is widely spread across the Americas. In the US, Dermacentor spp. ticks are identified as primary vectors of R. rickettsii and Rhipicephalus sanguineus s.l. has been implicated in transmission of this pathogen in several locations in the Southwest. Conversely, ticks of

Anaphylactic transfusion reaction to group B platelets related to alpha‐gal syndrome: A case report

Transfusion, Volume 66, Issue 8, Page 1690-1693, August 2026.
Abstract Background Alpha‐gal syndrome (AGS), a distinct form of IgE‐mediated hypersensitivity to the carbohydrate galactose‐α‐1,3‐galactose (α‐Gal), typically occurs after repeated tick bites and leads to allergic reactions after ingestion of mammalian meat.

Challenging the Clinical Paradigm of Hepatozoon canis: A Primary Pathogen Causing Clinically Significant Disease at Low Parasitaemia and a Chronic Inflammatory State

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
Hepatozoon canis causes significant clinical disease even at low parasitaemia and induces chronic subclinical anaemia and inflammation in dogs. Lack of tick control is the main modifiable risk factor. Molecular diagnosis is far more sensitive than microscopy, challenging the traditional view that disease severity depends solely on parasite burden ...

Isolation, culture, and genome analysis of Rickettsia oklahomensis sp. nov. (Rickettsiales: Rickettsiaceae) from Amblyomma americanum (Acari: Ixodidae)

Ticks and Tick-Borne Diseases
An uncharacterized Rickettsia species was previously identified by molecular detection in Amblyomma americanum ticks from Oklahoma, a state reported to have high Rickettsia seroprevalence.

Cyberinfrastructure to support ecological forecasting challenges

Ecosphere, Volume 17, Issue 6, June 2026.
Abstract Ecological forecasting challenges, formalized efforts to empower the ecology community to develop near‐term iterative forecasts of yet‐to‐be‐collected data, are a powerful tool to advance predictive capacities in ecology. The National Ecological Observatory Network (NEON) Ecological Forecasting Challenge, which has processed over 82 million ...

Transfusion‐related alpha‐gal syndrome: Two new cases expanding the demographic and geographic spectrum, and evidence of a diagnostic gap in allergic transfusion reaction evaluation

Transfusion, Volume 66, Issue 6, Page 1167-1179, June 2026.
Abstract Background Transfusion‐related alpha‐gal syndrome (TRAGS) has recently been proposed as a cause of allergic transfusion reactions (ATRs) in which alpha‐gal‐specific IgE in sensitized group O (or potentially group A) recipients reacts with epitopes on group B or AB plasma‐containing components.

Amblyomma cajennense Sensu Stricto (Fabricius, 1787) and Amblyomma sculptum (Berlese, 1888) Tick Saliva Elicit Immune‐Modulatory Activity in Isolated Murine Macrophages With an Insight Into Proteomic Analysis

Parasite Immunology, Volume 48, Issue 3, March 2026.
ABSTRACT Tick saliva is known to cause immunosuppression and help pathogen transmission. Amblyomma sculptum is a public health concern as a vector of Rickettsia rickettsii. Another close‐related species is Amblyomma cajennense sensu stricto (s.s.). The impact of saliva from these species on murine macrophages remains unclear.
