Disease Agents inAmblyomma americanumfrom Northeastern Georgia [PDF]

Journal of Medical Entomology, 2004
Amblyomma americanum (lone star tick) is known or suspected to vector several organisms that are implicated as human pathogens, including Ehrlichia chaffeensis, E. ewingii, and Borrelia lonestari. These three agents have also been detected in white-tailed deer (Odocoileus virginianus). Because northeastern Georgia has a high abundance of both lone star

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.

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

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.

IgE to Galactose‐α‐1,3‐Galactose (α‐Gal) and Relevance to Ustekinumab First‐Dose Infusion Reactions and Allergenicity

JGH Open, Volume 10, Issue 2, February 2026.
ABSTRACT Aims Ustekinumab, a monoclonal antibody (mAb) used to treat inflammatory bowel disease, has been associated with immediate hypersensitivity reactions during first intravenous infusion. While rare, the mechanism for these reactions is unclear. IgE to the oligosaccharide galactose‐α‐1,3‐galactose (α‐gal) is a cause of allergy to mammalian meat ...
