Cuticular Lipids as a First Barrier Defending Ixodid Ticks against Fungal Infection

Journal of Fungi, 2022
The chemical composition of tick cuticles acts as a barrier to pathogens and may limit infection by entomopathogenic fungi. This study characterized the cuticular neutral lipids (NL) and hydrocarbons (HCs) of four ixodid ticks that are widely distributed

Proteasomal degradation of intracellularly expressed Amblyomin‐X limits suicide gene therapy potential in melanoma cells

FEBS Open Bio, Volume 16, Issue 8, Page 1602-1614, August 2026.
This study explores the feasibility of expressing the antitumoral protein Amblyomin‐X through a suicide gene therapy approach and investigates its intracellular fate after gene delivery. Although the gene is efficiently expressed, melanoma cells rapidly degrade the Amblyomin‐X protein via proteasome activity.

Host, vector, and parasite dynamics: exploring intrinsic and extrinsic factors shaping tick‐borne filarial nematode transmission

Biological Reviews, Volume 101, Issue 4, Page 1779-1792, August 2026.
ABSTRACT Tick‐borne filarial nematodes are a complex and understudied group of parasites that rely on ticks for transmission in vertebrates. This review examines how intrinsic and extrinsic factors may influence the successful transmission of filarial nematodes in tick vectors, drawing insights from extensively studied haematophagous dipteran vector ...

Epidemiology of capybara-associated Brazilian spotted fever.

PLoS Neglected Tropical Diseases, 2019
BACKGROUND:Brazilian spotted fever (BSF), caused by the bacterium Rickettsia rickettsii, has been associated with the transmission by the tick Amblyomma sculptum, and one of its main hosts, the capybara (Hydrochoerus hydrochaeris).

Diversity of tick species (Acari: Ixodidae) in military training areas in Southeastern Brazil

Revista Brasileira de Parasitologia Veterinária, 2022
Tick-borne pathogens belong to one of the two main groups of occupational biohazards, and occupational exposure to such agents puts soldiers at risk of zoonotic infections, such as those caused by rickettsiae.

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.
