Phylogenetic Inferences Based on Distinct Molecular Markers Confirm a Novel Babesia Species (Babesia goianiaensis nov. sp.) in Capybaras (Hydrochoerus hydrochaeris) and Associated Ticks

Microorganisms, 2023
Piroplasmids (order Piroplasmida) are a diverse group of tick-borne protozoa that may cause disease in animals and occasionally in humans. Novel Piroplasmida clades and species have been found in wild animals from Brazil based on the phylogenetic ...

Harnessing 50 years of tick population genetics: Choosing the right molecular tool for contemporary research

Journal of Animal Ecology, Volume 94, Issue 11, Page 2159-2177, November 2025.
Population genetics reveals how ticks interact with hosts, microbiomes and environments. This review guides researchers in choosing the best tool for the job, weighing cost, resolution, reproducibility and throughput to study tick population structure. Abstract Ticks are ectoparasites of major medical, veterinary and ecological importance, transmitting

Host–parasite relationship in urban environments: A network analysis of haemoparasite infections in Nasua nasua Linnaeus (South American coati)

Medical and Veterinary Entomology, Volume 39, Issue 3, Page 456-463, September 2025.
Urban environments alter host–parasite dynamics, as seen in Nasua nasua, where haemotropic Mycoplasma plays a key role in parasite spread through frequent social interactions. Network analysis revealed low modularity in interactions between N. nasua and tick‐borne haemoparasites, with functional roles unaffected by biotic factors, tick infestation or ...

Deslocamento horizontal do carrapato amblyomma sculptum (acari: ixodidae): bases para a prevenção de picadas [PDF]

, 2023
For the prevention of diseases transmitted by ticks, it is essential to know their bioecology, especially their ability to move horizontally. This ability defines the range of the parasite from infested places to humans and can be important to define ...

The Immunology of Alpha‐Gal Syndrome: History, Tick Bites, IgE, and Delayed Anaphylaxis to Mammalian Meat

Immunological Reviews, Volume 332, Issue 1, July 2025.
ABSTRACT The primary features of the alpha‐gal syndrome (AGS) are (i) The IgE ab that are causally related to anaphylaxis with infusions of Cetuximab are specific for galactose alpha‐1,3‐galactose. (ii) In the USA, this IgE ab is induced by bites of the tick Amblyomma americanum. (iii) The anaphylactic reactions to food derived from non‐primate mammals

Is Zebrafish a Good Model for the Alpha‐Gal Syndrome?

The FASEB Journal, Volume 39, Issue 9, 15 May 2025.
ABSTRACT The alpha‐Gal syndrome (AGS) is an underdiagnosed tick‐borne allergy characterized by both immediate and delayed IgE‐mediated anaphylactic reactions to the galactose‐alpha‐1,3‐galactose (alpha‐Gal) epitope. Common manifestations include gastrointestinal, cutaneous, and respiratory symptoms appearing 2–6 h after the consumption of mammalian ...

Serpins in the Spotlight: Novel Bioinformatic Insights Into Hyalomma dromedarii Sialotranscriptome

Biochemistry Research International, Volume 2025, Issue 1, 2025.
Ticks pose a significant global threat to human and animal health as vectors of numerous pathogens, including bacteria, viruses, and parasites. Beyond their harmful impact, tick salivary glands contain serine protease inhibitors (serpins) known for their potential pharmaceutical properties.
