Zoonotic Disease Transmission May Be Linked to Host Co‐Occurrence Network Topology

Annals of the New York Academy of Sciences, Volume 1554, Issue 1, Page 110-120, December 2025.
A global analysis of zoonotic host co‐occurrence networks identified 22 networks from five continents (A) and 87 hosts from 16 orders of mostly birds but also mammals (B) as having a high potential for disease transmission. ABSTRACT Most human pathogens are zoonotic, transmitted from vertebrate hosts to humans.

Global trend of food‐induced anaphylaxis: Up to date

Pediatric Allergy and Immunology, Volume 36, Issue 12, December 2025.
Abstract This review examines the evolving global landscape of food‐induced anaphylaxis (FIA), revealing critical epidemiological shifts that challenge traditional allergen management paradigms. As the leading cause of anaphylaxis worldwide, FIA demonstrates striking geographic, age‐specific, and temporal patterns that reflect broader changes in ...

Is the distribution of Amblyomma variegatum influenced by interspecific competition with Amblyomma hebraeum? Preliminary study: distribution range in Mozambique [PDF]

, 2012
Widely spread in intertropical and subtropical areas of Africa, the southern distribution of Amblyomma variegatum in Mozambique seems to have its limit around the Save River, at the 22nd parallel South. This area also corresponds to the northern limit of

Molecular Confirmation of Rickettsia parkeri in Amblyomma ovale Ticks, Veracruz, Mexico

Emerging Infectious Diseases, 2019
We found Rickettsia parkeri in Amblyomma ovale ticks collected in Veracruz, Mexico, in 2018. We sequenced gene segments of gltA, htrA, sca0, and sca5; phylogenetic reconstruction revealed near-complete identity with R. parkeri strain Atlantic Rainforest.

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

Neuronal in vitro impact of Amblyommaamericanumsalivary glands extracts [PDF]

, 2018
When a tick feeds off a host, the salivary glands of the tick excrete saliva to assist the tick in feeding (1). The reason saliva assists the tick in consuming its blood meal is due to its immunosuppressive, anti-inflammatory, and anti-coagulant ...
