The prevalence of Helminth parasites in the gastro-intestinal tract of wild African sharptooth catfish Clarias gariepinus (Siluriformes: Clariidae) in Gwagwalada, Nigeria

open access: yesCuadernos de investigación UNED, 2013
A study on the gastro-intestinal helminth parasites of wild C. gariepinus was carried out in Gwagwalada Area Council of FCT, Abuja, Nigeria. A total of 110 samples were examined which includes 42 males and 68 females.

Integrating infection intensity and aggregation into the dynamics of pathogens with within‐host replication

open access: yesJournal of Animal Ecology, EarlyView.
We bridge micro‐ and macroparasite theory with a model tracking pathogen load heterogeneity. By incorporating load‐dependent mortality and within‐host pathogen growth, we show how pathogen load aggregation alters disease prevalence, host suppression effects, and virulence evolution, providing insights for managing complex infectious disease like ...

[Proteases in helminthic parasites].

open access: yesVeterinary research, 2000
Proteases catalyse the cleavage of internal peptide bonds within peptides and proteins. They are classified into four major classes and are involved in a broad range of eukaryotic processes. Proteases have also been found to play a number of critical roles in the virulence of pathogenic agents, particularly of nematode parasites.

Putting Rodents at the Center of One Health Programs: A Narrative Synthesis

open access: yesIntegrative Zoology, EarlyView.
Rodents link human, animal, and environmental health across diverse ecosystems. Rodent diversity underpins both zoonotic disease risk and ecosystem function. Environmental change reshapes rodent communities and spillover dynamics. Rodents act as reservoirs, amplifiers, and sentinels of emerging pathogens.

Drivers of Host–Pathogen Community Assemblages in European Forests and Urban Green Spaces

open access: yesIntegrative Zoology, EarlyView.
ABSTRACT Despite advances in understanding infectious diseases, the persistence and re‐emergence of wildlife pathogens continue to raise public and veterinary health concerns. This study investigates the relationship between biodiversity and rodent‐borne diseases in Europe, focusing on habitat alterations and their impact on rodent diversity.

Biotic Interrelationships of Helminth Parasitism

open access: yesPublic Health Reports (1896-1970), 1951
Biotic interrelationships in Alaska have so far suffered little from man's attempts to improve upon nature. As a result of these favorable circumstances, biological investigation in Alaska offers unusual opportunity for elucidating problems which can no longer be approached in the more populated parts of North America. One is very fortunate to have the

Helminth infections in domestic dogs from Russia [PDF]

open access: yesVeterinary World, 2016
Dogs are the hosts for a wide helminth spectrum including tapeworms, flatworms, and nematodes. These parasites affect the dog health and cause morbidity and mortality, especially in young and old animals.

Basophils in Immunity: Activation Pathways, Roles in Allergy and AllergoOncology and Application of the Basophil Activation Test

open access: yesAllergy, EarlyView.
ABSTRACT Basophils, the least abundant leukocytes, are increasingly recognised as potent immunomodulators. Upon activation, they rapidly release preformed granule‐associated mediators including histamine and lipid mediators such as LTC4, while cytokine production occurs over a longer timescale, contributing to downstream immune responses.
