Antiparasitic activity of chicory (Cichorium intybus) and its natural bioactive compounds in livestock: a review [PDF]

, 2018
Increasing drug resistance in gastrointestinal (GI) parasites of livestock and concerns about chemical residues in animal products and the environment are driving the development of alternative control strategies that are less reliant on the use of ...

Experimental Evidence That Blood Parasite Infection Affects Incubation Patterns in a Cavity‐Nesting Songbird

Integrative Zoology, EarlyView.
Chronic blood parasite infections in wild birds can affect their incubation behavior. In pied flycatchers, females with reduced parasite infections incubated for longer than control females. Despite behavioral changes, no immediate effects on fitness were observed.

Predicting the risk and speed of drug resistance emerging in soil-transmitted helminths during preventive chemotherapy

Nature Communications
Control of soil-transmitted helminths relies heavily on regular large-scale deworming of high-risk groups (e.g., children) with benzimidazole derivatives.

Immunomodulation by Helminths: Intracellular Pathways and Extracellular Vesicles

Frontiers in Immunology, 2018
Helminth parasites are masters at manipulating host immune responses, using an array of sophisticated mechanisms. One of the major mechanisms enabling helminths to establish chronic infections is the targeting of pattern recognition receptors (PRRs ...

A contemporary map of Fasciola hepatica distribution in sheep and cattle in New South Wales

Australian Veterinary Journal, EarlyView.
Fasciola hepatica is a global threat to livestock production, human health, and food security. Infection causes significant reductions in milk production and quality, feed conversion efficiency, wool quality, and reproductive performance. In New South Wales (NSW), Australia, data on the distribution of F. hepatica are more than 50 years out of date and

Homo sapiens, industrialisation and the environmental mismatch hypothesis

Biological Reviews, EarlyView.
ABSTRACT For the vast majority of the evolutionary history of Homo sapiens, a range of natural environments defined the parameters within which selection shaped human biology. Although human‐induced alterations to the terrestrial biosphere have been evident for over 10,000 years, the pace and scale of change has accelerated dramatically since the onset

A cosmopolitan parasite of Rattus in the Galápagos rodents raises conservation concerns

Conservation Science and Practice, EarlyView.
We draw attention to a recent study that identified the invasive nematode Mastophorus muris, typically associated with Rattus, infecting two endemic Galápagos rats on islands where no invasive rodents have been previously recorded. This unexpected finding raises concerns about undetected rodent introductions and highlights the urgent need for ...
