Evolution of Ivermectin Resistance in the Nematode Model Caenorhabditis elegans: Critical Influence of Population Size and Altered Emodepside Efficacy

Evolutionary Applications, Volume 19, Issue 4, April 2026.
ABSTRACT The emergence and spread of anthelmintic resistance represent a major challenge for treating parasitic nematodes, threatening mass‐drug administration control programs in humans and zoonotic hosts. Currently, experimental evidence to understand the influence of management (e.g., treatment dose and frequency) and parasite‐associated factors (e ...

The Relationship Between Immunopathology and Body Condition of Mixed‐Age Ewes

New Zealand Journal of Agricultural Research, Volume 69, Issue 1, February 2026.
Ill thrift in ewes, characterised by less than desirable body condition, is a multifactorial condition often attributed to nutritional deficits, though immunopathological factors may also play a role. This study investigated associations between body condition scores (BCS) and immunopathological states in 120 mixed‐age ewes grazing pasture over 4 ...

Body condition score and weight are effective targeted selective treatment indicators for gastrointestinal nematodes in premating ewes

Veterinary Record, Volume 198, Issue 3, Page e85-e91, 31 January/7 February 2026.
Abstract Background Ewe reproductive performance is key for flock profitability but can be impacted upon by gastrointestinal nematode (GIN) infections. Farmers commonly deworm ewes pre‐mating, yet concerns regarding anthelmintic resistance increase pressure to reduce wormer use.

Identification of β‐galactosidases along the secretory pathway of Nicotiana benthamiana that collectively hamper engineering of galactose‐extended glycans on recombinant glycoproteins

Plant Biotechnology Journal, Volume 24, Issue 1, Page 224-238, January 2026.
Summary Glycosylation is an important aspect for many biopharmaceuticals, including vaccines against parasitic helminths. Plants, especially Nicotiana benthamiana, have proven to be excellent production hosts for biopharmaceuticals with tailor‐made glycosylation.

Regional heterogeneity and unexpectedly high abundance of Cooperia punctata in beef cattle at a northern latitude revealed by ITS-2 rDNA nemabiome metabarcoding

Parasites & Vectors, 2022
Background The species composition of cattle gastrointestinal nematode (GIN) communities can vary greatly between regions. Despite this, there is remarkably little large-scale surveillance data for cattle GIN species which is due, at least in part, to a ...

Antiparasitic Potential of Bioactive Compounds From Punica granatum: Preventive and Therapeutic Effects

Journal of Parasitology Research, Volume 2026, Issue 1, 2026.
Diseases caused by parasites are a global public health problem. Due to their heterogeneity and diversity, they can affect various hosts, and some diseases are considered zoonotic. Therapeutic control in parasitic diseases has lost its effectiveness over the last decades.
