Risk factors, pathologies and control of gut-dwelling roundworms in chickens

Helminthologia
Nematode infections pose a threat to backyard chickens, presenting serious health and productivity challenges. The study aimed to assess risk factors related to pathological changes and the effect of mebendazole and its derivatives against nematode ...

Trait-mediated diversification in nematode predator–prey systems [PDF]

, 2011
Nematodes are presumably the most numerous Metazoans in terrestrial habitats. They are represented at all trophic levels and are known to respond to nutrient limitation, prey availability, and microbial resources.

Evidence for adaptive explanations of semelparity in animals

Biological Reviews, EarlyView.
ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

Nematode survival in relation to soil moisture [PDF]

, 1973
Established nematode populations are very persistent in the soil. It is known that they need sufficient soil moisture for movement, feeding and reproduction (fig. 5), and that there are adverse soil moisture conditions which they cannot survive.

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives

Biological Reviews, EarlyView.
ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.

Organoids in parasitology: a game-changer for studying host–nematode interactions

Parasitology
Gastrointestinal (GI) nematode infections represent a significant health burden globally, affecting both humans and livestock. Traditional in vitro models to study host–parasite interactions, such as immortalized cell lines, have limitations that hinder ...

Radiologic, Histologic and Scanning Electron Microscopic Characterization of the Peritoneal Reflection in Crohn's Disease

Clinical Anatomy, EarlyView.
ABSTRACT The peritoneal reflection bridges visceral and parietal peritoneum and lacks adjoining or underlying organs. As such it provides an opportunity to perform a focussed examination of the peritoneum in Crohn's disease. The aim of this study was to exploit this anatomical property and conduct a multilayered, focussed examination of the peritoneal ...

RNAseq Analysis of the Drosophila Response to the Entomopathogenic Nematode Steinernema

G3: Genes, Genomes, Genetics, 2017
Drosophila melanogaster is an outstanding model to study the molecular and functional basis of host–pathogen interactions. Currently, our knowledge of microbial infections in D.

Parascaris spp. induced surgical colic in juvenile horses—A Scandinavian perspective

Equine Veterinary Journal, EarlyView.
Abstract Background Parascaris spp. commonly infects foals, and high burdens can cause fatal small intestinal impactions. Progressive anthelmintic resistance poses a risk for an increase of Parascaris spp. related disease in juvenile horses. Objectives To investigate Parascaris‐related surgical intestinal lesions, with special emphasis on ascarid ...

Human case of gastric infection by a fourth larval stage of Pseudoterranova decipiens (Nematoda, Anisakidae)

Revista de Saúde Pública, 1997
Only three cases of human infection by anisakid nematodes have been reported in Chile since 1976. In the present case, an anisakid worm, identified as a fourth-stage Pseudoterranova decipiens larva, was removed with a gastroendoscopic biopsy clipper from
