Signatures of selection for resistance to Haemonchus contortus in sheep and goats

BMC Genomics, 2019
Gastrointestinal nematode infection (GNI) is the most important disease affecting the small ruminant industry in U.S. The environmental conditions in the southern United States are ideal for the survival of the most pathogenic gastrointestinal nematode ...

RIG-I has a role in immunity against Haemonchus contortus, a gastrointestinal parasite in Ovis aries- a novel report

bioRxiv, 2020
RIG-I is associated to the DExD/H box RNA Helicases. It is a Pattern Recognition Receptor (PRR), playing a crucial role in the system and is a germ line encoded host sensor to perceive Pathogen Associated Molecular Patterns or PAMPs.

Epidemiological study of genetic diversity and patterns of gene flow in Haemonchus species affecting domestic ruminants in Egypt

Bulletin of the National Research Centre, 2018
Background Haemonchosis is a major parasitic disease in Egyptian sheep industry and its effect on production, animal wellbeing, and welfare is likely to increase. The present study recorded Haemonchus spp.

Development of larvae of suborders Strongylata and Rhabditata in differently mineralized soils

Vìsnik Dnìpropetrovsʹkogo Unìversitetu: Serìâ Bìologìâ, Ekologìâ, 2008
Dependence of suborders Strongylata and Rhabditata larvae development from the mineralization level of soil has been established. With increase of concentration of salt the period of the larvae viability decreases.

Differences in immune responses to Haemonchus contortus infection in the susceptible Ile de France and the resistant Santa Ines sheep under different anthelmintic treatments regimens

Veterinary Research, 2019
Understanding the immunological basis of resistance to gastrointestinal nematode infections in livestock is important in order to develop novel methods of parasite control such as vaccination or genetic selection for parasite resistance.

Pomegranate extracts on larval inhibition of Haemonchus spp and Cooperia spp obtained from cattle

Bioscience Journal, 2016
Consumers increasingly demand natural food and absent of toxic waste and medicated. The aim of this study was to evaluate the aqueous extract of dried and in natura stem from pomegranate on the larval inhibition of Haemonchus spp.

Transcriptome analysis unraveled potential mechanisms of resistance to Haemonchus contortus infection in Merino sheep populations bred for parasite resistance

Veterinary Research, 2019
Haemonchus contortus is one of the most pathogenic gastrointestinal nematodes in small ruminants. To understand molecular mechanisms underlying host resistance to this parasite, we used RNA-sequencing technology to compare the transcriptomic response of ...

Anthelmintic resistance in sheep nematodes in Australia: a compilation of recent test results

Australian Veterinary Journal, EarlyView.
Objective The results of recent faecal egg count reduction tests (FECRTs) were collated to provide an indication of the prevalence and severity of anthelmintic resistance in sheep nematodes across Australia and of changes in comparison to earlier testing reports.

Potential of the Predatory Mites Gamasellodes lavafesii (Mesostigmata: Ascidae) and Cosmolaelaps mediocuspis (Mesostigmata: Laelapidae) on Different Soil Pests/Parasites and Alternative Prey for Large‐Scale Rearing

Journal of Applied Entomology, Volume 150, Issue 5, Page 562-572, June 2026.
ABSTRACT Many species of Mesostigmata soil mites have potential as biological control agents of pests/parasites. This study evaluated the predation potential of two of these species, Gamasellodes lavafesii (Ascidae) and Cosmolaelaps mediocuspis (Laelapidae).
