Genomic Analysis of Hair Sheep From West/Central Africa Reveals Unique Genetic Diversity and Ancestral Links to Breed Formation in the Caribbean

Molecular Ecology, Volume 34, Issue 24, December 2025.
ABSTRACT Cameroon Blackbelly sheep are a domestic breed of hair sheep from West/Central Africa. They are popular with small‐holder farmers in Cameroon as they are highly resilient to local environmental challenges and are prolific a‐seasonal breeders.

In Vitro Study on the Efficacy of Ziziphus vulgaris L. and Camellia sinensis (L.) Kuntze Extracts for Controlling Varroa destructor (Acari: Varroidae) in Apis mellifera (Hym.: Apidae)

Veterinary Medicine and Science, Volume 11, Issue 5, September 2025.
Extracts of Ziziphus vulgaris and Camellia sinensis applied in wooden cages increase Varroa destructor mortality (5–25 µL/L air) while minimizing Apis mellifera harm, offering a sustainable mite control method. ABSTRACT Background Ziziphus vulgaris L.

The emergence of resistance to the benzimidazole anthlemintics in parasitic nematodes of livestock is characterised by multiple independent hard and soft selective sweeps [PDF]

, 2015
Anthelmintic resistance is a major problem for the control of parasitic nematodes of livestock and of growing concern for human parasite control. However, there is little understanding of how resistance arises and spreads or of the “genetic signature” of

Master of Puppets: How Microbiota Drive the Nematoda Ecology and Evolution?

Ecology and Evolution, Volume 15, Issue 8, August 2025.
The nematode microbiota can influence life‐history traits, thereby shaping the species' ecology and evolutionary trajectories. ABSTRACT In recent decades, the microbiota has emerged as a key driver of biological functions in metazoans, and nematodes are no exception.

Collagen processing and cuticle formation is catalysed by the astacin metalloprotease DPY-31 in free-living and parasitic nematodes [PDF]

, 2010
The exoskeleton or cuticle performs many key roles in the development and survival of all nematodes. This structure is predominantly collagenous in nature and requires numerous enzymes to properly fold, modify, process and cross-link these essential ...

Allotype‐Dependent Responses to the Vaccine Candidate Thrombospondin‐Like Protein of Dictyocaulus viviparus in Calves

Parasite Immunology, Volume 47, Issue 7, July 2025.
ABSTRACT The nematode Dictyocaulus viviparus causes parasitic bronchitis in cattle. There is a vaccine based on irradiated larvae against this parasite. However, no memory response is induced, and donor calves are needed for culturing the larvae. Therefore, a well‐defined subunit vaccine would be welcomed.
