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)

open access: yesVeterinary 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.

FACTORS AFFECTING VARIABILITY OF RESISTANCE IN GAROLE SHEEP NATURALLY INFECTED WITH HAEMONCHUS CONTORTUS [PDF]

open access: yesExploratory Animal and Medical Research, 2013
Resistance status against natural infection to Haemonchus contortus as well as influence of season, sex, body weight, and haemoglobin type on resistance levels were evaluated in 309 numbers of Garole sheep.

Inhibited development in Haemonchus contortus

open access: yesParasitology, 1975
Inhibited development of Haemonchus contortus was studied in single experimental infections of worm-free lambs. Chilling of the infective larvae at + 4°C was without effect on the percentage of larvae subsequently becoming inhibited and a period of exposure to autumnal conditions was unnecessary to induce a high rate of inhibition.

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

open access: yesEcology 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.

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

open access: yes, 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

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

open access: yesParasite 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.

Genetic identification of gastrointestinal parasites in the world's most endangered ungulate, the hirola (Beatragus hunteri)

open access: yesVeterinary Record, Volume 196, Issue 12, 21/28 June 2025.
Abstract Background The hirola (Beatragus hunteri) is the world's most critically endangered antelope. Its parasitic fauna has never been genetically characterised, raising questions about its possible role in the species' population decline. This study aimed to assess the presence of gastrointestinal parasites in hirolas and their transmission ...
