Shining a Light on Haemonchus contortus in Sheep [PDF]

The Third International Tropical Agriculture Conference (TROPAG 2019), 2020
Heavy infestations of the Barber’s pole worm, Haemonchus contortus, can cause severe wasting, morbidity and mortality in animals if not promptly treated. The current detection methods for this blood-sucking parasite involve faecal worm egg counts and diagnosis of anaemia, both of which are time consuming and require expertise.

Haemonchus contortus-Sheep relationship: A review.

Revista Científica, 2007
La hemoncosis, causada por el nematodo del abomaso de rumiantes Haemonchus contortus, constituye una de las enfermedades parasitarias más notables del ganado ovino en todo el mundo. Las infecciones provocan síndromes anémicos y de mala digestión/absorción que pueden causar la muerte en los casos agudos y disminución de la producción en las formas ...

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).

FEC Check: Development of a decision support tool to aid interpretation of gastrointestinal nematode faecal egg counts in sheep

Veterinary Record, Volume 198, Issue 9, Page e373-e384, 2/9 May 2026.
Abstract Background Gastrointestinal nematode infections are ubiquitous in grazing livestock worldwide impacting animal health and production. Faecal egg count (FEC) is an accessible diagnostic test that can guide the need for treatment. However, interpretation of FECs can be challenging.
