Article Synopsis
- The domestication process has been extensively studied, beginning with Belyaev's experiment on silver foxes, which showed that selecting for tameness disrupts systems controlling development, leading to typical domestication traits.
- Additional hypotheses, like the thyroid rhythm and neural crest cell hypotheses, have been proposed, but the recent parasite-mediated domestication hypothesis (PMD) suggests that endoparasites may play a critical role in this process.
- Research comparing parasite loads in wild boars and domestic pigs from Slovenia and Croatia found different parasite taxa in both populations, providing a basis to explore how parasite susceptibility may have contributed to domestication.
Article Synopsis
- In a study of 428 foxes, researchers found that 93.2% had intestinal parasites, using a washing-out method to analyze the samples.
- The most common nematodes identified were Uncinaria stenocephala, Toxocara canis, and Molineus patens, while notable cestodes included Mesocestoides sp. and Taenia crassiceps.
- This research is the first comprehensive examination of intestinal parasites in red foxes in Slovenia, with a previous report indicating a 2.6% prevalence of Echinococcus multilocularis in the same population.
The ability to reliably detect anthelmintic resistance is a crucial part of resistance management. If data between countries are to be compared, the same test should give the same results in each laboratory. As the egg hatch test for benzimidazole resistance is used for both research and surveys, the ability of different laboratories to obtain similar results was studied through testing of known isolates of cyathostomins, Haemonchus contortus, Ostertagia ostertagi, and Cooperia oncophora in programs supported by the EU (Cost B16 and FP6-PARASOL).

We have used this technology for the differentiation of the closely related cyathostomin species Cylicocyclus elongatus and C. insigne from the horse.

The molecular analysis of 100 adults recovered from an anthelmintic-naïve horse revealed 80% homozygous TTC/TTC individuals, 17% heterozygous TTC/TAC and 3% homozygous TAC/TAC. A naturally infected horse was treated with increasing fenbendazole (FBZ) dosages to select a BZ-resistant population of cyathostomes.
