Control of nematode parasites with agents acting on neuro-musculature systems: lessons for neuropeptide ligand discovery.
- BiologyAdvances in experimental medicine and biology
The properties of existing agents that have been used to control nematode parasites and that have an action on neuromuscular systems are commented on and some warning signs for recognized but dangerous obstacles are provided.
Update on Parasite Control in Slllall Rulllinants 2006 Addressing the Challenges Posed by Multiple-Drug Resistant
Unless veterinarians take an active and leading role in the education of small ruminant owners and help to implement these new approaches to parasite control, there may be no effective anthelmintics remaining when control fails, and any new technologies or developments in non-chemical GIN control methods will be less effective than chemical control.
Anthelmintic resistance in nematodes of horses.
- Biology, MedicineVeterinary research
The increasingly high prevalence of anthelmintic-resistant cyathostomes must be taken into account when designing worm control programs for horses, and strategies to decelerate further selection for drug resistance thereby extending the lifetime of currently effective anthel mintics should be implemented whenever possible.

Principles for the use of macrocyclic lactones to minimise selection for resistance
Objective To provide principles for the appropriate use of avermectin/milbemycin or macrocyclic lactone (ML) anthelmintics in sheep, to ensure effective worm control and to minimise selection for ML…

Total Anthelmintic Failure to Control Nematode Parasites of Small Ruminants on Government Breeding Farms in Sabah, East Malaysia
- Biology, MedicineVeterinary Research Communications
Tests for anthelmintic efficacy using the faecal egg count reduction test (FECRT) on the range of drugs used to control nematode parasites showed a total failure of the benzimidazole, imidothiazole, macrocyclic lactone and salicylanilide groups of anthel mintics to control H. contortus infections of sheep and goats on all farms.
Evaluation of prevalence and clinical implications of anthelmintic resistance in gastrointestinal nematodes in goats.
- Biology, MedicineJournal of the American Veterinary Medical Association
Anthelmintic resistance in GINs of goats is highly prevalent in the southern United States and emphasizes the need for reexamination of nematode control practices.

Control of gastrointestinal (GIN) parasites is of primary concern in any small ruminant health management program, and is critical to profitability of the farm. For many years, GIN were controlled by…
Kinetic disposition of albendazole in goats subclinically infected with gastrointestinal nematodes vis-à-vis naive animals following oral and intraruminal administration
- Medicine, BiologyJournal of Helminthology
As the duration of exposure of parasites to the toxic concentration of the anthelmintically active metabolite was prolonged, it could be assumed that intraruminal delivery of the drug would improve the efficacy of albendazole in parasitized goats.

Anthelmintic resistance in Australian sheep nematode populations.

The resistance status of gastro-intestinal nematodes to anthelmintics was evaluated on 881 sheep farms throughout Australia during 1991-92. Resistance was shown to be widespread. Overall, 85% of…
Resistance to synthetic pyrethroid pour-on insecticides in strains of the sheep body louse Bovicola (Damalinia) ovis.

The pour-on SP treatments significantly reduced the lice population but failed to eliminate the infestation in 7 of 13 experiments in sheep carrying strains of lice with resistance factors of greater than 4 to at least one of the SP compounds.
The pharmacodynamics of ivermectin in sheep and cattle.
- Biology, MedicineJournal of veterinary pharmacology and therapeutics
It is hypothesized that the low efficacy of ivermectin against small intestinal nematode compared with abomasal nematodes is not due to differences in iverMectin concentrations in the predilection sites but is probably due to tachyphylaxis in the nematODE allowing the small intestinal Nematodes to re-establish before they have left theirpredilection site.
A survey of organophosphate susceptibility in populations of Bovicola ovis (Schrank) (Phthiraptera, Trichodectidae)
A toxicological survey of field populations of the sheep body louse identified only one strain whose response to diazinon was recognisably separate from the normally distributed responses of the other strains, suggesting that a pyrethroid or propetamphos treatment would be the most appropriate control option.
