A questionnaire survey of nematode parasite control practices on goat farms in Denmark
(University of Nairobi., 1996)
A questionnaire survey to examine worm control practices on angora and other goat farms in Denmark was undertaken in 1993. Questionnaires were inserted in the July, 1993 issue of the official journal of the angora goat ...
Resistance to thiabendazole, febantel albendazole and levamisole in gastrointestinal nematodes of goats in Kenya
(University of Nairobi., 1993-03)
A survey was undertaken to determine resistance to thiabendazole (TBZ), febantel (FB), albendazole (ALB) and levamisole (LVM) in gastrointestinal nematodes of goats on 4 farms in Kenya. Resistance was first investigated ...
Worm control practices on sheep farms in Nyandarua District of Kenya
(1997)
A questionnaire investigation was used to examine anthelmintic usage and practical worm control for sheep on 50 farms selected randomly in Nyandarua District of Central Kenya. Control of helminths was based primarily on ...
A survey of anthelmintic resistance in nematode parasites of goats in Denmark.
(1996)
The occurrence of anthelmintic resistance in 15 goat herds in Denmark was investigated using the faecal egg count reduction test (FECRT), egg hatch assay (EHA) for thiabendazole (TBZ) and a microlarval development assay ...
Worm control practices on sheep farms in Denmark and implications for the development of anthelmintic resistance
(1996)

Haemonchus And Trichostrongylus Species In Goats In Kenya Resistant To Anthelmintics
(University of Nairobi, 1993)
The relationship between faecal egg count reduction and the lethal dose 50% in the egg hatch assay and larval development assay.
(1998-06)
The relationship between resistance detected in the faecal egg count reduction test (FECRT) and the lethal dose 50%(LD50) in the egg hatch assay (EHA) for benzimidazoles (BZs) and a larval development assay (LDA) for BZs, ...
Observations On Changes In Resistance To Levamisole In Haemonchus Contortus After Passage In Sheep And Calves
(University of Nairobi, 1991)
Effect of selection pressure for thiabendazole resistance on fitness of Haemonchus contortus in sheep
(1990-04)
A strain of Haemonchus contortus showing moderate levels of resistance to thiabendazole (TBZ) (egg hatch assay LC50 2.1 microM) was subjected, in alternating sequence, to 5 in vitro and 4 in vivo selections with TBZ. This ...
