The occurrence of resistance to three of commonly used anthelmintics, Pyrantel tartrate (Banminth), Albendazole2.5% (Valbazen) and Duramectin 1% (Dectomax) was studied in locally bred sheep in Kafr El Sheikh Governorate, Egypt, by means of faecal egg count reduction test (FECRT). The faecal egg count reduction test showed that Pyrantel tartrate and Albendazole were less than 95% effective, 77% and 89% FECR% value respectively (i.e.: presence of resistance) while Duramectin showed full efficacy, 100% FECR% value. Culture of faecal samples before and after treatment in groups was done to interpret the anthelmintic resistance of individual nematode species. Where Ostertagia circumcincta and Bunostomum trigonocephalumn were susceptible to Pyrantel tartrate and Albendazole (100% FECR for each) but Nematodirus battus and Homonchus contortus have developed varying degrees of resistance for both drugs (56.3%, 48.2% and 88%, 70% respectively). Meanwhile, all nematode species were susceptible to Duramectin.

UI	MeSH Term	Description	Entries
D007559	Ivermectin	A mixture of mostly avermectin H2B1a (RN 71827-03-7) with some avermectin H2B1b (RN 70209-81-3), which are macrolides from STREPTOMYCES avermitilis. It binds glutamate-gated chloride channel to cause increased permeability and hyperpolarization of nerve and muscle cells. It also interacts with other CHLORIDE CHANNELS. It is a broad spectrum antiparasitic that is active against microfilariae of ONCHOCERCA VOLVULUS but not the adult form.	Eqvalan,Ivomec,MK-933,Mectizan,Stromectol,MK 933,MK933
D009349	Nematode Infections	Infections by nematodes, general or unspecified.	Infections, Nematode,Infection, Nematode,Nematode Infection
D011715	Pyrantel	A depolarizing neuromuscular-blocking agent, that causes persistent nicotinic activation resulting in spastic paralysis of susceptible nematodes. It is a drug of second-choice after benzimidazoles for treatment of ascariasis, hookworm, and pinworm infections, being effective after a single dose. (From Smith and Reynard, Textbook of Pharmacology, 1992, p920)
D004351	Drug Resistance	Diminished or failed response of an organism, disease or tissue to the intended effectiveness of a chemical or drug. It should be differentiated from DRUG TOLERANCE which is the progressive diminution of the susceptibility of a human or animal to the effects of a drug, as a result of continued administration.

Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
