background: in order to deworm the ruminants especially of sheep in iran, consumption of benzimi­dazoles has more than 2 decades history and today farmers are using imidazothiazoles, macrocyclic lactones and mostly benzimidazole compounds (bzs) to treat infected farm animals. it has been demonstrated that the most common molecular mechanism leading to bzsresistance in haemonchus contortus is a ...

indirect plate enzyme-linked immunosorbent assay was standardized and evaluated for its effectivenessin immunodiagnosis of haemonchosis in experimental and clinical cases in sheep by using somatic wholeadult antigen of h. contortus. plate elisa was standardized using 5 μg/well antigen concentration with1:100 and 1:1000 of sera and conjugate dilution. indirect plate elisa was able to demonstrate...

BACKGROUND Haemonchosis has a negative effect on the farming industry throughout the world, especially in the tropic and sub-tropic countries. The present study was carried out to differentiate Haemonchus species from its main hosts in Iran, including sheep, goat and camel. METHODS The identification took place based on the morphometrics of the spicules and molecular characters. Two hundred s...

This study aimed to identify putative quantitative trait loci (QTL) that significantly affect internal parasite resistance in a backcross sheep population. A Romney x Merino backcross (to Merino) flock was challenged in 3 separate infections with Trichostrongylus colubriformis (primary and secondary) and Haemonchus contortus (tertiary). Haematological parameters were measured and faecal worm eg...

VANWYK, J.A. 1999. A comparison of the infectivity of cryopreserved versus unfrozen infective larvae of Haemonchus contortus, Trichostrongylus colubriformis and Trichostrongylus axei: Results of the Onderstepoort Veterinary Institute from 1977 to the present. Onderstepoort Journal of Veterinary Research , 66:285289 The infectivity for sheep of cryopreserved infective larvae (L3) of various stra...

Background. Haemonchosis caused by Haemonchus contortus is a predominant, highly pathogenic, and economically important disease of sheep and goats. Objective. Assessing the prevalence of Haemonchus parasite and its associated risk factors in sheep slaughtered at different restaurants of Wukro. Methods. Cross-sectional study using random sampling from November 2013 to April 2014 in a total of 38...

b ackground: due to the lack of a suitable and economic test for the analysis of the polymorphism at codon 167, we developed a new pcr-rflp technique, based on a modified forward primer (ut- hc167 mf-primer), to identify simultaneously the snps at codons 167 and 200 of isotype 1 β-tubu- lin gene of haemonchus contortus . m ethods: there already are several safe and easy methods for identificati...

This study was conducted to determine the effect of temperature and moisture stress on exsheathment process and infectivity of the infective larvae of the parasitic nematode Haemonchus contortus. Laboratory conditions were used in which infective (L3) of H. contortus were either subjected to gradually increasing temperatures, decreasing moisture or both. Post stress viability and exsheatment of...

This study was conducted to determine the molecular prevalence and characterization of Haemonchus contortus from sheep along with the benzimidazole (BZ) resistance in H. contortus populations. Fecal samples were collected from a total of 300 sheep in research area and analyzed by fecal flotation. qPCR assays were utilized on trichostrongylid egg positive samples in order to identify H. contortu...

Penelitian ini bertujuan Untuk mengidentifikasi efektivitas dan level penggunaan ekstrak daun kersen (Muntingia calabura) terhadap mortalitas cacing Haemonchus contortus secara in vitro. Desain penelitian menggunakan eksperimen vitro Rancangan Acak Lengkap (RAL). dirancang dalam 6 perlakuan, dimana setiap perlakuan diulang 4 kali ulangan terdiri dari 5 ekor betina sehingga terdapat 24 unit perc...
