Haemonchus populations were collected from cattle from mid-western and eastern Southern US (four and six populations, respectively) to determine the relative prevalence of Haemonchus contortus and Haemonchus placei and the frequency of the three isotype-1 β-tubulin polymorphisms associated with benzimidazole resistance. A minimum of 32 individual adult worms were genotyped at position 24 of the...

We describe a case of anthelmintic resistance on one of the largest organic small ruminant farms in Denmark. The flock was established in 2007 by purchase of animals from other Danish farms and had history of clinical parasitism, high mortality of young stock and anthelmintic treatment failure. In October 2011, 40 lambs and 40 kids were selected for a faecal egg count reduction test (FECRT) wit...

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...

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 spic-ules and molecular characters. two hundre...

background: cross antigenicity is the major problem in developing a reliable tool for immunodiagnosis and immunoprophylaxis of parasitic diseases. mixed infection due to different types of gastrointestinal parasites is more common than single species infection under field condition. methods: the present study was undertaken to detect antigenic cross-reactivity among haemonchus contortus, oesoph...

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...

Resistance to eprinomectin was suspected in a dairy sheep farm southwestern France. The efficacy of topical and injection formulations against gastrointestinal nematodes (GINs) compared using faecal egg count reduction test. GIN species were identified by real-time PCR, concentrations measured serum High-Performance Liquid Chromatography 2 5 days after treatment. Efficacies 99.6% 86.1% for form...

The complete coding sequence of Haemonchus (H.) contortus HC29 cDNA was generated by rapid amplification of cDNA ends in combination with PCR using primers targeting the 5'- and 3'-ends of the partial mRNA sequence. The cloned HC29 cDNA was shown to be 1,113 bp in size with an open reading frame of 507 bp, encoding a protein of 168 amino acid with a calculated molecular mass of 18.9 kDa. Amino ...

HIGHLIGHTS First report of phylogeny and haplotype diversity Haemonchus contortus isolated from Gaddi (breed) goats North India. The occurrence different haplotypes evinced presence indels at distinct places. There was probable establishment heterozygosity in putative hybrid H. worms.
