The current research is the investigation of an ethnopharmacological impact i.e., anthelmintic action of fruits of three traditionally used trees, i.e. Pterospermum acerifolium Linn. Diospyros malabarica Kostel and Putranjiva roxburghii Wall. The crude extracts of fruits were obtained in polar and non-polar solvents i.e., petroleum ether, chloroform, methanol and water and evaluated for their i...

Sixty-five sheep farms in the northern provinces of Buenos Aires, Entre Rios, Corrientes, Cordoba and Sante Fe were used in this survey on anthelmintic resistance. Anthelmintic groups tested were the benzimidazoles, levamisole, the combination levamisole + benzimidazole product and the avermectins. The overall level of resistance was 46% of properties, with resistance to the individual drug gro...

BACKGROUND Resistance against benzimidazoles (BZ) has recently been detected in Norwegian sheep flocks through a large scale prevalence survey based on the faecal egg count reduction test (FECRT). The use of this test in combination with bulk larval culture only gives an indication of which gastrointestinal nematodes genera that are involved and these results have to be confirmed by a controlle...

El objetivo de este estudio fue evaluar tres pastos forrajeros, Bromus diandrus, Oplismenus burmannii y Heteropogon contortus, las subfamilias Pooideae, Pooideae Panicoideae, respectivamente. Las principales variables respuesta, todas en base seca fueron: cenizas (Cen), proteína cruda (PC), extracto etéreo (EE), carbohidratos solubles (CS), fibra detergente neutro (FDN), contenido celular (CC =...

BACKGROUND Gastrointestinal nematode (GIN) remains the most important pathogenic constraint of small ruminant production worldwide. The improvement of the host immune response against GIN though breeding for improved animal resistance, vaccination and nutritional supplementation appear as very promising methods. The objective of this study was to investigate the effect of four nutritional statu...

Haemonchus contortus (H. contortus) is one of the most important parasites of small ruminants, especially goats and sheep. The complex life cycle of this nematode is a main obstacle for the control and prevention of haemonchosis. So far, a special form of arrested development called diapause different from the dauer stage in Caenorhabditis elegans (C. elegans) has been found in many parasitic n...

Gastrointestinal nematode (GIN) infections have an important negative impact on small ruminant production. The selection of genotypes resistant to these parasitic infections is a promising alternative control strategy. Thus, resistance against GIN is an important component of small ruminant breeding schemes, based on phenotypic measurements of resistance in immune mature infected animals. In th...

The exoskeleton or cuticle performs many key roles in the development and survival of all nematodes. This structure is predominantly collagenous in nature and requires numerous enzymes to properly fold, modify, process and cross-link these essential structural proteins. The cuticle structure and its collagen components are conserved throughout the nematode phylum but differ from the collagenous...

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...
