The anthelmintic effect of Bacillus thuringiensis Cry5B on Haemonchus contortus in sheep
… days after treatment, and at necropsy the female worm burden was significantly reduced by 98%. In the second experiment inactivated, asporogenous Bt expressing cytosolic Cry5B (IBaCC) was used. Treated animals received 60mg/kg Cry5B, administered daily for three days. By 72 hours after the first …

Haemonchus contortus Infections in Alpacas and Sheep
… exposure to H. contortus. All animals were dewormed orally with a cocktail of fenbendazole, levamisole, and ivermectin. Haemonchus contortus infective larvae were administered orally to alpacas and rams in the following groups:1) 20,000 larvae as a single dose (bolus, n=6 both alpacas and …

Effects of Dietary Immunomodulation on Parasite Load in Commercial Crossbred Lambs
… with CelmanaxRTM did not have any effects on worm burden or fecal egg count (FEC) in infected lambs. These results indicate that CelmanaxRTM has immunomodulatory properties, but may not have absolute effects on clearing helminth infections in Texel crossbred lambs.

A comparative study of gastrointenstinal nematode infection in traditional and commercial chickens and efforts of anthelminthic treatment on production
… r^= 0.61) between the weight gain and the worm burden in the untreated control group and a weak negative correlation (r =-0.261, r^ 0.07) between the weight gain and the worm burden in the treated experimental group. It was noted that anthehnintic treatment of young birds would improve the …

Endoparasites of working donkeys in Ethiopia: epidemiological study and mathematical modelling
… anthelmintic treatment on the adult cyathostomin worm burden have shown that treating donkeys only once in a year or a combination of once in a year followed by every two or even four years can substantially reduces and maintains the parasite burden far below the pre-treatment level for many …

Concurrent Infection of TRYPANOSOMA MUSCULI Kendell, 1906, and SCHISTOSOMA MANSONI Sambon, 1907 in Mice
… or morphology of the <em>S. mansoni</em> worms as tested in this study. Although ablastin inhibits glycolytic pathway enzymes in young trypanosomes, it does not seem to affect those of the blood fluke. Effects of schistosome membrane function must also be ruled out as no reduction in worm …

Investigations into the use of continuous low-level medication for the control of helminths in the ruminant
… required to inhibit egg hatch and eliminate the worm burden is established. A minimum daily release rate of 3.0 mg per kg bodyweight was shown to be required to completely inhibit egg hatch and 4.5 mg per kg for effective vermicidal activity. In similar experiments, the anthelmintic activities of …

Host and Seasonal Effects on the Infection Dynamics of Skrjabinoptera Phrynosoma (Ortlepp) Schulz, 1927, a Parasitic Nematode of Horned Lizards
… per host, length of those nematodes, and total worm burden (ΣL)) were analyzed within three collection periods during the active season of 2008. Number and length of nematodes of different sex categories also was analyzed within collection period and across season. The relationship between …

Trichuris Muris Whey Acidic Protein Induces Type 2 Protective Immunity Against Whipworm
<p>Human whipworm (<em>Trichuris trichiura</em>) infects approximately 1 in 15 people worldwide, representing the leading infectious cause of colitis and subsequent, inflammatory bowel disease (IBD). Current control measures focused on mass deworming have had limited success due to low drug …

The role of Cysteinyl leukotriene receptor-1 during experimental helminth infections in murine model

Immunological evaluation of DNA vaccines against Haemonchus contortus and Toxoplasma gondii in sheep
… were taken and all sheep were slaughtered for worm burden determination at the end of the trial. Vaccination with pSecTag2-15 tended to reduce the mean FEC (by 58%) and mean adult worm burdens (by 65%) compared with the PBS controls. Significantly higher levels of ES-specific IgA and IgG2 were …

Physicochemical, biological and β-haematin inhibiting activity of pyrido-dibemequines, pyrido[1,2-α]benzimidazoles and their derivatives

Software-based decision-support : a basis for the development of a predictive system for sustainable management of haemonchosis in small ruminants
