BACKGROUND The single-dose benzimidazoles used against Trichuris trichiura infections in humans are not satisfactory. Likewise, the benzimidazole, fenbendazole, has varied efficacy against Trichuris suis whereas Oesophagostomum dentatum is highly sensitive to the drug. The reasons for low treatment efficacy of Trichuris spp. infections are not known. METHODOLOGY We studied the effect of fenbe...

Rhoads, M. L., Fetterer, R. H., Hill, D. E., and Urban, J. F., Jr. 2000. Trichuris suis: A secretory chymotrypsin/elastase inhibitor with potential as an immunomodulator. Experimental Parasitology 95, 36– 44. A serine protease inhibitor, termed TsCEI, was purified from adultstage Trichuris suis by acid precipitation, affinity chromatography (elastase–agarose), and reverse-phase HPLC. The molecu...

We previously analysed clinical and immunological parameters under Trichuris suis ova (TSO) therapy in four patients with secondary progressive multiple sclerosis. The serum Brain-derived neurotrophic factor (BDNF) levels of these four patients were assessed before, during and after therapy with TSO and showed significant decrease of BDNF during TSO therapy (p < 0.05).

The prevalence of helminthiasis was found to be 15.2 % in buffaloes. Out of 500 samples examined, 9.2 % and 5.4 % were infected with nematodes and trematodes respectively. Mixed infection was observed in 0.6 %. The chief helminths identified were: Toxocara vitulorum (3.6 %), Fasciola gigantica (3.2 %) Oesophagostomum radiatum (3.0 %) Strongyloides papillosus (2.4 %), Fasciola hepatica (2.2 %), ...

It is well known that the efficacy of a single oral dose of benzimidazoles against Trichuris spp. infections in humans and animals is poor, but is currently still used in control programmes against human trichuriasis. However, the route of the benzimidazoles from the treated host to Trichuris remains unknown. As parts of adult Trichuris are situated intracellularly in the caecum, they might be ...

Worm egg counts have been used for the assessment of nematode infections of sheep for many years. Different methods have been used, but recently the Stoll method (Stoll, 1930) and the McMaster Slide (Gordon & Whitlock, 1939) technique have almost entirely superseded the others. The McMaster technique is the best method, although it suffers from the slight disadvantage that eggs of Trichuris ovi...

The cyclooctadepsipeptide emodepside and its parent compound PF1022A are broad-spectrum nematicidal drugs which are able to eliminate nematodes resistant to other anthelmintics. The mode of action of cyclooctadepsipeptides is only partially understood, but involves the latrophilin Lat-1 receptor and the voltage- and calcium-activated potassium channel Slo-1. Genetic evidence suggests that emode...

BACKGROUND The intensity categories, or thresholds, currently used for Trichuris trichiura (ie. epg intensities of 1-999 (light); 1,000-9,999 epg (moderate), and ≥ 10,000 epg (heavy)) were developed in the 1980s, when there were little epidemiological data available on dose-response relationships. This study was undertaken to determine a threshold for T. trichiura-associated anemia in pregnant ...

There is a need to expand safe and effective treatment options for patients with moderate to severe psoriasis. This article hypothesizes one promising novel treatment option: Trichuris Suis. Epidemiological, experimental, and clinical evidence suggest that Trichuris Suis therapy may be both applicable and advantageous in the treatment of psoriasis. Epidemiologically, the de-worming of developed...
