Human gastrointestinal nematode infections: are new control methods required?

B cells and antibodies are required for resistance to the parasitic gastrointestinal nematode Trichuris muris.

Previous studies using cell transfers and antibody receptor knockout mice have shown that B cells and antibodies are not essential components of the expulsion mechanism in Trichuris muris infections. Serum transfer experiments have given mixed results regarding the importance of antibodies in this infection model, and the role of B cells in initiating or maintaining T-cell responses has not bee...

Pathophysiology of Gastrointestinal Nematode Infections in the Ruminant

Recent advances in the understanding of the physiological and biochemical . consequences-of gastrointestinal nematode infections in ruminants are examined, particularly in relation to the nitrogen economy of the host and effects on animal productivity. Evidence is presented which suggests that, although there may be an apparent reduction in the net availability of nitrogen from the gut of infec...

A review of the epidemiology and control of gastrointestinal nematode infections in cattle in Zimbabwe.

In this review, the main gastrointestinal nematodes infecting cattle in Zimbabwe and the epidemiological factors influencing their occurrence are reviewed and discussed. Nineteen gastrointestinal nematode species that belong to seven families have been found to occur in cattle in Zimbabwe. The main genera reported to date are Cooperia, Haemonchus, Trichostrongylus and Oesophagostomum and the do...

Gastrointestinal Nematode Infection

Nematode infections are risk factors for staphylococcal infection in children.

Nematode infection may be a risk factor for pyogenic liver abscess in children and we hypothesized that the immunomodulation induced by those parasites would be a risk factor for any staphylococcal infection in children. The present study was designed to compare, within the same hospital, the frequency of intestinal nematodes and Toxocara infection in children with and without staphylococcal in...
