Nan Province, located in northern Thailand, is hyperendemic for parasite infections; the helminthic infection rate in 1,010 schoolchildren was 60.0% in 2001. Mass anthelmintic chemotherapy has been conducted with schoolchildren, and selective treatment has been given to people in the community, from 2002. The modified cellophane thick smear method was used to examine the prevalence and intensit...

The helminth parasites of the greater kudu from the Kruger National Park (KNP), South Africa, and the Etosha National Park (ENP), Namibia, were examined to determine the major patterns of spatial and demographic variation in community structure and to evaluate nonrandomness in parasite community assembly. Nonmetric multidimensional scaling ordination procedures were used to test for differences...

Most metazoan parasites that invade vertebrate hosts belong to three phyla: Platyhelminthes, Nematoda and Acanthocephala. Many of the parasitic members of these phyla are collectively known as helminths and are causative agents of many debilitating, deforming and lethal diseases of humans and animals. The North-East India Helminth Parasite Information Database (NEIHPID) project aimed to documen...

Helminth parasites were collected from 2 bushbuck, Tragelaphus scriptus, 2 red duiker, Cephalophus natalensis, 1 oribi, Ourebia ourebi, and 4 reedbuck, Redunca arundinum, that died or were culled in various parts of Natal. One trematode genus, 1 cestode genus and 12 nematode species were recovered. Haemonchus contortus. Ostertagia harrisi, Trichostrongylus capricola, Trichostrongylus vitrinus, ...

A literature survey revealed that 72 helminth species, including 14 known only to the generic level, had been reported from the digestive or respiratory tracts of 28 species of Anatidae in Africa. Most of the digeneans and nematodes reported, were cosmopolitan species that occur in a range of hosts. However, two groups of cestodes, one consisting of cosmopolitan or Eurasian species and the othe...

Biological control of parasitic nematodes of livestock is currently under development and represents another tool that may be integrated into helminth parasite control strategies. This paper presents a brief introduction to commercial sheep farming in South Africa and currently available nematode parasite control methods. These include the FAMACHA clinical assay, strategies of pasture managemen...

In this paper, we analyse the distributional patterns of adult helminth parasites of freshwater fishes with respect to the main hydrological basins of Mexico. We use the taxonomic distinctness and the variation in taxonomic distinctness to explore patterns of parasite diversity and how these patterns change between zoogeographical regions. We address questions about the factors that determine t...

Schistosoma parasites are blood flukes that infect an estimated 200 million people worldwide. In chronic infection with Schistosoma, the severe pathology, including liver fibrosis and splenomegaly, is caused by the immune response to the parasite eggs rather than the parasite itself. Parasite eggs induce a Th2 response characterized by the production of IL-4, IL-5 and IL-13, the alternative act...
