... Abstract Gene expression was compared between resistant and susceptible Perendale lambs that had either never been exposed to gastrointestinal nematode challenge (had a naive immune system with respect to parasites) or had been naturally challenged on pasture with nematodes. Only a small number...

... on a single drug therapy for onchocerciasis for which there is evidence ofresistance. Wolbachia are attractive targets for control of filariasis as the endosymbiontsappear to be obligate for human filarial nematode vitality. Antibiotic studies in both animalmodels and in human trials indicate that disruption...

... Abstract The nematode Caenorhabditis elegans has proved to be an excellent model organismfor the study of development and aging. Many aging mutants have been discovered in thepast two decades, and much has been discovered about the physiology of long-lived mutants.It therefore seems surprising...

... the structure of nematodes revealed thatmany filariae (17 species reported to date, including most of the species pathogenic tohumans) harbored transovarially transmitted bacterial endosymbionts, subsequently determinedas belonging to the Wolbachia, clades C, D, and F. The Wolbachia are apparentlymutualistic...

... Abstract Wolbachia of arthropods and nematodes have contrasting patterns of association withtheir hosts. These patterns reflect the biological nature of the associations: parasitic in arthropodsand possibly mutualistic in filarial nematodes. Genome sequence data are aiding in boththe resolution...
